PIOGLITAZONE Tablet [Cadila Healthcare Limited]

The following serious adverse reactions are discussed elsewhere in the labeling:

• Congestive heart failure [see Boxed Warning and Warnings and Precautions (5.1)]
• Edema [see Warnings and Precautions (5.5)]
• Fractures [see Warnings and Precautions (5.6)]

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Over 8500 patients with type 2 diabetes have been treated with pioglitazone hydrochloride in randomized, doubleblind, controlled clinical trials, including 2605 patients with type 2 diabetes and macrovascular disease treated with pioglitazone hydrochloride in the PROactive clinical trial. In these trials, over 6000 patients have been treated with pioglitazone hydrochloride for six months or longer, over 4500 patients have been treated with pioglitazone hydrochloride for one year or longer, and over 3000 patients have been treated with pioglitazone hydrochloride for at least two years.

In six pooled 16- to 26- week placebo-controlled monotherapy and 16- to 24- week add-on combination therapy trials, the incidence of withdrawals due to adverse events was 4.5% for patients treated with pioglitazone hydrochloride and 5.8% for comparator-treated patients. The most common adverse events leading to withdrawal were related to inadequate glycemic control, although the incidence of these events was lower (1.5%) with pioglitazone hydrochloride than with placebo (3.0%).

In the PROactive trial, the incidence of withdrawals due to adverse events was 9.0% for patients treated with pioglitazone hydrochloride and 7.7% for placebo-treated patients. Congestive heart failure was the most common serious adverse event leading to withdrawal occurring in 1.3% of patients treated with pioglitazone hydrochloride and 0.6% of patients treated with placebo.

Common Adverse Events: 16- to 26- Week Monotherapy Trials

A summary of the incidence and type of common adverse events reported in three pooled 16- to 26- week placebo-controlled monotherapy trials of pioglitazone hydrochloride is provided in Table 1. Terms that are reported represent those that occurred at an incidence of > 5% and more commonly in patients treated with pioglitazone hydrochloride than in patients who received placebo. None of these adverse events were related to pioglitazone hydrochloride dose.

Common Adverse Events: 16- to 24- Week Add-on Combination Therapy Trials

A summary of the overall incidence and types of common adverse events reported in trials of pioglitazone hydrochloride add-on to sulfonylurea is provided in Table 2. Terms that are reported represent those that occurred at an incidence of > 5% and more commonly with the highest tested dose of pioglitazone hydrochloride.

A summary of the overall incidence and types of common adverse events reported in trials of pioglitazone hydrochloride add-on to metformin is provided in Table 3. Terms that are reported represent those that occurred at an incidence of > 5% and more commonly with the highest tested dose of pioglitazone hydrochloride.

Table 4 summarizes the incidence and types of common adverse events reported in trials of pioglitazone hydrochloride add-on to insulin. Terms that are reported represent those that occurred at an incidence of > 5% and more commonly with the highest tested dose of pioglitazone hydrochloride.

A summary of the overall incidence and types of common adverse events reported in the PROactive trial is provided in Table 5. Terms that are reported represent those that occurred at an incidence of > 5% and more commonly in patients treated with pioglitazone hydrochloride than in patients who received placebo.

Congestive Heart Failure

A summary of the incidence of adverse events related to congestive heart failure is provided in Table 6 for the 16- to 24- week add-on to sulfonylurea trials, for the 16- to 24- week add-on to insulin trials, and for the 16- to 24- week add-on to metformin trials. None of the events were fatal.

Patients with type 2 diabetes and NYHA class II or early class III congestive heart failure were randomized to receive 24 weeks of double-blind treatment with either pioglitazone at daily doses of 30 mg to 45 mg (n=262) or glyburide at daily doses of 10 mg to 15 mg (n=256). A summary of the incidence of adverse events related to congestive heart failure reported in this study is provided in Table 7.

Congestive heart failure events leading to hospitalization that occurred during the PROactive trial are summarized in Table 8.

Cardiovascular Safety

In the PROactive trial, 5238 patients with type 2 diabetes and a history of macrovascular disease were randomized to pioglitazone (N=2605), force-titrated up to 45 mg daily or placebo (N=2633) in addition to standard of care. Almost all patients (95%) were receiving cardiovascular medications (beta blockers, ACE inhibitors, angiotensin II receptor blockers, calcium channel blockers, nitrates, diuretics, aspirin, statins and fibrates). At baseline, patients had a mean age of 62 years, mean duration of diabetes of 9.5 years, and mean HbA1c of 8.1%. Mean duration of follow-up was 34.5 months.

The primary objective of this trial was to examine the effect of pioglitazone hydrochloride on mortality and macrovascular morbidity in patients with type 2 diabetes mellitus who were at high risk for macrovascular events. The primary efficacy variable was the time to the first occurrence of any event in a cardiovascular composite endpoint that included all-cause mortality, nonfatal myocardial infarction (MI) including silent MI, stroke, acute coronary syndrome, cardiac intervention including coronary artery bypass grafting or percutaneous intervention, major leg amputation above the ankle, and bypass surgery or revascularization in the leg. A total of 514 (19.7%) patients treated with pioglitazone hydrochloride and 572 (21.7%) placebo-treated patients experienced at least one event from the primary composite endpoint (hazard ratio 0.90; 95% Confidence Interval: 0.80, 1.02; p=0.10).

Although there was no statistically significant difference between pioglitazone hydrochloride and placebo for the three-year incidence of a first event within this composite, there was no increase in mortality or in total macrovascular events with pioglitazone hydrochloride. The number of first occurrences and total individual events contributing to the primary composite endpoint is shown in Table 9.

Weight Gain

Dose-related weight gain occurs when pioglitazone hydrochloride is used alone or in combination with other antidiabetic medications. The mechanism of weight gain is unclear but probably involves a combination of fluid retention and fat accumulation.

Tables 10 and 11 summarize the changes in body weight with pioglitazone hydrochloride and placebo in the 16- to 26- week randomized, double-blind monotherapy and 16- to 24- week combination add-on therapy trials and in the PROactive trial.

Edema

Edema induced from taking pioglitazone hydrochloride is reversible when pioglitazone hydrochloride is discontinued. The edema usually does not require hospitalization unless there is coexisting congestive heart failure. A summary of the frequency and types of edema adverse events occurring in clinical investigations of pioglitazone hydrochloride is provided in Table 12.

Hepatic Effects

There has been no evidence of induced hepatotoxicity with pioglitazone hydrochloride controlled clinical trial database to date. One randomized, double-blind 3-year trial comparing pioglitazone hydrochloride to glyburide as add-on to metformin and insulin therapy was specifically designed to evaluate the incidence of serum ALT elevation to greater than three times the upper limit of the reference range, measured every eight weeks for the first 48 weeks of the trial then every 12 weeks thereafter. A total of 3/1051 (0.3%) patients treated with pioglitazone hydrochloride and 9/1046 (0.9%) patients treated with glyburide developed ALT values greater than three 3 times the upper limit of the reference range. None of the patients treated with pioglitazone hydrochloride in the pioglitazone hydrochloride controlled clinical trial database to date have had a serum ALT greater than three times the upper limit of the reference range and a corresponding total bilirubin greater than two times the upper limit of the reference range, a combination predictive of the potential for severe drug-induced liver injury.

Hypoglycemia

In the pioglitazone hydrochloride clinical trials, adverse events of hypoglycemia were reported based on clinical judgment of the investigators and did not require confirmation with fingerstick glucose testing.

In the 16-week add-on to sulfonylurea trial, the incidence of reported hypoglycemia was 3.7% with pioglitazone 30 mg and 0.5% with placebo. In the 16-week add-on to insulin trial, the incidence of reported hypoglycemia was 7.9% with pioglitazone 15 mg, 15.4% with pioglitazone 30 mg, and 4.8% with placebo.

The incidence of reported hypoglycemia was higher with pioglitazone 45 mg compared to pioglitazone 30 mg in both the 24-week add-on to sulfonylurea trial (15.7% vs. 13.4%) and in the 24-week add-on to insulin trial (47.8% vs. 43.5%).

Three patients in these four trials were hospitalized due to hypoglycemia. All three patients were receiving pioglitazone 30 mg (0.9%) in the 24-week add-on to insulin trial. An additional 14 patients reported severe hypoglycemia (defined as causing considerable interference with patient's usual activities) that did not require hospitalization. These patients were receiving pioglitazone 45 mg in combination with sulfonylurea (n=2) or pioglitazone 30 mg or 45 mg in combination with insulin (n=12).

Urinary Bladder Tumors

Tumors were observed in the urinary bladder of male rats in the two-year carcinogenicity study [see Nonclinical Toxicology (13.1)]. During the three year PROactive clinical trial, 14 patients out of 2605 (0.54%) randomized to pioglitazone hydrochloride and 5 out of 2633 (0.19%) randomized to placebo were diagnosed with bladder cancer. After excluding patients in whom exposure to study drug was less than one year at the time of diagnosis of bladder cancer, there were 6 (0.23%) cases on pioglitazone hydrochloride and two (0.08%) cases on placebo. After completion of the trial, a large subset of patients was observed for up to 10 additional years, with little additional exposure to pioglitazone hydrochloride. During the 13 years of both PROactive and observational follow-up, the occurrence of bladder cancer did not differ between patients randomized to pioglitazone hydrochloride or placebo (HR =1.00; 95% CI: 0.59 to 1.72) [see Warnings and Precautions (5.4)].

Laboratory Abnormalities

Hematologic Effects

Pioglitazone hydrochloride may cause decreases in hemoglobin and hematocrit. In placebo-controlled monotherapy trials, mean hemoglobin values declined by 2% to 4% in patients treated with pioglitazone hydrochloride compared with a mean change in hemoglobin of -1% to +1% in placebo-treated patients. These changes primarily occurred within the first 4 to 12 weeks of therapy and remained relatively constant thereafter. These changes may be related to increased plasma volume associated with pioglitazone hydrochloride therapy and are not likely to be associated with any clinically significant hematologic effects.

Creatine Phosphokinase

During protocol-specified measurement of serum creatine phosphokinase (CPK) in pioglitazone hydrochloride clinical trials, an isolated elevation in CPK to greater than 10 times the upper limit of the reference range was noted in nine (0.2%) patients treated with pioglitazone hydrochloride (values of 2150 to 11400 IU/L) and in no comparator-treated patients. Six of these nine patients continued to receive pioglitazone hydrochloride, two patients were noted to have the CPK elevation on the last day of dosing and one patient discontinued pioglitazone hydrochloride due to the elevation. These elevations resolved without any apparent clinical sequelae. The relationship of these events to pioglitazone hydrochloride therapy is unknown.

IMATINIB MESYLATE Tablet, Film Coated [Apotex Corp]

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Chronic Myeloid Leukemia

The majority of imatinib-treated patients experienced adverse reactions at some time. Imatinib was discontinued due to drug-related adverse reactions in 2.4% of patients receiving imatinib mesylate in the randomized trial of newly diagnosed patients with Ph+ CML in chronic phase comparing imatinib mesylate versus IFN+Ara-C, and in 12.5% of patients receiving imatinib mesylate in the randomized trial of newly diagnosed patients with Ph+ CML in chronic phase comparing imatinib mesylate and nilotinib. Imatinib mesylate was discontinued due to drug-related adverse reactions in 4% of patients in chronic phase after failure of interferon-alpha therapy, in 4% of patients in accelerated phase and in 5% of patients in blast crisis.

The most frequently reported drug-related adverse reactions were edema, nausea and vomiting, muscle cramps, musculoskeletal pain, diarrhea and rash (Table 2 and Table 3 for newly diagnosed CML, Table 4 for other CML patients). Edema was most frequently periorbital or in lower limbs and was managed with diuretics, other supportive measures, or by reducing the dose of Imatinib [see Dosage and Administration (2.13)]. The frequency of severe superficial edema was 1.5% to 6%.

A variety of adverse reactions represent local or general fluid retention including pleural effusion, ascites, pulmonary edema and rapid weight gain with or without superficial edema. These reactions appear to be dose related, were more common in the blast crisis and accelerated phase studies (where the dose was 600 mg/day), and are more common in the elderly. These reactions were usually managed by interrupting imatinib mesylate treatment and using diuretics or other appropriate supportive care measures. These reactions may be serious or life threatening.

Adverse reactions, regardless of relationship to study drug, that were reported in at least 10% of the imatinib mesylate treated patients are shown in Tables 2, 3, and 4.

Hematologic and Biochemistry Laboratory Abnormalities

Cytopenias, and particularly neutropenia and thrombocytopenia, were a consistent finding in all studies, with a higher frequency at doses greater than or equal to 750 mg (Phase 1 study). The occurrence of cytopenias in CML patients was also dependent on the stage of the disease.

In patients with newly diagnosed CML, cytopenias were less frequent than in the other CML patients (see Tables 5, 6, and 7). The frequency of Grade 3 or 4 neutropenia and thrombocytopenia was between 2- and 3-fold higher in blast crisis and accelerated phase compared to chronic phase (see Tables 4 and 5). The median duration of the neutropenic and thrombocytopenic episodes varied from 2 to 3 weeks, and from 2 to 4 weeks, respectively.

These reactions can usually be managed with either a reduction of the dose or an interruption of treatment with imatinib mesylate, but may require permanent discontinuation of treatment.

1CTC Grades: neutropenia (Grade 3 greater than or equal to 0.5 to 1.0 x 109/L, Grade 4 less than 0.5 x 109/L), thrombocytopenia (Grade 3 greater than or equal to 10 to 50 x 109/L, Grade 4 less than 10 x 109/L), anemia (hemoglobin greater than or equal to 65 to 80 g/L, Grade 4 less than 65 g/L), elevated creatinine (Grade 3 greater than 3 to 6 x upper limit normal range [ULN], Grade 4 greater than 6 x ULN), elevated bilirubin (Grade 3 greater than 3 to 10 x ULN, Grade 4 greater than 10 x ULN), elevated alkaline phosphatase (Grade 3 greater than 5 to 20 x ULN, Grade 4 greater than 20 x ULN), elevated SGOT or SGPT (Grade 3 greater than 5 to 20 x ULN, Grade 4 greater than 20 x ULN)

Hepatotoxicity
Severe elevation of transaminases or bilirubin occurred in approximately 5% of CML patients (see Tables 6 and 7) and were usually managed with dose reduction or interruption (the median duration of these episodes was approximately 1 week). Treatment was discontinued permanently because of liver laboratory abnormalities in less than 1.0% of CML patients. One patient, who was taking acetaminophen regularly for fever, died of acute liver failure.

Adverse Reactions in Pediatric Population

Single agent therapy

The overall safety profile of pediatric patients treated with imatinib mesylate in 93 children studied was similar to that found in studies with adult patients, except that musculoskeletal pain was less frequent (20.5%) and peripheral edema was not reported. Nausea and vomiting were the most commonly reported individual adverse reactions with an incidence similar to that seen in adult patients. Most patients experienced adverse reactions at some time during the study. The incidence of Grade 3/4 events across all types of adverse reactions was 75%; the events with the highest Grade 3/4 incidence in CML pediatric patients were mainly related to myelosuppression.

Adverse Reactions in Other Subpopulations

In older patients (greater than or equal to  65 years old), with the exception of edema, where it was more frequent, there was no evidence of an increase in the incidence or severity of adverse reactions. In women there was an increase in the frequency of neutropenia, as well as Grade 1/2 superficial edema, headache, nausea, rigors, vomiting, rash, and fatigue. No differences were seen that were related to race but the subsets were too small for proper evaluation.

Acute Lymphoblastic Leukemia

The adverse reactions were similar for Ph+ ALL as for Ph+ CML. The most frequently reported drug-related adverse reactions reported in the Ph+ ALL studies were mild nausea and vomiting, diarrhea, myalgia, muscle cramps and rash. Superficial edema was a common finding in all studies and were described primarily as periorbital or lower limb edemas. These edemas were reported as Grade 3/4 events in 6.3% of the patients and may be managed with diuretics, other supportive measures, or in some patients by reducing the dose of imatinib mesylate.

Myelodysplastic/Myeloproliferative Diseases

Adverse reactions, regardless of relationship to study drug, that were reported in at least 10% of the patients treated with imatinib mesylate for MDS/MPD in the Phase 2 study, are shown in Table 9.  

Table 9: Adverse Reactions Regardless of Relationship to Study Drug Reported (More than One Patient) in MPD Patients in the Phase 2 Study (greater than or equal to 10% All Patients) All Grades

Aggressive Systemic Mastocytosis

All ASM patients experienced at least one adverse reaction at some time. The most frequently reported adverse reactions were diarrhea, nausea, ascites, muscle cramps, dyspnea, fatigue, peripheral edema, anemia, pruritus, rash and lower respiratory tract infection. None of the 5 patients in the Phase 2 study with ASM discontinued imatinib mesylate due to drug-related adverse reactions or abnormal laboratory values.

Hypereosinophilic Syndrome and Chronic Eosinophilic Leukemia

The safety profile in the HES/CEL patient population does not appear to be different from the safety profile of imatinib mesylate observed in other hematologic malignancy populations, such as Ph+ CML. All patients experienced at least one adverse reaction, the most common being gastrointestinal, cutaneous and musculoskeletal disorders. Hematological abnormalities were also frequent, with instances of CTC Grade 3 leukopenia, neutropenia, lymphopenia, and anemia.

Dermatofibrosarcoma Protuberans

Adverse reactions, regardless of relationship to study drug, that were reported in at least 10% of the 12 patients treated with imatinib mesylate for DFSP in the Phase 2 study are shown in Table 10.

DOXORUBICIN HYDROCHLORIDE Injection, Solution [Pfizer Laboratories Div Pfizer Inc]

DOXORUBICIN (dok-suh-roo-buh-sin) HYDROCHLORIDE
Injection, for intravenous use

What is the most important information I should know about Doxorubicin?

Doxorubicin may cause serious side effects including:

• Heart failure. Doxorubicin may cause heart muscle damage that may lead to heart failure, which is a condition in which the heart does not pump well. Heart failure is irreversible in some cases and can lead to death. Heart failure can happen during your treatment with Doxorubicin or months to years after stopping treatment. Your risk of heart muscle damage increases with higher total amounts of doxorubicin hydrochloride that you receive in your lifetime. Your risk of heart failure is higher if you:
  • already have other heart problems
  • have had or are currently receiving radiation therapy to your chest
  • have had treatment with certain other anti-cancer medicines
  • take other medicines that can have severe side effects on your heart

  Tell your doctor if you get any of these symptoms of heart failure during or after treatment with Doxorubicin:

  extreme tiredness or weakness shortness of breath

  fast heartbeat swelling of your feet and ankles

  Your doctor will do tests to check the strength of your heart muscle before, during, and after your treatment with Doxorubicin.

• Risk of new cancers. You may have an increased risk of developing certain blood cancers called acute myelogenous leukemia (AML) or myelodysplastic syndrome (MDS) after treatment with doxorubicin. Talk with your doctor about your risk of developing new cancers if you take Doxorubicin.
• Skin damage near the vein where Doxorubicin is given (Injection site reaction). Doxorubicin can damage the skin if it leaks out of the vein. Symptoms of infusion reaction include blisters and skin sores at injection site which may require skin grafts.
• Decreased blood cell counts. Doxorubicin can cause a decrease in neutrophils (a type of white blood cells important in fighting bacterial infections) and platelets (important for clotting and to control bleeding). This may lead to a serious infection, the need for blood transfusions, treatment in a hospital and death. Your doctor will check your blood cell count during your treatment with Doxorubicin and after you have stopped your treatment. Call your doctor right away if you get a fever (temperature of 100.4 F or greater) or chills with shivering.

What is Doxorubicin?

Doxorubicin is a prescription medicine used to treat certain types of cancers. Doxorubicin may be used alone or along with other anti-cancer medicines.

Who should not receive Doxorubicin?

Do not receive Doxorubicin if:

• you have had a recent heart attack or have severe heart problems
• your blood cell counts (platelets, red blood cells, and white blood cells) are very low because of prior chemotherapy
• you have a severe liver problem
• you have had a serious allergic reaction to doxorubicin hydrochloride

What should I tell my doctor before receiving Doxorubicin?

Before you receive Doxorubicin, tell your doctor if you:

• have heart problems including heart failure
• are currently receiving radiation therapy or plan to receive radiation to the chest
• have severe liver problems
• have had an allergic reaction to doxorubicin
• have any other medical conditions
• are pregnant or plan to become pregnant. Doxorubicin can harm your unborn baby. Women who are able to become pregnant and men who take Doxorubicin should use effective birth control (contraception) during treatment and for 6 months after treatment. Talk to your doctor about birth control methods. If you or your partner becomes pregnant, tell your doctor right away.
• are breastfeeding or plan to breast feed. Doxorubicin can pass into your breast milk and harm your baby. You and your doctor should decide if you will receive Doxorubicin or breastfeed. You should not do both.

Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Doxorubicin can interact with other medicines. Do not start any new medicine before you talk with the doctor that prescribed Doxorubicin.

Know the medicines you take. Keep a list to show your doctor and pharmacist each time you get a new medicine.

How will I receive Doxorubicin?

• Doxorubicin will be given to you into your vein.

What are the possible side effects of Doxorubicin?

Doxorubicin may cause serious side effects, including:

Doxorubicin may cause lower sperm counts and sperm problems in men.

This could affect your ability to father a child and cause birth defects. Talk to your healthcare provider if this is a concern for you. Talk to your healthcare provider about family planning options that might be right for you.

Irreversible amenorrhea or early menopause. Your periods (menstrual cycle) may completely stop when you receive Doxorubicin. Your periods may or may not return following treatment. Talk to your healthcare provider about family planning options that might be right for you.

The most common side effects of Doxorubicin include:

• Total hair loss (alopecia). Your hair may re-grow after your treatment.
• nausea

DOXORUBICIN HYDROCHLORIDE Injection, Solution [Pfizer Laboratories Div Pfizer Inc]

PROPAFENONE HYDROCHLORIDE Capsule, Extended Release [American Health Packaging]

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The data described below reflect exposure to propafenone ER capsules 225 mg BID in 126 patients, to propafenone ER capsules 325 mg BID in 135 patients, to propafenone ER capsules 425 mg BID in 136 patients, and to placebo in 126 patients for up to 39 weeks (mean 20 weeks) in a placebo controlled trial (RAFT) conducted in the U.S. The most commonly reported adverse events with propafenone (>5% and greater than placebo), excluding those not reasonably associated with the use of the drug or because they were associated with the condition being treated, were dizziness, palpitations, chest pain, dyspnea, taste disturbance, nausea, fatigue, anxiety, constipation, upper respiratory tract infection, edema, and influenza. The frequency of discontinuation due to adverse events was 17%, and the rate was highest during the first 14 days of treatment.

Cardiac-related adverse events occurring in ≥ 2% of the patients in any of the RAFT propafenone ER capsules treatment groups and more common with propafenone than with placebo, excluding those that are common in the population and those not plausibly related to drug therapy, included the following: angina pectoris, atrial flutter, AV block first degree, bradycardia, congestive cardiac failure, cardiac murmur, edema, dyspnea, rales, wheezing, and cardioactive drug level above therapeutic.

Propafenone prolongs the PR and QRS intervals in patients with atrial and ventricular arrhythmias. Prolongation of the QRS interval makes it difficult to interpret the effect of propafenone on the QT interval [ see CLINICAL PHARMACOLOGY ( 12.2)] .

Non-cardiac related adverse events occurring in ≥ 2% of the patients in any of the RAFT propafenone ER capsules treatment groups and more common with propafenone than with placebo, excluding those that are common in the population and those not plausibly related to drug therapy, included the following: blurred vision, constipation, diarrhea, dry mouth, flatulence, nausea, vomiting, fatigue, weakness, upper respiratory tract infection, blood alkaline phosphatase increased, hematuria, muscle weakness, dizziness (excluding vertigo), headache, taste disturbance, tremor, somnolence, anxiety, depression, ecchymosis.

No clinically important differences in incidence of adverse reactions were noted by age or gender. Too few non-Caucasian patients were enrolled to assess adverse events according to race.

The data described in this section are derived from a clinical trial database consisting of 9803 adult and pediatric patients exposed to one or more doses of risperidone tablets for the treatment of schizophrenia, bipolar mania, autistic disorder, and other psychiatric disorders in pediatrics and elderly patients with dementia. Of these 9803 patients, 2687 were patients who received risperidone tablets while participating in double-blind, placebo-controlled trials. The conditions and duration of treatment with risperidone tablets varied greatly and included (in overlapping categories) double-blind, fixed- and flexible-dose, placebo- or active-controlled studies and open-label phases of studies, inpatients and outpatients, and short-term (up to 12 weeks) and longer-term (up to 3 years) exposures. Safety was assessed by collecting adverse events and performing physical examinations, vital signs, body weights, laboratory analyses, and ECGs.

Discontinuations Due to Adverse Reactions
Schizophrenia - Adults  

Approximately 7% (39/564) of risperidone tablets-treated patients in double-blind, placebo-controlled trials discontinued treatment due to an adverse reaction, compared with 4% (10/225) who were receiving placebo. The adverse reactions associated with discontinuation in 2 or more risperidone tablets-treated patients were:

Discontinuation for extrapyramidal symptoms (including Parkinsonism, akathisia, dystonia, and tardive dyskinesia) was 1% in placebo-treated patients, and 3.4% in active control-treated patients in a double-blind, placebo- and active-controlled trial.

Schizophrenia – Pediatrics
Approximately 7% (7/106), of risperidone tablets-treated patients discontinued treatment due to an adverse reaction in a double-blind, placebo-controlled trial, compared with 4% (2/54) placebo-treated patients. The adverse reactions associated with discontinuation for at least one risperidone tablets-treated patient were dizziness (2%), somnolence (1%), sedation (1%), lethargy (1%), anxiety (1%), balance disorder (1%), hypotension (1%), and palpitation (1%).

Bipolar Mania – Adults
In double-blind, placebo-controlled trials with risperidone tablets as monotherapy, approximately 6% (25/448) of risperidone tablets-treated patients discontinued treatment due to an adverse event, compared with approximately 5% (19/424) of placebo-treated patients. The adverse reactions associated with discontinuation in risperidone tablets-treated patients were:

Bipolar Mania – Pediatrics
In a double-blind, placebo-controlled trial 12% (13/111) of risperidone tablets-treated patients discontinued due to an adverse reaction, compared with 7% (4/58) of placebo-treated patients. The adverse reactions associated with discontinuation in more than one risperidone tablets-treated pediatric patient were nausea (3%), somnolence (2%), sedation (2%), and vomiting (2%).

Autistic Disorder – Pediatrics

In the two 8-week, placebo-controlled trials in pediatric patients treated for irritability associated with autistic disorder (n = 156), one risperidone tablets-treated patient discontinued due to an adverse reaction (Parkinsonism), and one placebo-treated patient discontinued due to an adverse event.

Dose Dependency of Adverse Reactions in Clinical Trials
Extrapyramidal Symptoms
Data from two fixed-dose trials in adults with schizophrenia provided evidence of dose-relatedness for extrapyramidal symptoms associated with risperidone tablets treatment.

Two methods were used to measure extrapyramidal symptoms (EPS) in an 8-week trial comparing 4 fixed doses of risperidone tablets (2, 6, 10, and 16 mg/day), including (1) a Parkinsonism score (mean change from baseline) from the Extrapyramidal Symptom Rating Scale, and (2) incidence of spontaneous complaints of EPS: 

Similar methods were used to measure extrapyramidal symptoms (EPS) in an 8-week trial comparing 5 fixed doses of risperidone tablets (1, 4, 8, 12, and 16 mg/day):         

Dystonia
Class Effect: Symptoms of dystonia, prolonged abnormal contractions of muscle groups, may occur in susceptible individuals during the first few days of treatment. Dystonic symptoms include: spasm of the neck muscles, sometimes progressing to tightness of the throat, swallowing difficulty, difficulty breathing, and/or protrusion of the tongue. While these symptoms can occur at low doses, they occur more frequently and with greater severity with high potency and at higher doses of first generation antipsychotic drugs. An elevated risk of acute dystonia is observed in males and younger age groups.

Other Adverse Reactions
Adverse event data elicited by a checklist for side effects from a large study comparing 5 fixed doses of risperidone tablets (1, 4, 8, 12, and 16 mg/day) were explored for dose-relatedness of adverse events. A Cochran-Armitage Test for trend in these data revealed a positive trend (p<0.05) for the following adverse reactions: somnolence, vision abnormal, dizziness, palpitations, weight increase, erectile dysfunction, ejaculation disorder, sexual function abnormal, fatigue, and skin discoloration.

Changes in Body Weight

Weight gain was observed in short-term, controlled trials and longer-term uncontrolled studies in adult and pediatric patients [see Warnings and Precautions (5.5), Adverse Reactions (6), and Use in Specific Populations (8.4)].

Changes in ECG Parameters
Between-group comparisons for pooled placebo-controlled trials in adults revealed no statistically significant differences between risperidone and placebo in mean changes from baseline in ECG parameters, including QT, QTc, and PR intervals, and heart rate. When all risperidone tablets doses were pooled from randomized controlled trials in several indications, there was a mean increase in heart rate of 1 beat per minute compared to no change for placebo patients. In short-term schizophrenia trials, higher doses of risperidone (8-16 mg/day) were associated with a higher mean increase in heart rate compared to placebo (4-6 beats per minute). In pooled placebo-controlled acute mania trials in adults, there were small decreases in mean heart rate, similar among all treatment groups.

In the two placebo-controlled trials in children and adolescents with autistic disorder (aged 5 – 16 years) mean changes in heart rate were an increase of 8.4 beats per minute in the risperidone tablets groups and 6.5 beats per minute in the placebo group. There were no other notable ECG changes.

In a placebo-controlled acute mania trial in children and adolescents (aged 10 – 17 years), there were no significant changes in ECG parameters, other than the effect of risperidone tablets to transiently increase pulse rate (< 6 beats per minute). In two controlled schizophrenia trials in adolescents (aged 13 – 17 years), there were no clinically meaningful changes in ECG parameters including corrected QT intervals between treatment groups or within treatment groups over time.

LISINOPRIL Tablet [Preferred Pharmaceuticals Inc.]

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice.

Hypertension

In clinical trials in patients with hypertension treated with Lisinopril, 5.7% of patients on Lisinopril discontinued with adverse reactions.

The following adverse reactions (events 2% greater on Lisinopril than on placebo) were observed with Lisinopril alone: headache (by 3.8%), dizziness (by 3.5%), cough (by 2.5%).

Heart Failure

In patients with systolic heart failure treated with Lisinopril for up to four years, 11% discontinued therapy with adverse reactions. In controlled studies in patients with heart failure, therapy was discontinued in 8.1% of patients treated with Lisinopril for 12 weeks, compared to 7.7% of patients treated with placebo for 12 weeks.

The following adverse reactions (events 2% greater on Lisinopril than on placebo) were observed with Lisinopril: hypotension (by 3.8%), chest pain (by 2.1%).

In the two-dose ATLAS trial [see Clinical Studies (14.2)] in heart failure patients, withdrawals due to adverse reactions were not different between the low and high groups, either in total number of discontinuation (17-18%) or in rare specific reactions (< 1%). The following adverse reactions, mostly related to ACE inhibition, were reported more commonly in the high dose group:

Acute Myocardial Infarction

Patients treated with Lisinopril had a higher incidence of hypotension (by 5.3%) and renal dysfunction (by 1.3%) compared with patients not taking Lisinopril.

Other clinical adverse reactions occurring in 1 % or higher of patients with hypertension or heart failure treated with Lisinopril in controlled clinical trials and do not appear in other sections of labeling are listed below:

Body as a whole: Fatigue, asthenia, orthostatic effects.

Digestive: Pancreatitis, constipation, flatulence, dry mouth, diarrhea.

Hematologic: Rare cases of bone marrow depression, hemolytic anemia, leukopenia/neutropenia and thrombocytopenia.

Endocrine: Diabetes mellitus, inappropriate antidiuretic hormone secretion.

Metabolic: Gout.

Skin: Urticaria, alopecia, photosensitivity, erythema, flushing, diaphoresis, cutaneous pseudolymphoma, toxic epidermal necrolysis, Stevens-Johnson syndrome, and pruritus.

Special Senses: Visual loss, diplopia, blurred vision, tinnitus, photophobia, taste disturbances, olfactory disturbance.

Urogenital: Impotence.

Miscellaneous: A symptom complex has been reported which may include a positive ANA, an elevated erythrocyte sedimentation rate, arthralgia/arthritis, myalgia, fever, vasculitis, eosinophilia, leukocytosis, paresthesia and vertigo. Rash, photosensitivity or other dermatological manifestations may occur alone or in combination with these symptoms.

Clinical Laboratory Test Findings

Serum Potassium: In clinical trials hyperkalemia (serum potassium greater than 5.7 mEq/L) occurred in 2.2% and 4.8% of Lisinopril-treated patients with hypertension and heart failure, respectively [see Warnings and Precautions (5.5)].

Creatinine, Blood Urea Nitrogen: Minor increases in blood urea nitrogen and serum creatinine, reversible upon discontinuation of therapy, were observed in about 2% of patients with hypertension treated with Lisinopril alone. Increases were more common in patients receiving concomitant diuretics and in patients with renal artery stenosis [see Warnings and Precautions (5.4)]. Reversible minor increases in blood urea nitrogen and serum creatinine were observed in 11.6% of patients with heart failure on concomitant diuretic therapy. Frequently, these abnormalities resolved when the dosage of the diuretic was decreased.

Patients with acute myocardial infarction in the GISSI-3 trial treated with Lisinopril had a higher (2.4% versus 1.1% in placebo) incidence of renal dysfunction in-hospital and at six weeks (increasing creatinine concentration to over 3 mg/dL or a doubling or more of the baseline serum creatinine concentration).

Hemoglobin and Hematocrit: Small decreases in hemoglobin and hematocrit (mean decreases of approximately 0.4 g% and 1.3 vol%, respectively) occurred frequently in patients treated with Lisinopril but were rarely of clinical importance in patients without some other cause of anemia. In clinical trials, less than 0.1% of patients discontinued therapy due to anemia.

Drug Interactions

Inhibitors of CYP3A4 and CYP2D6

The concomitant use of Hydrocodone Bitartrate and Acetaminophen Tablets and CYP3A4 inhibitors, such as macrolide antibiotics (e.g., erythromycin), azole-antifungal agents (e.g. ketoconazole), and protease inhibitors (e.g., ritonavir), can increase the plasma concentration of the hydrocodone from Hydrocodone Bitartrate and Acetaminophen Tablets, resulting in increased or prolonged opioid effects. These effects could be more pronounced with concomitant use of Hydrocodone Bitartrate and Acetaminophen Tablets and both CYP3A4 and CYP2D6 inhibitors, particularly when an inhibitor is added after a stable dose of Hydrocodone Bitartrate and Acetaminophen Tablets is achieved [see  WARNINGS].

After stopping a CYP3A4 inhibitor, as the effects of the inhibitor decline, the hydrocodone plasma concentration will decrease [see CLINICAL PHARMACOLOGY], resulting in decreased opioid efficacy or a withdrawal syndrome in patients who had developed physical dependence to Hydrocodone Bitartrate and Acetaminophen Tablets.

If concomitant use is necessary, consider dosage reduction of Hydrocodone Bitartrate and Acetaminophen Tablets until stable drug effects are achieved. Follow patients for respiratory depression and sedation at frequent intervals. If a CYP3A4 inhibitor is discontinued, consider increasing the Hydrocodone Bitartrate and Acetaminophen Tablets dosage until stable drug effects are achieved. Follow for signs or symptoms of opioid withdrawal.

Inducer of CYP3A4
The concomitant use of Hydrocodone Bitartrate and Acetaminophen Tablets and CYP3A4 inducers, such as rifampin, carbamazepine, and phenytoin, can decrease the plasma concentration of hydrocodone [see  CLINICAL PHARMACOLOGY], resulting in decreased efficacy or onset of a withdrawal syndrome in patients who have developed physical dependence to hydrocodone [see WARNINGS].
After stopping a CYP3A4 inducer, as the effects of the inducer decline, the hydrocodone plasma concentration will increase [see CLINICAL PHARMACOLOGY], which could increase or prolong both the therapeutic effects and adverse reactions, and may cause serious respiratory depression.

If concomitant use is necessary, consider increasing the Hydrocodone Bitartrate and Acetaminophen Tablets dosage until stable drug effects are achieved. follow the patient for signs and symptoms of opioid withdrawal. If a CYP3A4 inducer is discontinued, consider Hydrocodone Bitartrate and Acetaminophen Tablets dosage reduction and follow for signs of respiratory depression.

Benzodiazepines and other CNS Depressants
Due to additive pharmacologic effect, the concomitant use of benzodiazepines and other CNS depressants, such as benzodiazepines and other sedative hypnotics, anxiolytics, and tranquilizers, muscle relaxants, general anesthetics, antipsychotics, and other opioids, including alcohol, can increase the risk of hypotension, respiratory depression, profound sedation, coma, and death.

Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients closely for signs of respiratory depression and sedation [see WARNINGS]. 

Serotonergic Drugs 

The concomitant use of opioids with other drugs that affect the serotonergic neurotransmitter system, such as selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), triptans, 5-HT3 receptor antagonists, drugs that affect the serotonin neurotransmitter system (e.g., mirtazapine, trazodone, tramadol), and monoamine oxidase (MAO) inhibitors (those intended to treat psychiatric disorders and also others, such as linezolid and intravenous methylene blue), has resulted in serotonin syndrome. [see PRECAUTIONS; Information for Patients].

If concomitant use is warranted, carefully follow the patient, particularly during treatment initiation and dose adjustment. Discontinue Hydrocodone Bitartrate and Acetaminophen Tablets if serotonin syndrome is suspected.

Monoamine Oxidase Inhibitors (MAOIs)
The concomitant use of opioids and MAOIs, such as phenelzine, tranylcypromine, or linezolid, may manifest as serotonin syndrome, or opioid toxicity (e.g., respiratory depression, coma) [see WARNINGS].
The use of Hydrocodone Bitartrate and Acetaminophen Tablets is not recommended for patients taking MAOIs or within 14 days of stopping such treatment.
If urgent use of an opioid is necessary, use test doses and frequent titration of small doses to treat pain while closely monitoring blood pressure and signs and symptoms of CNS and respiratory depression.

Mixed Agonist/Antagonist and Partial Agonist Opioid Analgesics
The concomitant use of opioids with other opioid analgesics, such as butorphanol, nalbuphine, pentazocine, may reduce the analgesic effect of Hydrocodone Bitartrate and Acetaminophen Tablets and/or precipitate withdrawal symptoms.
Advise patient to avoid concomitant use of these drugs.

Muscle Relaxants
Hydrocodone Bitartrate and Acetaminophen Tablets may enhance the neuromuscular blocking action of skeletal muscle relaxants and produce an increased degree of respiratory depression.
If concomitant use is warranted, monitor patients for signs of respiratory depression that may be greater than otherwise expected and decrease the dosage of Hydrocodone Bitartrate and Acetaminophen Tablets and/or the muscle relaxant as necessary.

Diuretics
Opioids can reduce the efficacy of diuretics by inducing the release of antidiuretic hormone. If concomitant use is warranted, follow patients for signs of diminished diuresis and/or effects on blood pressure and increase the dosage of the diuretic as needed.

Anticholinergic Drugs
The concomitant use of anticholinergic drugs may increase risk of urinary retention and/or severe constipation, which may lead to paralytic ileus.
If concomitant use is warranted, follow patients for signs and symptoms of urinary retention or reduced gastric motility when Hydrocodone Bitartrate and Acetaminophen Tablets are used concomitantly with anticholinergic drugs.

Drug/Laboratory Test Interactions:

Acetaminophen may produce false-positive test results for urinary 5-hydroxyindoleacetic acid.

Carcinogenesis, Mutagenesis, Impairment of Fertility:

Carcinogenesis
Long-term studies to evaluate the carcinogenic potential of the combination of Hydrocodone Bitartrate and Acetaminophen Tablets have not been conducted.
Long-term studies in mice and rats have been completed by the National Toxicology Program to evaluate the carcinogenic potential of acetaminophen. In 2-year feeding studies, F344/N rats and B6C3F1 mice were fed a diet containing acetaminophen up to 6000 ppm.
Female rats demonstrated equivocal evidence of carcinogenic activity based on increased incidences of mononuclear cell leukemia at 0.8 times the maximum human daily dose (MHDD) of 4 grams/day, based on a body surface area comparison. In contrast, there was no evidence of carcinogenic activity in male rats that received up to 0.7 times or mice at up to 1.2-1.4 times the MHDD, based on a body surface area comparison.

Mutagenesis
In the published literature, acetaminophen has been reported to be clastogenic when administered at 1500 mg/kg/day to the rat model (3.6-times the MHDD, based on a body surface area comparison). In contrast, no clastogenicity was noted at a dose of 750 mg/kg/day (1.8-times the MHDD, based on a body surface area comparison), suggesting a threshold effect.

Impairment of Fertility
In studies conducted by the National Toxicology Program, fertility assessments with acetaminophen have been completed in Swiss CD-1 mice via a continuous breeding study.
There were no effects on fertility parameters in mice consuming up to 1.7 times the MHDD of acetaminophen, based on a body surface area comparison. Although there was no effect on sperm motility or sperm density in the epididymis, there was a significant increase in the percentage of abnormal sperm in mice consuming 1.78 times the MHDD (based on a body surface comparison) and there was a reduction in the number of mating pairs producing a fifth litter at this dose, suggesting the potential for cumulative toxicity with chronic administration of acetaminophen near the upper limit of daily dosing.
Published studies in rodents report that oral acetaminophen treatment of male animals at doses that are 1.2 times the MHDD and greater (based on a body surface comparison) result in decreased testicular weights, reduced spermatogenesis, reduced fertility, and reduced implantation sites in females given the same doses. These effects appear to increase with the duration of treatment. The clinical significance of these findings is not
known.

Infertility
Chronic use of opioids may cause reduced fertility in females and males of reproductive potential. It is not known whether these effects on fertility are reversible [see ADVERSE REACTIONS].

Pregnancy:

Teratogenic Effects: 

Pregnancy Category C

There are no adequate and well-controlled studies in pregnant women. Hydrocodone Bitartrate and Acetaminophen Tablets should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Nonteratogenic Effects

Fetal/Neonatal Adverse Reactions

Prolonged use of opioid analgesics during pregnancy for medical or nonmedical purposes can result in physical dependence in the neonate and neonatal opioid withdrawal syndrome shortly after birth.

Neonatal opioid withdrawal syndrome presents as irritability, hyperactivity, abnormal sleep pattern, high pitched cry, tremor, vomiting, diarrhea and failure to gain weight. The onset, duration, and severity of neonatal opioid withdrawal syndrome vary based on the specific opioid used, duration of use, timing and amount of last maternal use, and rate of elimination of the drug by the newborn. Observe newborns for symptoms of neonatal opioid withdrawal syndrome and manage accordingly [see WARNINGS].

Labor and Delivery:

Opioids cross the placenta and may produce respiratory depression and psychophysiologic effects in neonates. An opioid antagonist, such as naloxone, must be available for reversal of opioid-induced respiratory depression in the neonate. Hydrocodone Bitartrate and Acetaminophen Tablets are not recommended for use in pregnant women during or immediately prior to labor, when other analgesic techniques are more appropriate.
Opioid analgesics, including Hydrocodone Bitartrate and Acetaminophen Tablets, can prolong labor through actions which temporarily reduce the strength, duration, and frequency of uterine contractions. However, this effect is not consistent and may be offset by an increased rate of cervical dilation, which tends to shorten labor. Monitor neonates exposed to opioid analgesics during labor for signs of excess sedation and respiratory depression.

Nursing Mothers:

Hydrocodone is present in human milk.

The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Hydrocodone Bitartrate and Acetaminophen Tablets and any potential adverse effects on the breastfed infant from Hydrocodone Bitartrate and Acetaminophen Tablets or from the underlying maternal condition.

Infants exposed to Hydrocodone Bitartrate and Acetaminophen Tablets through breast milk should be monitored for excess sedation and respiratory depression. Withdrawal symptoms can occur in breastfed infants when maternal administration of an opioid analgesic is stopped, or when breast-feeding is stopped.

Pediatric Use:

Safety and effectiveness of Hydrocodone Bitartrate and Acetaminophen Tablets in pediatric patients have not been established.

Geriatric Use:

Elderly patients (aged 65 years or older) may have increased sensitivity to Hydrocodone Bitartrate and Acetaminophen Tablets. In general, use caution when selecting a dosage for an elderly patient, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy.

Respiratory depression is the chief risk for elderly patients treated with opioids, and has occurred after large initial doses were administered to patients who were not opioid-tolerant or when opioids were co-administered with other agents that depress respiration. Titrate the dosage of Hydrocodone Bitartrate and Acetaminophen Tablets slowly in geriatric patients and follow closely for signs of central nervous system and respiratory depression [see WARNINGS].

Hydrocodone and acetaminophen are known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.

Hepatic Impairment
Patients with hepatic impairment may have higher plasma hydrocodone concentrations than those with normal function. Use a low initial dose of Hydrocodone Bitartrate and Acetaminophen Tablets in patients with hepatic impairment and follow closely for adverse events such as respiratory depression and sedation.

Renal Impairment
Patients with renal impairment may have higher plasma hydrocodone concentrations than those with normal function. Use a low initial dose Hydrocodone Bitartrate and Acetaminophen Tablets in patients with renal impairment and follow closely for adverse events such as respiratory depression and sedation.
