6 ADVERSE REACTIONS The following serious adverse reactions are discussed in greater detail in other sections of the label:

Rhabdomyolysis and myopathy [ see Warnings and Precautions ( 5.1 ) ]

Liver enzyme abnormalities [ see Warnings and Precautions ( 5.3 ) ]

Common (incidence ≥ 2% and greater than placebo) adverse reactions in clinical trials: headache, increased ALT, myalgia, upper respiratory tract infection, and diarrhea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Dr. Reddy’s Laboratories, Inc. at 1-888-375-3784 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Ezetimibe and Simvastatin Tablets 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. In the ezetimibe and simvastatin tablet placebo-controlled clinical trials database of 1,420 patients (age range 20 to 83 years, 52% women, 87% Caucasians, 3% Blacks, 5% Hispanics, 3% Asians) with a median treatment duration of 27 weeks, 5% of patients on ezetimibe and simvastatin tablets and 2.2% of patients on placebo discontinued due to adverse reactions. The most common adverse reactions in the group treated with ezetimibe and simvastatin tablets that led to treatment discontinuation and occurred at a rate greater than placebo were:

Increased ALT (0.9%)

Myalgia (0.6%)

Increased AST (0.4%)

Back pain (0.4%) The most commonly reported adverse reactions (incidence ≥ 2% and greater than placebo) in controlled clinical trials were: headache (5.8%), increased ALT (3.7%), myalgia (3.6%), upper respiratory tract infection (3.6%), and diarrhea (2.8%). Ezetimibe and simvastatin tablets have been evaluated for safety in more than 10,189 patients in clinical trials. Table 2 summarizes the frequency of clinical adverse reactions reported in ≥ 2% of patients treated with ezetimibe and simvastatin tablets (n = 1,420) and at an incidence greater than placebo, regardless of causality assessment, from four placebo-controlled trials.

Includes two placebo-controlled combination studies in which the active ingredients equivalent to ezetimibe and simvastatin tablets were coadministered and two placebo-controlled studies in which ezetimibe and simvastatin tablets were administered. 2 . All doses. Study of Heart and Renal Protection In SHARP, 9,270 patients were allocated to ezetimibe and simvastatin tablets 10 mg/20 mg daily (n = 4,650) or placebo (n = 4,620) for a median follow-up period of 4.9 years. The proportion of patients who permanently discontinued study treatment as a result of either an adverse event or abnormal safety blood result was 10.4% vs. 9.8% among patients allocated to ezetimibe and simvastatin and placebo, respectively. Comparing those allocated to ezetimibe and simvastatin vs. placebo, the incidence of myopathy (defined as unexplained muscle weakness or pain with a serum CK > 10 times ULN) was 0.2% vs. 0.1% and the incidence of rhabdomyolysis (defined as myopathy with a CK > 40 times ULN) was 0.09% vs. 0.02%, respectively. Consecutive elevations of transaminases (> 3 X ULN) occurred in 0.7% vs. 0.6%, respectively. Patients were asked about the occurrence of unexplained muscle pain or weakness at each study visit: 21.5% vs. 20.9% patients ever reported muscle symptoms in the ezetimibe and simvastatin and placebo groups, respectively. Cancer was diagnosed during the trial in 9.4% vs. 9.5% of patients assigned to ezetimibe and simvastatin and placebo, respectively. Ezetimibe Other adverse reactions reported with ezetimibe in placebo-controlled studies, regardless of causality assessment: Musculoskeletal system disorders: arthralgia; Infections and infestations: sinusitis; Body as a whole – general disorders: fatigue. Simvastatin In a clinical trial in which 12,064 patients with a history of myocardial infarction were treated with simvastatin (mean follow-up 6.7 years), the incidence of myopathy (defined as unexplained muscle weakness or pain with a serum creatine kinase [CK] > 10 times upper limit of normal [ULN]) in patients on 80 mg/day was approximately 0.9% compared with 0.02% for patients on 20 mg/day. The incidence of rhabdomyolysis...
