Patients with Coronary Heart Disease: In the IMPROVE-IT study (see Pharmacology: Pharmacodynamics: Clinical Studies under Actions), involving 18,144 patients treated with either VYTORIN 10/40 mg (n=9067; of whom 6% were uptitrated to VYTORIN 10/80 mg) or simvastatin 40 mg (n=9077; of whom 27% were uptitrated to simvastatin 80 mg), the safety profiles were similar during a median follow-up period of 6.0 years. Discontinuation rates due to adverse experiences were 10.6% for patients treated with VYTORIN and 10.1% for patients treated with simvastatin. The incidence of myopathy was 0.2% for VYTORIN and 0.1% for simvastatin, where myopathy was defined as unexplained muscle weakness or pain with a serum CK ≥10 times ULN or two consecutive observations of CK ≥5 and <10 times ULN. The incidence of rhabdomyolysis was 0.1% for VYTORIN and 0.2% for simvastatin, where rhabdomyolysis was defined as unexplained muscle weakness or pain with a serum CK ≥10 times ULN with evidence of renal injury, ≥5 X ULN and <10 X ULN on two consecutive occasions with evidence of renal injury or CK ≥10,000 IU/L without evidence of renal injury. The incidence of consecutive elevations of transaminases (≥3 X ULN) was 2.5% for VYTORIN and 2.3% for simvastatin. (See Precautions.) Gallbladder-related adverse effects were reported in 3.1% vs 3.5% of patients allocated to VYTORIN and simvastatin, respectively. The incidence of cholecystectomy hospitalizations was 1.5% in both treatment groups. Cancer (defined as any new malignancy) was diagnosed during the trial in 9.4% vs 9.5%, respectively.
Post-marketing Experience: The following additional adverse reactions have been reported in post-marketing use with VYTORIN or during clinical studies or post-marketing use with one of the individual components. The adverse reactions reported for VYTORIN are consistent with those previously reported with ezetimibe and/or simvastatin.
Investigations: liver function test abnormal.
Blood and lymphatic system disorders: thrombocytopenia; anemia.
Nervous system disorders: peripheral neuropathy; myasthenia gravis (see Myasthenia Gravis/Ocular Myasthenia under Precautions).
Eye disorders: ocular myasthenia (see Myasthenia Gravis/Ocular Myasthenia under Precautions).
Respiratory, thoracic and mediastinal disorders: cough; interstitial lung disease.
Gastrointestinal disorders: constipation; pancreatitis; gastritis.
Skin and subcutaneous tissue disorders: alopecia; hypersensitivity reactions, including rash, lichenoid drug eruptions, urticaria, anaphylaxis, angio-edema; erythema multiforme.
Musculoskeletal and connective tissue disorders: muscle cramps; myopathy/rhabdomyolysis (see Myopathy/Rhabdomyolysis under Precautions).
There have been very rare reports of immune-mediated necrotizing myopathy (IMNM), an autoimmune myopathy, associated with statin use. IMNM is clinically characterized by: persistent proximal muscle weakness and elevated serum creatine kinase, which persist despite discontinuation of statin treatment; muscle biopsy showing necrotizing myopathy without significant inflammation; improvement with immunosuppressive agents (see Myopathy/Rhabdomyolysis under Precautions).
Metabolism and nutrition disorders: decreased appetite.
Vascular disorders: hot flush; hypertension.
General disorders and administration site conditions: pain.
Hepato-biliary disorders: hepatitis/jaundice; fatal and non-fatal hepatic failure; cholelithiasis; cholecystitis.
Reproductive system and breast disorders: erectile dysfunction.
Psychiatric disorders: depression.
An apparent hypersensitivity syndrome has been reported rarely which has included some of the following features: angioedema, lupus-like syndrome, polymyalgia rheumatica, dermatomyositis, vasculitis, thrombocytopenia, eosinophilia, ESR increased, arthritis and arthralgia, urticaria, photosensitivity, fever, flushing, dyspnea and malaise.
There have been rare post marketing reports of cognitive impairment (e.g., memory loss, forgetfulness, amnesia, memory impairment, confusion) associated with statin use. These cognitive issues have been reported for all statins. The reports are generally nonserious, and reversible upon statin discontinuation, with variable times to symptom onset (1 day to years) and symptom resolution (median of 3 weeks).
Laboratory Values: In controlled clinical coadministration trials, the incidence of clinically important elevations in serum transaminases (ALT and/or AST ≥3 X ULN, consecutive) was 1.7% for patients treated with VYTORIN. These elevations were generally asymptomatic, not associated with cholestasis, and returned to baseline after discontinuation of therapy or with continued treatment (see Precautions).
Clinically important elevations of CK (≥10 X ULN) were seen in 0.2% of the patients treated with VYTORIN.
Increases in HbA1c and fasting serum glucose levels have been reported with statins, including simvastatin. The risk of hyperglycemia, however, is outweighed by the reduction in vascular risk with statins.
