The clinical impact of comparative differences in lipid changes between products is not known. The dosage should be individualized according to the baseline LDL-C level and the patient’s response to treatment. The independent effect of lowering TG on the risk of coronary and cardiovascular morbidity and mortality has not been determined.

VYTORIN contains 2 active ingredients: ezetimibe and simvastatin. No incremental benefit of VYTORIN on cardiovascular morbidity and mortality over and above that demonstrated for simvastatin has been established.
VYTORIN is indicated as adjunctive therapy to diet for the reduction of elevated TOTAL-C, LDL-C, Apo B, TG, and
non–HDL-C, and to increase HDL-C in patients with primary (heterozygous familial and nonfamilial) hyperlipidemia or mixed hyperlipidemia when diet alone is not enough.
non–HDL-C, and to increase HDL-C in patients with primary (heterozygous familial and nonfamilial) hyperlipidemia or mixed hyperlipidemia when diet alone is not enough.
SELECTED CAUTIONARY INFORMATION
Liver: Due to the unknown effects of the increased exposure to ezetimibe in patients with moderate or severe hepatic impairment, VYTORIN is not recommended in these patients.
The incidence of consecutive elevations (>3 × ULN) in serum transaminases was 1.7% overall and appeared to be dose related, with an incidence of 2.6% for 10/80 mg. In long-term (48-week) extensions, which included both newly treated and previously treated patients, the incidence was 1.8% overall and 3.6% for 10/80 mg. These elevations were generally asymptomatic, not associated with cholestasis, and reversible whether treatment was maintained or discontinued.
Liver function tests should be performed at treatment initiation and thereafter when clinically indicated. Patients titrated to 10/80 mg should receive an additional test prior to titration, 3 months after titration, and periodically thereafter (eg, semiannually) during the first year. If an increase in AST or ALT of >3 × ULN persists, discontinue the drug.
In clinical trials, the most commonly reported side effects, regardless of cause, included headache (5.8%), increased ALT (3.7%), myalgia (3.6%), upper respiratory tract infection (3.6%), and diarrhea (2.8%).

Study Design: A multicenter, double-blind, randomized, active-controlled, 8-arm, parallel-group, 6-week, active-treatment study. Patients with hypercholesterolemia (N=1,902) who had not met their LDL-C goal as defined by NCEP ATP III were randomized to 1 of 8 treatment groups: VYTORIN 10/10, 10/20, 10/40, or 10/80 mg or atorvastatin 10, 20, 40, or 80 mg. The primary end point of the study was mean percent change in LDL-C from untreated baseline averaged across all doses studied.1
Median pooled baseline TG levels for VYTORIN and atorvastatin were 171 mg/dL and 167 mg/dL, respectively. Median baseline TG levels for VYTORIN 10/10 mg, atorvastatin 10 mg, VYTORIN 10/20 mg, atorvastatin 20 mg, VYTORIN 10/40 mg, atorvastatin 40 mg, VYTORIN 10/80 mg, and atorvastatin 80 mg were 174 mg/dL, 171 mg/dL, 167 mg/dL, 174 mg/dL, 172 mg/dL, 161 mg/dL, 170 mg/dL, and 166 mg/dL, respectively.1
