            C:Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D:Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            Pharmacology

            Mechanism of Action

            Inhibits sterol transporter at brush border and, consequently, intestinal absorption of cholesterol, which in turn decreases delivery of cholesterol to the liver and reduces hepatic cholesterol stores

            Absorption

            Bioavailability: Variable

            Peak plasma time: 4-12 hr (parent drug); 1-2 hr (metabolite)

            Peak plasma concentration: 3.4-5.5 ng/mL (parent drug); 45-71 ng/mL (metabolite)

            Distribution

            Protein bound: >90%

            Metabolism

            Metabolized by glucuronide conjugation

            Metabolites: Ezetimibe-glucuronide (80-90%)

            Elimination

            Half-life: 22 hr

            Excretion: Bile (78%), urine (11%)
