Ezetimibe

Statinprescriptionoral · inferred

Selective inhibitor of intestinal cholesterol absorption via NPC1L1, lowering LDL-C ~15-20% as monotherapy and additively with statins. Undergoes enterohepatic recirculation producing a long effective half-life of ~22 hours. Standard dose 10 mg once daily. IMPROVE-IT established CV event reduction when added to statin therapy post-ACS.

Projected serum levels — 10 mg, once daily

Ezetimibe modeled serum levels with a loading dose of 18.5 mg, then 10 mg once daily The first dose is larger so levels approach steady state faster. 0 2.5 5 7.5 10 Day 0 Day 4 Day 8 Day 11 Day 15 Time on a regular schedule

Maintenance schedule: 10 mg once daily (oral).

Loading schedule: 18.5 mg on day 1, then 10 mg once daily — reaching therapeutic levels sooner.

Modeled steady state after ~2 days: peak ≈ 6.2 mg, trough ≈ 3.0 mg body load. Population-based estimate over 15 days for a 10 mg dose at a 70 kg reference body mass — the interactive app scales curves to your doses, timing, and body mass.
