Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds bile acids in the intestine, forming an insoluble complex that is excreted in feces, thereby preventing enterohepatic recirculation of bile acids and promoting hepatic conversion of cholesterol to bile acids, reducing serum LDL-cholesterol.
LEROCHOL is a selective inhibitor of intestinal bile acid transport, specifically the apical sodium-dependent bile acid transporter (ASBT), reducing bile acid reabsorption and increasing fecal bile acid excretion, thereby lowering serum LDL cholesterol.
4 g orally once or twice daily, increased gradually to 4 g 1-6 times daily; maintenance 4-24 g/day in divided doses.
Oral: 10 mg once daily, taken at bedtime without regard to meals.

Not applicable; cholestyramine is not absorbed systemically and has no plasma half-life; clinical effect duration reflects gastrointestinal transit time.
Terminal elimination half-life: 12-18 hours. Clinical context: Requires dose adjustment in severe hepatic impairment; no adjustment needed for renal impairment.
Primarily fecal as bile acid complex; <0.05% renal excretion of unchanged drug; negligible systemic absorption.
Primarily fecal (85%) as unchanged drug and metabolites via biliary excretion. Renal excretion accounts for 15%, mostly as glucuronide conjugates.
