FLAVORED COLESTID vs QUESTRAN LIGHT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Colestid (colestipol) is a bile acid sequestrant. It binds bile acids in the intestine, forming an insoluble complex that is excreted in feces. This reduces enterohepatic circulation of bile acids, leading to increased hepatic conversion of cholesterol to bile acids, thereby lowering serum low-density lipoprotein (LDL) cholesterol levels.
Binds bile acids in the intestine, forming an insoluble complex that is excreted in feces, thereby reducing enterohepatic circulation of bile acids and promoting conversion of cholesterol to bile acids in the liver.
5-30 grams orally daily, divided into 2-4 doses, starting at 5 grams once daily and increasing by 5 grams every 4-7 days as tolerated; taken with meals and mixed with at least 4-8 oz of liquid per dose.
4 grams (one packet or one level scoop) orally once or twice daily, with a maximum of 24 grams per day. Dose may be increased by 4 grams daily at weekly intervals as needed.

Not applicable due to non-absorbable resin; systemic absorption is negligible. Terminal half-life not defined.
Not applicable; cholesteryamine resin is not absorbed systemically; half-life refers to GI transit time (~2-4 hours).
Primarily fecal as insoluble complex (90-95%); <5% renal as glucuronide conjugate; minimal biliary elimination.
Primarily fecal (as resin-bound bile acids); less than 0.05% renally excreted unchanged.
