Interactions between your drugs
triamcinolone colestipol
Applies to: Aristospan (triamcinolone) and colestipol
ADJUST DOSING INTERVAL: Concurrent administration of bile acid sequestrants may delay and/or decrease the absorption of oral corticosteroids. Bile acid sequestrants can bind certain drugs in the intestine to form an insoluble complex that is excreted in the feces. Reduced bioavailability of hydrocortisone has been reported during concomitant administration with cholestyramine and colestipol. It is not known whether the interaction occurs with other bile acid binding resins such as colesevelam or with corticosteroids other than hydrocortisone, but the possibility should be considered.
MANAGEMENT: Oral corticosteroids should be administered at least 1 hour before or 4 to 6 hours after a cholestyramine or colestipol dose, and at least 4 hours before a colesevelam dose.

Drug and food interactions
colestipol food
Applies to: colestipol
ADJUST DOSING INTERVAL: Bile acid sequestrants and the phosphate binder, sevelamer, can decrease the absorption of fat-soluble vitamins A, D, E, and K. In non-clinical safety studies, rats administered colesevelam at doses greater than 30-fold the projected human clinical dose developed hemorrhage in association with vitamin K deficiency. In a crossover study involving healthy subjects, coadministration of sevelamer with calcitriol resulted in a significant reduction in bioavailability for calcitriol (calcitriol with sevelamer vs calcitriol alone: AUC 137 pg*h/mL vs 318 pg*h/mL and Cmax 40.1 pg/mL vs 49.7 pg/mL, respectively).
MANAGEMENT: Oral vitamin supplements should be administered at least 4 hours before colesevelam and either 1 hour before or 4 to 6 hours after other bile acid sequestrants and sevelamer.
