Tương tác
May reduce the absorption of fat-soluble vitamins A, D, E, and K. May diminish the anticoagulant effect of warfarin. May reduce the exposures of ciclosporin, olmesartan, phenytoin, levothyroxine, oral contraceptives (e.g. norethindrone, ethinylestradiol), glipizide, glimepiride, and glibenclamide. Concurrent use with the extended-release tab of metformin may increase exposure of metformin. May result in increased triglyceride levels with insulin, thiazolidinediones (e.g. pioglitazone), or sulfonylureas.

Tác dụng
Description:
Mechanism of Action: Colesevelam is a nonabsorbable hydrogel that binds with bile acids in the intestine to form a nonabsorbable complex that is excreted in the faeces. This results in increased conversion of cholesterol to bile acids in the liver causing an increased demand for cholesterol in liver cells leading to a compensatory increase in hepatic uptake of circulating LDL-C. Additionally, its mechanism of action for improving glycaemic control in type 2 diabetes mellitus is unknown. Onset: Lipid-lowering effect: Approx 2 weeks. Reduction of HbA1c: 4-6 weeks. Pharmacokinetics: Absorption: Not absorbed from the gastrointestinal tract. Excretion: Via urine (0.05%). |
