Colesevelam is a bile acid sequestrant. Colesevelam is used with exercise and diet changes (restriction of cholesterol and fat intake) to reduce the amount of cholesterol and certain fatty substances in the blood. It works by binding bile acids in the intestine. Bile acids are made when cholesterol is broken down in the body. Removing these bile acids helps to lower blood cholesterol.

Dược Lực Học : Colesevelam is a high capacity bile-acid binding molecule. Colesevelam binds to bile acids in the intestine which reduces the amount of bile acids that are returned to the liver via enterohepatic circulation. Clinical studies have demonstrated that elevated levels of total cholesterol (total-C), LDL-C, and apolipoprotein B (Apo B, a protein associated with LDL-C) are associated with an increased risk of atherosclerosis in humans. Similarly, decreased levels of high-density lipoprotein cholesterol (HDL-C) are associated with the development of atherosclerosis. Epidemiological investigations have established that cardiovascular morbidity and mortality vary directly with the levels of total-C and LDL-C, and inversely with the level of HDL-C. The combination of colesevelam and an HMG-CoA reductase inhibitor is effective in further lowering serum total-C and LDL-C levels beyond that achieved by either agent alone.
Cơ Chế Tác Dụng : Colesevelam is a bile acid sequestrant. Colesevelam is used with exercise and diet changes (restriction of cholesterol and fat intake) to reduce the amount of cholesterol and certain fatty substances in the blood. It works by binding bile acids in the intestine. Bile acids are made when cholesterol is broken down in the body. Removing these bile acids helps to lower blood cholesterol. Colesevelam is a non-absorbed, lipid-lowering polymer that binds bile acids in the intestine, impeding their reabsorption. As the bile acid pool becomes depleted, the hepatic enzyme, cholesterol 7-(alpha)-hydroxylase, is upregulated, which increases the conversion of cholesterol to bile acids. This causes an increased demand for cholesterol in the liver cells, resulting in the dual effect of increasing transcription and activity of the cholesterol biosynthetic enzyme, hydroxymethyl-glutaryl-coenzyme A (HMG-CoA) reductase, and increasing the number of hepatic low-density lipoprotein (LDL) receptors. These compensatory effects result in increased clearance of LDL cholesterol (LDL-C) from the blood, resulting in decreased serum LDL-C levels. Serum triglyceride levels may increase or remain unchanged. The end result is increased clearance of LDL-cholesterol from the blood with decreased serum LDL-cholesterol.
Dược Động Học :
▧ Absorption :
Not hydrolyzed by digestive enzymes and is not absorbed.
▧ Protein binding :
Not applicable (not hydrolyzed by digestive enzymes and not absorbed).
▧ Metabolism :
Not applicable (not hydrolyzed by digestive enzymes and not absorbed).
▧ Route of Elimination :
Excretion: In 16 healthy volunteers, an average of 0.05% of administered radioactivity from a single 14C-labeled colesevelam hydrochloride dose was excreted in the urine.
Độc Tính : Symptoms of overdose may include eye irritation, constipation, abdominal cramps, nausea, vomiting, diarrhea, and hypersensitivity. However, as colesevelam is not absorbed, the risk of systemic toxicity is low. Doses in excess of 4.5 g per day have not been tested.
Chỉ Định : For use, alone or in combination with an HMG-CoA reductase inhibitor, as adjunctive therapy to diet and exercise for the reduction of elevated LDL cholesterol in patients with primary hypercholesterolemia (Fredrickson Type IIa).
Tương Tác Thuốc :
  • Alfacalcidol Bile acid sequestrants such as colesevelam may decrease the serum concentration of Vitamin D Analogs. More specifically, bile acid sequestrants may impair absorption of Vitamin D Analogs. Avoid concomitant administration of vitamin D analogs and bile acid sequestrants (e.g., cholestyramine). Monitor plasma calcium concentrations in patients receiving combined therapy with these agents. This is particularly important in patients receiving higher doses of a bile acid sequestant (i.e., 30 g/day or more of cholestyramine or equivalent) or in patients experiencing bile acid sequestrant-induced steatorrhea. Specific recommendations regarding the separation of administration of these agents are not defined; however, it would seem prudent to separate the administration of these agents by several hours to minimize the potential risk of interaction. Similar precautions do not apply to parenterally administered vitamin D analogs.
  • Amiodarone Bile Acid Sequestrants may decrease the bioavailability of Amiodarone. Consider alternative antilipemic agent. The risk of subtherapeutic amiodarone serum concentrations when such is being used for the treatment of malignant arrhythmias can be very large.
