Abstract
Objective: Hypercholesterolaemia is a major risk factor for atherosclerosis and coronary heart disease. Treatment with lipid lowering agents reduces the risk of vascular events. Colesevelam is a novel bile acid sequestrant (BAS) indicated for the treatment of hypercholesterolaemia, either as monotherapy or in combination with statins. Scope: This article reviews the efficacy, tolerability and safety of colesevelam in clinical practice. The literature search was based on a PubMed search up to January 2008. Findings: Colesevelam, used alone or in combination with other hypolipidaemic agents (statins, ezetimibe and fenofibrate), has an overall favourable effect on lipid profile. Specifically, colesevelam reduces total and low-density lipoprotein cholesterol (LDL-C) and apolipoprotein B levels and increases high-density lipoprotein cholesterol and apolipoprotein AI. However, colesevelam may slightly raise triglyceride levels. Colesevelam can improve glycaemic control in diabetic patients. Moreover, it may have anti-inflammatory properties, as it can reduce high sensitivity C-reactive protein concentration. Colesevelam almost lacks the intense side effects of previously used BASs, thus resulting in better patient compliance. However, the dose regimen consisting of up to 7 tablets/day and high cost may limit its use. Conclusions: Colesevelam is a safe alternative for those intolerant to other lipid lowering medication. This BAS also provides an option for patients who do not reach their LDL-C goal despite treatment with a statin.
