In Canada, it is marketed by Valeant as Lodalis. Colesevelam is indicated as an adjunct to diet and exercise to reduce elevated low-density lipoprotein cholesterol (LDL-C) in patients with primary hyperlipidemia as monotherapy and to improve glycemic control in adults with type 2 diabetes mellitus, including in combination with a statin. The expanded use of colesevelam in adults with type 2 diabetes mellitus is an example of drug repositioning. Colesevelam is one of the bile-acid sequestrants, which along with niacin and the statins, are the three main types of cholesterol-lowering agents. The statins are considered the first-line agents. This is because of the larger body of evidence supporting statins' ability to prevent cardiovascular disease, as well as the prominent side effects from the other two types, including bloating and constipation (bile-acid sequestrants) and skin flushing (niacin). These side effects often lead to low patient compliance.
