Colesevelam, a bile acid sequestrant used in the treatment of patients with hypercholesterolemia, is a lipid-lowering polymer that has high affinity for bile acids. In animals colesevelam was not systemically absorbed after oral administration and was rapidly eliminated via the gastrointestinal tract. Colesevelam did not alter the serum concentrations or pharmacokinetic properties of drugs from several different classes in healthy volunteers. Colesevelam administered orally in patients with primary hypercholesterolemia significantly reduced serum levels of low density lipoprotein (LDL)-cholesterol and total cholesterol. This lipid-lowering activity was sustained during short (6 weeks) and longer term (24 weeks) treatment. Combination therapy with colesevelam plus hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (lovastatin, simvastatin or atorvastatin) was associated with additive reductions in serum levels of LDL-cholesterol and total cholesterol, relative to either agent alone. Colesevelam treatment was well tolerated and lacked severe gastrointestinal adverse events typical of other bile acid sequestrants (bloating, flatulence, heartburn and nausea). The most frequently reported adverse events were constipation and dyspepsia. In humans colesevelam did not induce clinically significant changes in serum levels of vitamins, coagulation parameters or liver enzymes.

The bile acid sequestrant, colesevelam hydrochloride, is approved for glycemic control in adults with type 2 diabetes. In three double-masked, placebo-controlled studies, colesevelam hydrochloride 3.75 g/day demonstrated its glycemic-lowering properties when added to existing metformin-, insulin-, or sulfonylurea-based therapy in adults with inadequately controlled type 2 diabetes. This was a 52-week open-label extension study conducted at 63 sites in the United States and one site in Mexico to further evaluate the safety and tolerability of colesevelam hydrochloride in subjects with type 2 diabetes. All subjects who completed the three double-masked, placebo-controlled studies were eligible to enroll in this open-label extension. In total, 509 subjects enrolled and received open-label colesevelam hydrochloride 3.75 g/day for 52 weeks. Safety and tolerability of colesevelam hydrochloride was evaluated by the incidence and severity of adverse events. In total, 360 subjects (70.7%) completed the extension. Of the safety population, 361 subjects (70.9%) experienced an adverse event, most (88.1%) being mild or moderate in severity. Fifty-six adverse events (11.0%) were drug-related; the most frequent drug-related adverse events were constipation and dyspepsia. Thirty-five subjects (6.9%) discontinued due to an adverse event. Fifty-four subjects (10.6%) experienced a serious adverse event; only one was considered drug-related (diverticulitis). Seventeen subjects (3.3%) experienced hypoglycemia; most episodes were mild or moderate in severity. Glycemic improvements with colesevelam hydrochloride were seen without change in weight over 52 weeks (0.2 kg mean reduction from baseline). Colesevelam hydrochloride was safe and well-tolerated as long-term therapy for patients with type 2 diabetes.
