1. Bile acid sequestrants such as colestipol are effective lipid lowering agents but have a poor reputation for tolerability particularly when administered at the originally recommended doses. We have investigated a low dosage regimen with varying dosage intervals in order to assess efficacy and tolerability. 2. This double‐blind, placebo controlled, parallel group study was conducted to investigate the effect of varying administration schedules of colestipol (10 g daily), against placebo in reducing LDL cholesterol levels in patients with moderate hypercholesterolaemia on the American Heart Association step 1 diet. 3. Colestipol or matched placebo, was administered as 5 g twice daily (COL am/pm) or 10 g once daily in the morning (COL am) or evening (COL pm) at fixed times with meals. 4. All 98 patients who entered the initial 16 week dietary phase, subsequently entered the 12 week active treatment phase and were randomised to placebo or active treatment and to one of the three treatment schedules. Fasting lipid profiles were performed every 4 weeks during both phases. 5. All active treatments significantly reduced LDL and total cholesterol compared with placebo (COL am: 17% and 10%, COL pm: 18% and 10%, COL am/pm: 19% and 12% (P = 0.0001)). HDL cholesterol rose significantly with COL am (5% (P = 0.021)) and COL am/pm (7% (P = 0.002)) when compared with placebo while a marginal increase was seen with COL pm (4% (P = 0.063)). Colestipol tended to increase serum triglyceride concentrations but the changes were not significant.(ABSTRACT TRUNCATED AT 250 WORDS)
