Ciprofibrate--a profile.

The cornerstone of management in hyperlipidaemia is dietary and lifestyle therapy. Nonetheless, a proportion of patients will require drug therapy. Of the currently available choices, statins are of obvious value for raised cholesterol and low dose resins have a place in treating moderate hypercholesterolaemia. There is also an important role for the fibrates, particularly for modifying the hypertriglyceridaemic state and hence influencing low density lipoprotein (LDL) metabolism. Ciprofibrate is a compound newly introduced into the United Kingdom which shares many pharmacokinetic properties with other fibrates. Time to maximum serum concentration is about one hour and the long elimination half life (80 hours) permits once daily dosing. After a 12 week treatment period in Type II patients, LDL cholesterol was reduced by 24%. More recent work has shown a fall among Type IIa patients of 29% in LDL cholesterol with an increase in HDL cholesterol when ciprofibrate was given at 200 mg/day. A triglyceride reduction of 42% was recorded in Type IIb patients. Favourable effects have been described at 5 years of follow up for patients with Type IIa, Type IIb and Type IV patterns. Effects on clotting parameters are favourable and there is no significant long-term effect on biliary cholesterol saturation. In addition, no structural changes were observed in a small number of biopsies from treated patient liver. Side effects and contraindications are as for other fibrates. Ciprofibrate seems to be a valuable addition to drug therapy for the management of a variety of dyslipidaemias.
