Type IIa hyperlipoproteinaemia. An evaluation of four therapeutic regimens.

The cholesterol-lowering effect of clofibrate (Ciba-SU13437) cholestyramine and the combination of clofibrate and cholestyramine is studied in 19 subjects with type lla hyperlipoproteinaemia, over a 20-week period. Each regimen is evaluated in terms of total cholesterol-lowering effect, cholesterol-lowering effect at 4, 8 and 16 weeks of therapy, and the incidence of side-effects. Cholestyramine is identified as the agent of choice in the management of this disorder and recommendations for its optimal utilisation are put forward.
