The influence of cimetidine and ranitidine on the plasma lipid pattern

The influence of H2-receptor antagonist drugs on the plasma lipid pattern has been studied prospectively in 51 patients treated with cimetidine (26 patients) or ranitidine (25 patients) for gastroenterological diseases. Total and HDL cholesterol and total triglycerides have been measured. Ranitidine did not influence the investigated parameters, while cimetidine produced a significant increase in the HDL cholesterol serum concentration (P = 0.008).
