    Abstract

    To assess the effect of cimetidine and ranitidine on high density lipoprotein (HDL) cholesterol concentration two groups of eight patients with duodenal ulcer or oesophagitis matched for age, sex, and cigarette consumption were given either cimetidine 1 g daily or ranitidine 300 mg daily for one month. There was no significant change in the cholesterol content of HDL and its subfraction HDL3 after treatment with ranitidine or cimetidine, or in the cholesterol content of the subfraction HDL2 after treatment with ranitidine; the HDL2 cholesterol concentration was, however, significantly increased after treatment with cimetidine. Further studies are being undertaken to establish the mechanism of this effect.
