|Abstract:||In this study, which was primarily designed to determine the lipid-lowering efficacy of pravastatin in the setting of background antihypertensive therapy with ACE inhibitors and calcium antagonists, we took the opportunity to examine whether pravastatin interacts with antihypertensive therapy to produce additional falls in blood pressure. This may help clarify the mechanism of action of pravastatin's rapid beneficial effects on cardiovascular morbidity. We treated 25 hypertensive hypercholesterolaemic patients with 12 weeks of either pravastatin or placebo in this double blind, placebo controlled parallel group study. Placebo treatment did not alter plasma lipids, whereas 12 weeks' treatment with pravastatin reduced total cholesterol by 27% (from 7.1 +/- 0.27 to 5.2 +/- 0.18, p < 0.001 compared with placebo) and low density lipoprotein cholesterol by 35% (from 4.9 +/- 0.36 to 3.2 +/- 0.17, p < 0.001). There were no changes in systolic or diastolic blood pressure either following 12 weeks' treatment or 3 weeks' withdrawal of pravastatin. Thus, pravastatin remains efficacious as a lipid lowering agent in the presence of antihypertensive therapy but does not enhance the blood pressure lowering action of these drugs. Therefore it is unlikely that blood pressure reduction is the mechanism by which pravastatin mediates its reported short term effects on cardiovascular morbidity.|
