title: Effect of non-antihypertensive drugs on endothelial function in hypertensive subjects evaluated by flow-mediated vasodilation.
abstract: Hypertension (HTN) is a major risk factor for atherosclerosis. Flow-mediated vasodilation (FMD) is an ultrasonic method used to evaluate endothelial function, which is associated with HTN and related complications. We summarized clinical trials focusing on the effects of non-antihypertensive drugs on endothelial function, as evaluated by FMD, in patients with HTN. Hypercholesterolemic patients with HTN who used the cholesterol- lowering drugs HMG-CoA reductase inhibitors (statins) had improved FMD with a reduction in cholesterol levels and no significant change in blood pressure (BP). Non-diabetic patients with HTN who used the insulinsensitizing drug pioglitazone had improved FMD with a reduction in insulin resistance. Obese patients with HTN who used the anti-obesity drug orlistat had improved FMD with a reduction in BP and weight, and the improvement in FMD was correlated with weight reduction. Patients with HTN who used the selective cyclocxygenase-2 inhibitor celecoxib had improved FMD with no significant change in BP. Hypercholesterolemic patients with HTN who used aspirin added to a statin had improved FMD with a reduction in BP. Patients with HTN who used the advanced glycation endproduct crosslink breaker alagebrium had improved FMD with no significant change in BP. Postmenopausal women with HTN who used estrogen-replacement therapy had improved FMD. The possibility of improvement in FMD levels has, therefore, been suggested with several non-antihypertensive drugs. In addition to the direct effects of antihypertensive drugs on endothelial function, use of these non-antihypertensive drugs may give important insights into HTN management.
