Vasodilators（中文： 血管擴張劑）

Vasodilator is a broad term applied to drugs that produce dilatation of blood vessels.

Direct-acting vasodilators act predominantly on the arterioles reducing peripheral resistance and producing a fall in blood pressure. Their main use is in hypertension, although other drugs are generally preferred. Some of them are used in hypertensive crises.

• Hydralazine

Other vasodilators may be used for ischaemic heart disease.

• Trimetazidine

Vasodilators are also used for cerebral and peripheral vascular disorders. Some of these are now thought to improve microcirculatory flow disturbances by altering the rheological properties of blood or tissue metabolism.

• Naftidrofuryl
• Pentoxifylline
