Abstract

Many drugs are claimed to be effective vasodilators which can improve blood flow in peripheral vascular disorders. Among them are noradrenaline antagonists such as tolazoline (Priscol - Ciba), azapetine (Ilidar - Roche) and phenoxybenzamine (Dibenyline - SKF), and drugs which act directly on the smooth muscle of blood vessels, such as isoxsuprine (Duvadilan - Crookes; Dilavase - Organon), nicotinyl alcohol (Ronicol - Roche), and cyclandelate (Cyclospasmol - Camden). Nicotinic acid, papaverine and ethyl alcohol are also used as vasodilators. Claims that cyclandelate and certain other drugs are indicated in the treatment of cerebrovascular disease will be discussed in a future issue.
