Description

General description

Prazosin is a member of the class of α-adrenergic blockers.[1] It is considered as a peripheral vasodilator antihypertensive agent. Prazosin is a derivative of quinazoline.[2]

Application

Prazosin hydrochloride has been used:

• to block the α1adrenergic receptors that mediate sympathetic vasoconstriction in mice[3]
• as an α1-adrenoceptor blocker,administered intragastrically in rats[4]
• as a vasodilator,administered together with inuslin into the left ventricle of mice for the assessment of its effects on renal functions[5]

Biochem/physiol Actions

Peripheral α1-adrenoceptor antagonist; vasodilator. Prazosin can be used to treat chronic posttraumatic stress disorder (PTSD).[6] It plays a role in reducing blood pressure by relaxing blood vessels, hence used in the treatment of high blood pressure.[1]
