Benzazoline Uses, Dosage, Side Effects and more

A vasodilator that apparently has direct actions on blood vessels and also increases cardiac output. Benzazoline can interact to some degree with histamine, adrenergic, and cholinergic receptors, but the mechanisms of its therapeutic effects are not clear. It is used in treatment of persistent pulmonary hypertension of the newborn.

Benzazoline is a pulmonary vasodilator indicated used to decrease pulmonary vascular resistance (PVR) in persistent pulmonary hypertension of the newborn (PPHN).

How Benzazoline works

Vasodilation by means of a direct effect on peripheral vascular smooth muscle and indirect effects produced, in part, by release of endogenous histamine; tolazoline has moderate alpha-adrenergic blocking activity and has histamine agonist activity. Benzazoline usually reduces pulmonary arterial pressure and vascular resistance.
