{{/items}} {{^items}}Description
Doxazosin is a quinazoline-derivative that selectively antagonizes postsynaptic α1-adrenergic receptors. It may be used to mild to moderate hypertension and in the management of symptomatic benign prostatic hyperplasia (BPH). α1-Receptors mediate contraction and hypertrophic growth of smooth muscle cells. Antagonism of these receptors leads to smooth muscle relaxation in the peripheral vasculature and prostate gland.
Indication
For treatment and management of mild to moderate hypertension and urinary obstruction symptoms caused by BPH.
Mechanism of Action
Doxazosin acts by inhibiting the postsynaptic alpha(1)-adrenoceptors on vascular smooth muscle. This inhibits the vasoconstrictor effect of circulating and locally released catecholamines (epinephrine and norepinephrine), resulting in peripheral vasodilation.
