The mechanism of action of Cardura is selective blockade of the alpha 1 postjunctional subtype of adrenergic receptors. Studies in normal human subjects have shown that doxazosin competitively antagonized the pressor effects of phenylephrine an alpha 1 agonist and the systolic pressor effect of norepinephrine. Doxazosin and prazosin have similar abilities to antagonize phenylephrine. The antihypertensive effect of Cardura results from a decrease in systemic vascular resistance. The parent compound doxazosin is primarily responsible for the antihypertensive activity. The low plasma concentrations of known active and inactive metabolites of doxazosin 2-piperazinyl, 6'- and 7'-hydroxy and 6- and 7-O-desmethyl compounds compared to parent drug indicate that the contribution of even the most potent compound 6'-hydroxy to the antihypertensive effect of doxazosin in man is probably small.
