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.

The symptoms associated with benign prostatic hyperplasia BPH such as urinary frequency, nocturia, weak stream, hesitancy, and incomplete emptying are related to two components, anatomical static and functional dynamic. The static component is related to an increase in prostate size caused, in part, by a proliferation of smooth muscle cells in the prostatic stroma. However, the severity of BPH symptoms and the degree of urethral obstruction do not correlate well with the size of the prostate. The dynamic component of BPH is associated with an increase in smooth muscle tone in the prostate and bladder neck. The degree of tone in this area is mediated by the alpha 1 adrenoceptor, which is present in high density in the prostatic stroma, prostatic capsule, and bladder neck. Blockade of the alpha 1 receptor decreases urethral resistance and may relieve the BPH symptoms and improve urine flow. Doxazosin mesylate is a selective inhibitor of the alpha 1-subtype of alpha adrenergic receptors. In the human prostate, doxazosin mesylate antagonizes phenylephrine alpha 1 agonist-induced contractions, in vitro, and binds with high affinity to the alpha 1A adrenoceptor.
