description -alfuzosin (inn provided as the hydrochloride salt) is an alpha-adrenergic blocker used to treat benign prostatic hyperplasia - -indication : -for the reduction of urinary obstruction and relief of associated manifestations (eg. sensation of incomplete bladder emptying or straining urgency interrupted or weak stream) in patients with symptomatic beningn prostatic hyperplasia. - -dosage: -the recommended dose is 2.5 mg 3 times/day. max: 10 mg/day. - -mechanism of action: -alfuzosin is a non-subtype specific alpha(1)-adrenergic blocking agent that exhibits selectivity for alpha(1)-adrenergic receptors in the lower urinary tract. inhibition of these adrenoreceptors leads to the relaxation of smooth muscle in the bladder neck and prostate resulting in the improvement in urine flow and a reduction in symptoms in benign prostate hyperplasia. alfuzosin also inhibits the vasoconstrictor effect of circulating and locally released catecholamines (epinephrine and norepinephrine)
