Doxazosin Mesylate is the mesylate salt form of doxazosin, a quinazoline compound with smooth muscle relaxing activity. Doxazosin mesylate selectively antagonizes alpha-1-adrenergic receptors in smooth muscle of the bladder neck and prostate, thereby relaxing the smooth muscle and decreasing the obstruction and urethral resistance seen with benign prostate hyperplasia (BPH). This may improve BPH symptoms. This agent also blocks alpha-1-adrenergic receptors in peripheral vascular smooth muscle, which leads to vasodilatation and a subsequent decrease in peripheral vascular resistance.

Non-Human Toxicity Excerpts

/LABORATORY ANIMALS: Developmental or Reproductive Toxicity/ Studies in perinatal and postnatal rats given 40 or 50 mg/kg per day of doxazosin revealed evidence of delayed postnatal development manifested by slower body weight gain and slightly later appearance of anatomical features and reflexes. /Salt not specified/

Antidote and Emergency Treatment

Treatment of overdose: Treatment of circulatory failure by placing the patient the supine position and elevating the legs is most important; if shock is present, additional measures are necessary. Volume expanders may be used to treat shock, followed, if necessary, by administration of a vasopressor. Symptomatic, supportive treatment and monitoring of fluid and electrolyte status.
