Description and Uses

Phenoxybenzamine hydrochloride (dibenzyline) is an orally effective, long-acting non-selective (alpha1 and alpha2) alpha-adrenoceptor blocking agent. It is used for the control of episodes of hypertension associated withpheochromocytoma. It literally produces a "chemical sympathectomy". It increases blood flow to the skin, mucosa and abdominal viscera, and lowers both supine and erect blood pressures. It has no effect on the parasympathetic system. The initialdose is 10 mg/day, increased by 10 mg every 4 days till the desired response is attained.The usual dosage range is 20-60mg/day.

Phenoxybenzamine is used in treating pheochromocytoma, swelling of the medullary layer of the adrenal glands, during which a large quantity of epinephrine is produced, which leads to a significant elevation of blood pressure.
