Product Elements:
Phenoxybenzamine hydrochloride phenoxybenzamine hydrochloride phenoxybenzamine hydrochloride phenoxybenzamine lactose talc scarlet trans par;260
Drug Interactions:
Drug interactions 2 phenoxybenzamine hydrochloride may interact with compounds that stimulate both alpha- and beta- adrenergic receptors (i.e., epinephrine) to produce an exaggerated hypotensive response and tachycardia. ( see warnings . ) phenoxybenzamine hydrochloride blocks hyperthermia production by levarterenol, and blocks hypothermia production by reserpine.
Indications and Usage:
Indications and usage phenoxybenzamine hydrochloride capsules, usp is indicated in the treatment of pheochromocytoma, to control episodes of hypertension and sweating. if tachycardia is excessive, it may be necessary to use a beta -blocking agent concomitantly.
Warnings:
Warnings phenoxybenzamine hydrochloride -induced alpha -adrenergic blockade leaves beta -adrenergic receptors unopposed. compounds that stimulate both types of receptors may, therefore, produce an exaggerated hypotensive response and tachycardia.
General Precautions:
General administer with caution in patients with marked cerebral or coronary arteriosclerosis or renal damage. adrenergic blocking effect may aggravate symptoms of respiratory infections.
Dosage and Administration:
Dosage and administration the dosage should be adjusted to fit the needs of each patient. small initial doses should be slowly increased until the desired effect is obtained or the side effects from blockade become troublesome. after each increase, the patient should be observed on that level before instituting another increase . the dosage should be carried to a point where symptomatic relief and/or objective improvement are obtained, but not so high that the side effects from blockade become troublesome. initially, 10 mg of phenoxybenzamine hydrochloride twice a day. dosage should be increased every other day, usually to 20 to 40 mg 2 or 3 times a day, until an optimal dosage is obtained, as judged by blood pressure control. long-term use of phenoxybenzamine is not recommended ( see precautions carciongenesis and mutagenesis )
Contraindications:
Contraindications conditions where a fall in blood pressure may be undesirable; hypersensitivity to the drug or any of its components.
Adverse Reactions:
Adverse reactions the following adverse reactions have been observed, but there are insufficient data to support an estimate of their frequency. autonomic nervous system*: postural hypotension, tachycardia, inhibition of ejaculation, nasal congestion, miosis. *these so-called "side effects" are actually evidence of adrenergic blockade and vary according to the degree of blockade. miscellaneous: gastrointestinal irritation, drowsiness, fatigue.
Drug Interactions:
Drug interactions 2 phenoxybenzamine hydrochloride may interact with compounds that stimulate both alpha- and beta- adrenergic receptors (i.e., epinephrine) to produce an exaggerated hypotensive response and tachycardia. ( see warnings . ) phenoxybenzamine hydrochloride blocks hyperthermia production by levarterenol, and blocks hypothermia production by reserpine.
Use in Pregnancy:
Pregnancy - teratogenic effects - pregnancy category c adequate reproductive studies in animals have not been performed with phenoxybenzamine hydrochloride. it is also not known whether phenoxybenzamine hydrochloride can cause fetal harm when administered to a pregnant woman. phenoxybenzamine hydrochloride should be given to a pregnant woman only if clearly needed. â
Pediatric Use:
Pediatric use safety and effectiveness in pediatric patients have not been established.
Overdosage:
Overdosage symptoms-these are largely the result of blocking of the sympathetic nervous system and of the circulating epinephrine. they may include postural hypotension, resulting in dizziness or fainting; tachycardia, particularly postural; vomiting; lethargy; shock.
Description:
Description each phenoxybenzamine hydrochloride capsule, usp contains 10 mg of phenoxybenzamine hydrochloride, usp. inactive ingredients consist of lactose anhydrous and talc. phenoxybenzamine hydrochloride is n -(2-chloroethyl)- n -(1-methyl-2-phenoxyethyl) benzylamine hydrochloride: phenoxybenzamine hydrochloride is a white solid crystalline powder with a molecular weight of 340.3, which melts between 136° and 141°c. it is freely soluble in methanol, soluble in acetone, insoluble in ethyl acetate. usp organic impurities test pending. phenoxy benzamine
Clinical Pharmacology:
Clinical pharmacology phenoxybenzamine hydrochloride is a long-acting, adrenergic, alpha -receptor-blocking agent, which can produce and maintain "chemical sympathectomy" by oral administration. 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. twenty to 30 percent of orally administered phenoxybenzamine appears to be absorbed in the active form.¹ the half-life of orally administered phenoxybenzamine hydrochloride is not known; however, the half-life of intravenously administered drug is approximately 24 hours. demonstrable effects with intravenous administration persist for at least 3 to 4 days, and the effects of daily administration are cumulative for nearly a week.¹
Carcinogenesis and Mutagenesis and Impairment of Fertility:
Carcinogenesis and mutagenesis case reports of carcinoma in humans after long-term treatment with phenoxybenzamine have been reported. hence long-term use of phenoxybenzamine is not recommended 3, 4 . carefully weigh the benefits and risks before prescribing this drug. phenoxybenzamine hydrochloride showed in vitro mutagenic activity in the ames test and mouse lymphoma assay; it did not show mutagenic activity in vivo in the micronucleus test in mice. in rats and mice, repeated intraperitoneal administration of phenoxybenzamine hydrochloride (three times per week for up to 52 weeks) resulted in peritoneal sarcomas. chronic oral dosing in rats (for up to 2 years) produced malignant tumors of the small intestine and non-glandular stomach, as well as ulcerative and/or erosive gastritis of the glandular stomach. whereas squamous cell carcinomas of the non-glandular stomach were observed at all tested doses of phenoxybenzamine hydrochloride, there was a no-observed-effect-level of 10 mg/kg
