4 Drug and Medication Information
4.1 Drug Indication

For the treatment of moderate to severe hypertension.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Pargyline is a monoamine oxidase B (MAO-B) inhibitor with antihypertensive properties. Patients taking pargyline must avoid concurrent consumption of tyramine-containing foods such as bleu cheese and beer, as this can lead to a hypertensive crisis.


5.2 MeSH Pharmacological Classification

Antihypertensive Agents

Drugs used in the treatment of acute or chronic vascular HYPERTENSION regardless of pharmacological mechanism. Among the antihypertensive agents are DIURETICS; (especially DIURETICS, THIAZIDE); ADRENERGIC BETA-ANTAGONISTS; ADRENERGIC ALPHA-ANTAGONISTS; ANGIOTENSIN-CONVERTING ENZYME INHIBITORS; CALCIUM CHANNEL BLOCKERS; GANGLIONIC BLOCKERS; and VASODILATOR AGENTS. (See all compounds classified as Antihypertensive Agents.)


Monoamine Oxidase Inhibitors

A chemically heterogeneous group of drugs that have in common the ability to block oxidative deamination of naturally occurring monoamines. (From Gilman, et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed, p414) (See all compounds classified as Monoamine Oxidase Inhibitors.)


5.3 ATC Code

C - Cardiovascular system

C02 - Antihypertensives

C02K - Other antihypertensives

C02KC - Mao inhibitors

C02KC01 - Pargyline


5.4 Mechanism of Action

MAOIs act by inhibiting the activity of monoamine oxidase, thus preventing the breakdown of monoamine neurotransmitters and thereby increasing their availability. There are two isoforms of monoamine oxidase, MAO-A and MAO-B. MAO-A preferentially deaminates serotonin, melatonin, epinephrine and norepinephrine. MAO-B preferentially deaminates phenylethylamine and trace amines. Pargyline functions by inhibiting the metabolism of catecholamines and tyramine within presynaptic nerve terminals. Catecholamines cause general physiological changes that prepare the body for physical activity (fight-or-flight response). Some typical effects are increases in heart rate, blood pressure, blood glucose levels, and a general reaction of the sympathetic nervous system.
