5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Adrenergic beta-Antagonists

Drugs that bind to but do not activate beta-adrenergic receptors thereby blocking the actions of beta-adrenergic agonists. Adrenergic beta-antagonists are used for treatment of hypertension, cardiac arrhythmias, angina pectoris, glaucoma, migraine headaches, and anxiety. (See all compounds classified as Adrenergic beta-Antagonists.)


Sympathomimetics

Drugs that mimic the effects of stimulating postganglionic adrenergic sympathetic nerves. Included here are drugs that directly stimulate adrenergic receptors and drugs that act indirectly by provoking the release of adrenergic transmitters. (See all compounds classified as Sympathomimetics.)


Adrenergic alpha-1 Receptor Antagonists

Drugs that bind to and block the activation of ADRENERGIC ALPHA-1 RECEPTORS. (See all compounds classified as Adrenergic alpha-1 Receptor Antagonists.)


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.)
