5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Adrenergic alpha-1 Receptor Agonists

Compounds that bind to and activate ADRENERGIC ALPHA-1 RECEPTORS. (See all compounds classified as Adrenergic alpha-1 Receptor Agonists.)


Analgesics, Non-Narcotic

A subclass of analgesic agents that typically do not bind to OPIOID RECEPTORS and are not addictive. Many non-narcotic analgesics are offered as NONPRESCRIPTION DRUGS. (See all compounds classified as Analgesics, Non-Narcotic.)


Oxytocics

Drugs that stimulate contraction of the myometrium. They are used to induce LABOR, OBSTETRIC at term, to prevent or control postpartum or postabortion hemorrhage, and to assess fetal status in high risk pregnancies. They may also be used alone or with other drugs to induce abortions (ABORTIFACIENTS). Oxytocics used clinically include the neurohypophyseal hormone OXYTOCIN and certain prostaglandins and ergot alkaloids. (From AMA Drug Evaluations, 1994, p1157) (See all compounds classified as Oxytocics.)


Serotonin Receptor Agonists

Endogenous compounds and drugs that bind to and activate SEROTONIN RECEPTORS. Many serotonin receptor agonists are used as ANTIDEPRESSANTS; ANXIOLYTICS; and in the treatment of MIGRAINE DISORDERS. (See all compounds classified as Serotonin Receptor Agonists.)


Vasoconstrictor Agents

Drugs used to cause constriction of the blood vessels. (See all compounds classified as Vasoconstrictor Agents.)
