5 Pharmacology and Biochemistry

5.1 MeSH Pharmacological Classification

Abortifacient Agents, Nonsteroidal

Non-steroidal chemical compounds with abortifacient activity. (See all compounds classified as Abortifacient Agents, Nonsteroidal.)

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.)

5.2 ATC Code

G - Genito urinary system and sex hormones

G02 - Other gynecologicals

G02A - Uterotonics

G02AD - Prostaglandins
