5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Tocolytic Agents

Drugs that prevent preterm labor and immature birth by suppressing uterine contractions (TOCOLYSIS). Agents used to delay premature uterine activity include magnesium sulfate, beta-mimetics, oxytocin antagonists, calcium channel inhibitors, and adrenergic beta-receptor agonists. The use of intravenous alcohol as a tocolytic is now obsolete. (See all compounds classified as Tocolytic Agents.)


Bronchodilator Agents

Agents that cause an increase in the expansion of a bronchus or bronchial tubes. (See all compounds classified as Bronchodilator Agents.)


Adrenergic beta-2 Receptor Agonists

Compounds bind to and activate ADRENERGIC BETA-2 RECEPTORS. (See all compounds classified as Adrenergic beta-2 Receptor Agonists.)


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.)
