    4 Pharmacology and Biochemistry
    4.1 MeSH Pharmacological Classification

    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.)

    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.)
