5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Antidepressive Agents

Mood-stimulating drugs used primarily in the treatment of affective disorders and related conditions. Several MONOAMINE OXIDASE INHIBITORS are useful as antidepressants apparently as a long-term consequence of their modulation of catecholamine levels. The tricyclic compounds useful as antidepressive agents (ANTIDEPRESSIVE AGENTS, TRICYCLIC) also appear to act through brain catecholamine systems. A third group (ANTIDEPRESSIVE AGENTS, SECOND-GENERATION) is a diverse group of drugs including some that act specifically on serotonergic systems. (See all compounds classified as Antidepressive Agents.)


Selective Serotonin Reuptake Inhibitors

Compounds that specifically inhibit the reuptake of serotonin in the brain. (See all compounds classified as Selective Serotonin Reuptake Inhibitors.)


Serotonin 5-HT1 Receptor Agonists

Endogenous compounds and drugs that specifically stimulate SEROTONIN 5-HT1 RECEPTORS. Included under this heading are agonists for one or more of the specific 5-HT1 receptor subtypes. (See all compounds classified as Serotonin 5-HT1 Receptor Agonists.)
