5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Antidepressive Agents, Tricyclic

Substances that contain a fused three-ring moiety and are used in the treatment of depression. These drugs block the uptake of norepinephrine and serotonin into axon terminals and may block some subtypes of serotonin, adrenergic, and histamine receptors. However, the mechanism of their antidepressant effects is not clear because the therapeutic effects usually take weeks to develop and may reflect compensatory changes in the central nervous system. (See all compounds classified as Antidepressive Agents, Tricyclic.)


Adrenergic Uptake Inhibitors

Drugs that block the transport of adrenergic transmitters into axon terminals or into storage vesicles within terminals. The tricyclic antidepressants (ANTIDEPRESSIVE AGENTS, TRICYCLIC) and amphetamines are among the therapeutically important drugs that may act via inhibition of adrenergic transport. Many of these drugs also block transport of serotonin. (See all compounds classified as Adrenergic Uptake Inhibitors.)
