5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Anticonvulsants

Drugs used to prevent SEIZURES or reduce their severity. (See all compounds classified as Anticonvulsants.)


Antimanic Agents

Agents that are used to treat bipolar disorders or mania associated with other affective disorders. (See all compounds classified as Antimanic Agents.)


Enzyme Inhibitors

Compounds or agents that combine with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction. (See all compounds classified as Enzyme Inhibitors.)


GABA Agents

Substances used for their pharmacological actions on GABAergic systems. GABAergic agents include agonists, antagonists, degradation or uptake inhibitors, depleters, precursors, and modulators of receptor function. (See all compounds classified as GABA Agents.)
