GABA antagonist

From Wikipedia, the free encyclopedia

Jump to: navigation, search

GABA antagonists are drugs which inhibit the action of GABA. In general these drugs produce stimulant and convulsant effects, and are mainly used for counteracting overdoses of sedative drugs.

Examples include Bicuculline and Metrazol, and the benzodiazepine GABA_A receptor antagonist Flumazenil. Also thujone and muira puama may have properties of GABA_A receptor antagonism.
