Gabazine (SR-95531) is a drug that acts as an antagonist at GABA_A receptors. It is used in scientific research and has no role in medicine, as it would be expected to produce convulsions if used in humans.^[1]

Close

Gabazine binds to the GABA recognition site of the receptor-channel complex and acts as an allosteric inhibitor of channel opening.^[2] The net effect is to reduce GABA-mediated synaptic inhibition by inhibiting chloride flux across the cell membrane, and thus inhibiting neuronal hyperpolarization. While phasic (synaptic) inhibition is gabazine-sensitive, tonic (extrasynaptic) inhibition is relatively gabazine-insensitive.^[3]

Gabazine has been found to bind to and antagonize α₄βδ subunit-containing GABA_A receptors, which may represent the GHB receptor.^[4]
