γ-Aminobutyric acid (GABA)
Short description : Class of drugs
A GABA analogue is a compound which is an analogue or derivative of the neurotransmitter gamma-Aminobutyric acid (GABA) (the IUPAC of which is 4-aminobutanoic acid).
Many GABA analogues are used as drugs, especially as anticonvulsants , sedatives , and anxiolytics .
List of GABA analogues
