mechanism of action of anxiolytics
... A majority of the synapses in the mammalian CNS use the amino acids l-glutamic acid, glycine, or ␥-aminobutyric acid (GABA) for signaling. GABA is formed by the decarboxylation of l-glutamate, stored in neurons, and released, and its action is terminated by reuptake; GABA’s action mimics the natural ...
