WebApr 13, 2024 · GABA A receptors are inhibitory chloride channels located in the mammalian central nervous system. They are targeted by many heavily used pharmaceuticals such as benzodiazepine-based sedatives, hypnotics, anxiolytics, barbiturate-based anticonvulsants, and general anesthetics of a broad range of … WebMay 16, 2024 · Benzodiazepines are used to treat anxiety, seizures, to induce anesthesia, and insomnia. They work by enhancing the binding of the neurotransmitter GABA to the GABA A receptor. Once bound, it causes a “depressive” effect on neuronal synaptic transmission that lead to reduced anxiety, sleepiness, sedation, and an anticonvulsive …
