GABA-A receptors appear to have at least three allosteric sites at which modulators act: a site at which benzodiazepines act by increasing the opening frequency of gamma-aminobutyric acid-activated chloride channels a site at which barbiturates act to prolong the duration of channel opening and a site at which some steroids may act. 7, 8 This might be the probable reason that there was a significant improvement in the signs and symptoms of the patients. Although the anxiolytic and sedative effects are mainly attributed to the modulation of GABA-ergic transmission, the mechanism of action has not been fully investigated in humans. 12 It inhibits enzyme-induced breakdown of GABA in the brain resulting in sedation.
