Quizplus · Accepted Answer

Xanax and Valium are benzodiazepines which act as positive allosteric modulators of GABA-A receptors in the brain. GABA (Gamma-Aminobutyric acid) is a neurotransmitter that inhibits the activity of the central nervous system and is responsible for reducing anxiety. By enhancing the effects of GABA, these tranquilizers decrease the activity of neurons in the brain, leading to a sedative and anxiolytic effect.
