On physical examination, the patient is confused, agitated, and sweating profusely, particularly from his palms. Generalized pallor is present. What is the mechanism of action of the drug recommended to treat this patients most likely condition?? A: It increases the duration of GABA-gated chloride channel opening., B: It increases the frequency of GABA-gated chloride channel opening., C: It decreases the frequency of GABA-gated chloride channel opening., D: It activates the GABA receptors by binding at the GABA binding site., E: It decreases the duration of GABA-gated chloride channel opening.,  <response>: This is a clinical vignette describing a patient with a history of chronic alcoholism who is brought to the ER unconscious and treated for acute alcohol intoxication. The next day, he is confused, agitated, sweating profusely, and has generalized pallor, suggesting alcohol withdrawal syndrome. The question asks about the mechanism of action of the drug recommended to treat this condition. Based on the clinical presentation, the patient is likely experiencing alcohol withdrawal, which causes CNS hyperexcitability. The drug of choice is benzodiazepines like diazepam, which enhance the effect of the inhibitory neurotransmitter GABA and reduce CNS hyperexcitability. B: It increases the frequency of GABA-gated chloride channel opening.
