“ABSTRACT Background: Alprazolam is a commonly used benzodiazepine in clinical practice, and when coingested with ethanol, alprazolam can increase behavioral irritability and aggression.”
“Conclusions: Ethanol might increase the toxicity of alprazolam by inhibiting the activity of CYP3A4, although other pharmacokinetic processes may be affected.”
“ Ethanol could change the conformation of CYP3A4 and affect alprazolam binding.”
“In silico molecular docking was applied to analyze the change in the CYP3A4–alprazolam-binding conformation when ethanol was coadministered with alprazolam.”
“Results: Compared with alprazolam administered alone (2 mg/kg), the Cmax of alprazolam increased when ethanol was simultaneously administered at 3 g/kg.”
“The concentrations of alprazolam significantly increased by 39%, 17%, 105%, and 642% at 5, 10, 30, and 120 min intervals in the brain when coadministered with ethanol , respectively.”
