Drug Mode of Action ::  

Zolpidem is an imidazopyridine derivative that acts by binding to the benzodiazepine (BZD) receptors of the GABA receptor complex resulting in neuronal hyperpolarisation, action potential inhibition, increased in chloride conductance and decreased in neuronal excitability. It has strong sedative action but only minimal anxiolytic, myorelaxant and anticonvulsant properties due to its selectivity for the BZ1-receptor over the BZ2-receptor. Zolpidem has a rapid onset but short duration of hypnotic action.

Drug Interactions ::

Flumazenil reverses the sedative/hypnotic effect of zolpidem. Increased depressant effects w/ CNS depressants (e.g. sedatives, antihistamines, alcohol). Additive effect on decreased alertness and psychomotor performance w/ imipramine and chlorpromazine. Increased plasma concentration w/ itraconazole, ketoconazole and other CYP3A4 inhibitors. May decrease plasma concentration w/ CYP3A4 inducers (e.g. carbamazepine). Reduced hypnotic effect w/ rifampicin. Potentially Fatal: Increased risk of prolonged sedation and respiratory depression w/ ritonavir.
