Stiripentol is an anticonvulsant drug used in the treatment of epilepsy. It recently proved to increase the GABAergic transmission in vitro in an experimental model of immature rat. Clinical studies were based on the fact that STP also acts as an inhibitor of CYP3A4, CYP1A2, and CYP2C19 in vivo in epileptic patients. Side effects are largely due to the increase in plasma concentrations of other anticonvulsants and can be reduced by lowering the dose of those drugs. Nausea and vomiting are particularly noted when used in combination with sodium valproate. It appears to increase the potency of phenobarbital, primidone, phenytoin, carbamazepine, clobazam and diazepam.
