phenobarbital will decrease the level or result of stiripentol by affecting hepatic enzyme CYP1A2 metabolism. Stay clear of or Use Alternate Drug. If unable to prevent coadministration of stiripentol with potent CYP1A2 inducers, increase stiripentol dose.
Barbiturates are metabolized mostly by the hepatic microsomal enzyme process, as well as metabolic products are excreted while in the urine and, fewer usually, from the feces. Close to twenty five% to 50% of the dose of phenobarbital is removed unchanged inside the urine.

Just like secobarbital sodium and pentobarbital sodium, other barbiturates (together with amobarbital) is likely to be anticipated to lose their effectiveness for inducing and preserving rest soon after about check here 2 weeks.
Withdrawal indicators as a result of Actual physical dependence adhering to Long-term use of large doses of barbiturates may perhaps include things like delirium, convulsions, and Dying.
