Enzyme inducing medication
WebEnzyme induction refers to an increase in the rate of hepatic metabolism, mediated by increased transcription of mRNA encoding the genes for drug-metabolizing enzymes. This leads to a decrease in the concentrations of drugs metabolized by the same enzyme. Rifampicin is a potent inducer of CYP3A4 and can result in clinically significant … WebCYP3A4 Induction: Drugs that induce liver enzymes increase the metabolism and clearance of zonisamide and decrease its half-life. The half-life of zonisamide following a 400 mg dose in patients concurrently on enzyme-inducing AEDs such as phenytoin, carbamazepine, or phenobarbital was between 27-38 hours, the half-life of
