Rifampicin - Wikipedia

WebIn addition, rifampicin induces some drug transporter proteins, such as intestinal and hepatic P-glycoprotein. Full induction of drug-metabolising enzymes is reached in about 1 … Rifampicin is the most powerful known inducer of the hepatic cytochrome P450 enzyme system, including isoenzymes CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP3A4, CYP3A5, and CYP3A7. It increases metabolism of many drugs and as a consequence, can make them less effective, or even ineffective, by decreasing their levels. For instance, patients undergoing long-term anticoagulation therapy with warfarin have to increase their dosage of warfarin and have their clo… WebRifampin also induces Phase II metabolizing enzymes, which are responsible for biotransformations such as glucuronidation and sulfation, as well as the efflux pump p-glycoprotein and other drug transporters. Induction of these enzymes can lead to reduced plasma concentrations of co-administered drugs that are substrates of these enzymes. sharif museum taif
