Rifampin induction
WebRifampin is a potent inducer of CYP3A4 in vitro and precipitates numerous drug-drug interactions (DDIs) when coadministered with CYP3A4 substrates. In the current study, we have critically assessed reported rifampin in vitro CYP3A4 induction data in Fa2N-4, HepaRG, and cryopreserved or primary human … Webdrugs that cause clinically relevant CYP3A4 induction have been reported, including the antibiotic rifampin and the anticonvulsants phenobarbitone, phenytoin, and carbamazepine (review article by McInnes and Brodie, 1988). Rifampin causes auto-induction because CYP3A4, which it induces, is also responsible for its clearance (Acocella, 1978).

WebRifabutin reduces serum concentrations of an- tiretroviral agents, but less so than rifampin. To avoid a reduced therapeutic response, therapeutic failure, or toxic reactions when rifampin is added to or discontinued from medication regimens, cli- nicians need to be cognizant of these interactions. WebSep 24, 2013 · Rifampicin is frequently used as a positive control or calibrator for evaluating the CYP3A4 induction potential of test compounds. Therefore, a large amount of in vitro rifampicin data is available in the literature. In general, cultures of primary human hepatocytes are believed to be the best in vitro model for simulating in vivo conditions.
