WebInduction Ryuta Asaumi1, Karsten Menzel2, Wooin Lee3, Ken-ichi Nunoya1, Haruo Imawaka1, Hiroyuki Kusuhara4 and Yuichi Sugiyama5,* As rifampicin can cause the induction and inhibition of multiple metabolizing enzymes and transporters, it has been chal-lenging to accurately predict the complex drug–drug interactions (DDIs). WebSep 24, 2013 · Feasibility of this hybrid model was investigated using rifampicin, a well-characterized and potent inducer of CYP3A4. 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.
