Drug interactions: Because rifampin induces a number of phase I cytochrome P450 enzymes and phase II enzymes (see Chapter 1), it canThis may necessitate higher dosages for coadministered drugs, a switch to drugs less affected by rifampin, or replacement of rifampin with rifabutin. Major drugdrug interactions can occur especially between the rifamycins and pro-tease inhibitors and non-nucleoside reverse transcriptase inhibitors (NNRTI).Rifamycins [rifampicin (rifampin), rifabutin and rifapentine] are metabolized by hepatic microsomal cytochrome P450 and induce their Drug-Drug Interactions.
