Cyp inhibitors or inducers
WebJun 30, 2015 · Protease inhibitors (PIs) are metabolized in the liver by CYP3A isoenzymes; therefore, their metabolism may be altered by CYP inducers or inhibitors. Coadministration of PIs with ritonavir (RTV), a potent CYP3A inhibitor, is used to intentionally increase PI systemic exposure (ie, pharmacokinetic enhancing, or ”boosting”). WebInhibitors of CYP3A4 can be classified by their potency, such as: Strong inhibitor being one that causes at least a 5-fold increase in the plasma AUC values, or more than 80% …
