Description

ketoconazole), and protease inhibitors (e.g., ritonavir), can increase the plasma concentration of oxycodone, resulting in increased or prolonged opioid effects. After stopping a CYP3A4 inhibitor, as the effects of the inhibitor decline, the oxycodone plasma concentration will decrease [see CLINICAL PHARMACOLOGY ] , resulting in decreased opioid efficacy or a withdrawal syndrome in patients who had developed physical dependence to ENDOCET. Inducers of CYP3A4 The concomitant use of ENDOCET and CYP3A4 inducers, such as rifampin, carbamazepine, and phenytoin, can decrease the plasma concentration of oxycodone [see CLINICAL PHARMACOLOGY ] , resulting in decreased efficacy or onset of a withdrawal syndrome in patients who have developed physical dependence to ENDOCET [see WARNINGS ] .
