Oxycodone ER and PCE Dispertab

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Erythromycin may increase the blood levels of oxycodone. This may increase side effects such as drowsiness, dizziness, lightheadedness, difficulty concentrating, and impairment in thinking and judgment. In severe cases, low blood pressure, respiratory distress, fainting, coma, or even death may occur. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. You should seek medical attention if you experience dizziness, fainting, confusion, excessive drowsiness, slow heart rate, and/or shallow or difficult breathing. Do not drink alcohol during treatment with oxyCODONE, and do not use more than the dose prescribed by your doctor. Also, avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how these medications affect you, and use caution when getting up from a sitting or lying position. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

MONITOR CLOSELY: Coadministration with inhibitors of CYP450 3A4 may increase the plasma concentrations of oxycodone, which is substantially metabolized by the isoenzyme. Increased oxycodone concentrations could conceivably increase or prolong adverse drug effects and may cause potentially fatal respiratory depression. According to some manufacturers, oxycodone systemic exposure (AUC) was, on average, approximately 2.4-times higher (range 1.5 to 3.4) during coadministration with itraconazole (200 mg orally for 5 days); 1.8 times higher (range 1.3 to 2.3) during coadministration with telithromycin (800 mg orally for 4 days); 3.6 times higher (range 2.7 to 5.6) during coadministration with voriconazole (200 mg twice daily for 4 days); and 1.7 times higher (range 1.1 - 2.1) during coadministration with grapefruit juice (200 mL three times daily for 5 days). Because oxycodone is also partially metabolized by CYP450 2D6, the magnitude of interaction may be even greater with concomitant use of a CYP450 3A4 and a CYP450 2D6 inhibitor, or concomitant use of a drug that is a dual inhibitor of both isoenzymes.

MANAGEMENT: Extreme caution is advised if oxycodone is prescribed with CYP450 3A4 inhibitors, particularly potent and moderate inhibitors (e.g., azole antifungal agents, protease inhibitors, aprepitant, ciprofloxacin, chloramphenicol, clarithromycin, cobicistat, conivaptan, crizotinib, delavirdine, diltiazem, dronedarone, erythromycin, fusidic acid, idelalisib, imatinib, mibefradil, mifepristone, nefazodone, netupitant, quinupristin-dalfopristin, telithromycin, verapamil) or weak inhibitors that also inhibit CYP450 2D6 (e.g., abiraterone, amiodarone, cimetidine, pazopanib, ranolazine). Some authorities advise that the oxycodone dose may need to be adjusted. A fatal overdose may occur following the initiation of a CYP450 3A4 inhibitor in patients already receiving oxycodone. Patients should be closely monitored for signs and symptoms of sedation, respiratory depression, and hypotension. Following discontinuation of the CYP450 3A4 inhibitor, patients should be monitored for reduced efficacy of oxycodone or development of withdrawal symptoms due to reduced plasma oxycodone levels.
