PCE Dispertab and Ramelteon Tablets

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 and effects of ramelteon. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if you experience excessive drowsiness or increased side effects. 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: Coadministration with potent inhibitors of CYP450 3A4 and/or 2C9 may increase the plasma concentrations and pharmacologic effects of ramelteon, which is partially metabolized by these isoenzymes. In healthy volunteers, administration of a single 16 mg oral dose of ramelteon following pretreatment with the potent CYP450 3A4 inhibitor ketoconazole (200 mg orally twice daily for 4 days) increased ramelteon peak plasma concentration (Cmax) by 36% and systemic exposure (AUC) by 84% compared to administration of ramelteon alone. Likewise, coadministration with fluconazole, a potent CYP450 2C9 inhibitor, resulted in an increase of approximately 150% in the Cmax and AUC of ramelteon following a single 16 mg oral dose. Similar pharmacokinetic changes were also observed with its biologically active metabolite, known as M-II.

MANAGEMENT: Caution is advised if ramelteon is prescribed in combination with potent inhibitors of CYP450 3A4 (e.g., itraconazole, ketoconazole, posaconazole, voriconazole, conivaptan, delavirdine, nefazodone, protease inhibitors, ketolide and certain macrolide antibiotics) and/or CYP450 2C9 (e.g., fluconazole, gemfibrozil, imatinib, miconazole). A reduction in the ramelteon dosage may be necessary in patients who experience excessive sedation.
