omnaris and Troleandomycin Interactions

Interactions between omnaris(ciclesonide nasal) and Troleandomycin (troleandomycin)

troleandomycin and ciclesonide nasal (Moderate Drug-Drug)

MONITOR: Coadministration of inhaled ciclesonide with potent inhibitors of CYP450 3A4 may increase systemic bioavailability of the pharmacologically active metabolite, des-ciclesonide, which is a substrate of the isoenzyme. In one study, administration of orally inhaled ciclesonide in combination with the potent inhibitor ketoconazole resulted in an approximately 3.6-fold increase in steady-state des-ciclesonide systemic exposure (AUC), while levels of ciclesonide remained unchanged. In another study, coadministration of orally inhaled ciclesonide with erythromycin, a less potent inhibitor, had no effect on the pharmacokinetics of des-ciclesonide.

MANAGEMENT: Caution is advised if ciclesonide is prescribed with potent CYP450 3A4 inhibitors such as itraconazole, ketoconazole, voriconazole, nefazodone, delavirdine, protease inhibitors, and ketolide and certain macrolide antibiotics. Patients should be monitored for systemic glucocorticoid effects including symptoms of hypercorticism (e.g., acne, easy bruising, moon face, edema, hirsutism, buffalo hump, skin striae, irregular menstruations), adrenal suppression (which reduces patient's ability to respond to stress situations), immunosuppression, osteoporosis, glucose intolerance, and exacerbation of diabetes mellitus.
