Istradefylline and Lefamulin
Determining the interaction of Istradefylline and Lefamulin and the possibility of their joint administration.
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.
Consumer:Consumer information for this interaction is not currently available.MONITOR: Coadministration with inhibitors of CYP450 3A4 and/or P-gp may increase the plasma concentrations of lefamulin, which is a substrate of both the isoenzyme and efflux transporter. When oral lefamulin was administered with oral ketoconazole, a potent CYP450 3A4/P-gp inhibitor, mean lefamulin peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 58% and 165%, respectively. Coadministration of intravenous lefamulin with oral ketoconazole increased mean lefamulin Cmax and AUC by 6% and 31%, respectively. Increased exposure to lefamulin may increase the risk of QT interval prolongation, which has been associated with ventricular arrhythmias including torsade de pointes and sudden death. MANAGEMENT: Caution is advised when lefamulin is used with CYP450 3A4 and/or P-gp inhibitors. Patients should be monitored for increased adverse effects and seek prompt medical attention if they experience symptoms that could indicate the occurrence of torsade de pointes such as dizziness, lightheadedness, fainting, palpitation, irregular heart rhythm, shortness of breath, or syncope.
