Interactions between your drugs
berotralstat oteseconazole
Applies to: berotralstat and oteseconazole
ADJUST DOSE: Coadministration with inhibitors of P-glycoprotein (P-gp) and/or breast cancer resistance protein (BCRP) may significantly increase the plasma concentrations of berotralstat. Berotralstat is a substrate of both P-gp and BCRP. Coadministration with potent P-gp and BCRP inhibitor cyclosporine increased berotralstat peak plasma concentration (Cmax) and total systemic drug exposure (AUC 0-inf) by 25% and 69%, respectively. Increased plasma concentrations of berotralstat may increase the risk of adverse effects, including the potential for QT prolongation. Berotralstat may cause concentration-dependent prolongation of the Fridericia-corrected QT interval (QTcF). A mean increase in the QTcF interval of 15.9 milliseconds has been reported at 3-times the recommended dose of berotralstat; however, berotralstat has not been shown to prolong the QT interval to any clinically relevant extent when administered at the recommended daily dose of 150 mg. Data are not available for other, less potent P-gp and/or BCRP inhibitors.
MANAGEMENT: The dosage of berotralstat should be reduced to 110 mg once daily in patients requiring chronic coadministration with P-gp and/or BCRP inhibitors. Patients should be advised to contact their physician if they experience undue adverse effects of berotralstat such as abdominal pain, vomiting, or diarrhea. Patients should seek prompt medical attention if they experience symptoms that could indicate the occurrence of torsade de pointes such as dizziness, lightheadedness, fainting, palpitations, irregular heartbeat, shortness of breath, or syncope.

Drug and food interactions
oteseconazole food
Applies to: oteseconazole
ADJUST DOSING INTERVAL: Food enhances the oral bioavailability of oteseconazole. When administered with a high-fat, high-calorie meal (800 to 1000 calories; 50% fat), oteseconazole peak plasma concentration (Cmax) and systemic exposure (AUC 0-72h) increased by 45% and 36%, respectively. However, no significant differences were observed with a low-fat, low-calorie meal.
MANAGEMENT: Oteseconazole should be administered with food.
