MONITOR: Bowel cleansing as well as overuse of certain laxatives may cause electrolyte loss and increase the risk of torsade de pointes ventricular arrhythmia in patients treated with drugs that prolong the QT interval. Electrolyte disturbances including hypokalemia and hypomagnesemia have been reported with laxative abuse and are known risk factors for torsade de pointes associated with QT interval prolongation.
MANAGEMENT: Patients treated with drugs that prolong the QT interval should exercise caution when self-medicating with laxatives. The recommended dosage and duration of use should not be exceeded. Patients treated with lactulose for more than six months should be monitored periodically for electrolyte imbalance. Patients should be advised to 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.

ADJUST DOSING INTERVAL: In pharmacokinetic studies, revumenib was administered while fasting or with a low fat meal. Revumenib has not been studied with meals of higher fat content and the impact on its pharmacokinetic parameters is unknown.
MONITOR: Grapefruit, grapefruit juice, grapefruit hybrids, pomelos, star-fruit, and Seville oranges may increase the plasma concentrations of revumenib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. The extent and clinical significance are unknown. In pharmacokinetic studies in patients with relapsed or refractory acute leukemia, revumenib area under the concentration-time curve (AUC) and peak plasma concentration (Cmax) increased 2-fold following concomitant use with the potent CYP450 3A4 inhibitors posaconazole, itraconazole, and voriconazole, and 2.5-fold following concomitant use with the potent CYP450 3A4 inhibitor cobicistat. However, clinically significant differences in revumenib pharmacokinetics were not observed when used concomitantly with the moderate CYP450 3A4 inhibitors fluconazole and isavuconazole. In general the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Moreover, pharmacokinetic alterations associated with interactions involving grapefruit juice are often subject to a high degree of interpatient variability. Increased exposure to revumenib may increase the risk of QT interval prolongation, which has been associated with ventricular arrhythmias including torsade de pointes and sudden death.
MANAGEMENT: Due to the potential impact of high fat content meals on revumenib absorption and exposure, it is recommended that revumenib be administered while fasting or with a low fat meal (approximately 400-500 calories, with 25% of calories from fat). In addition, if grapefruit, grapefruit juice, grapefruit hybrids, pomelos, star-fruit, or Seville oranges are consumed during treatment with revumenib, assess patient tolerability and monitor for serious adverse effects (e.g., QT prolongation and torsade de pointes arrhythmia, differentiation syndrome, neutropenia, thrombocytopenia).
