- Scemblix (asciminib)
Interactions between your drugs
cannabidiol asciminib
Applies to: cannabidiol and Scemblix (asciminib)
Cannabidiol is a substrate for CYP450 3A4 and CYP450 2C19. Cannabidiol is metabolized in the liver and the gut (primarily in the liver) by CYP450 2C19 and CYP450 3A4 enzymes, and UGT1A7, UGT1A9, and UGT2B7 isoforms. Coadministration of cannabidiol with itraconazole (a potent inhibitor of CYP450 3A4) increased cannabidiol exposure by less than 10%; exposure to fluconazole (a potent CYP450 2C19 inhibitor) was increased to less than 20%. Both values are not considered clinically meaningful.

Drug and food interactions
cannabidiol food
Applies to: cannabidiol
ADJUST DOSING INTERVAL: Food may affect the plasma concentrations of cannabidiol. In healthy volunteers, administration of cannabidiol with a high-fat/high-calorie meal increased cannabidiol peak plasma concentration (Cmax) by 5-fold and systemic exposure (AUC) by 4-fold and reduced the total variability compared with administration in the fasted state.
GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of cannabidiol. The proposed mechanism is inhibition of CYP450 3A4-mediated metabolism of cannabidiol by certain compounds present in grapefruit. The interaction has not been studied, but the product labeling for cannabidiol recommends consideration of a dosage reduction when used with strong or moderate inhibitors of CYP450 3A4. 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.
MANAGEMENT: Cannabidiol should be taken about the same time each day consistently either with or without food. Patients should limit the consumption of grapefruit and grapefruit juice. If they are coadministered, cannabidiol levels should be monitored and the dosage adjusted as necessary.

asciminib food
Applies to: Scemblix (asciminib)
ADJUST DOSING INTERVAL: Food may reduce the oral bioavailability of asciminib. When a single 40 mg dose of asciminib was administered with a low-fat meal (400 calories; 25% fat) in healthy volunteers, asciminib peak plasma concentration (Cmax) and systemic exposure (AUC) decreased by 35% and 30%, respectively, compared to asciminib administered in the fasted state. Administration with a high-fat meal (1000 calories; 50% fat) decreased the Cmax and AUC of asciminib by 68% and 62%, respectively.
MANAGEMENT: To ensure adequate asciminib exposures, food consumption should be avoided for at least 2 hours before and 1 hour after taking asciminib.
