Drug and food interactions
venetoclax food
Applies to: Venclexta (venetoclax)
ADJUST DOSING INTERVAL: Food enhances the oral bioavailability of venetoclax. Relative to fasting conditions, venetoclax systemic exposure (AUC) increased by approximately 3.4-fold when administered with a low-fat meal and by 5.1- to 5.3-fold when administered with a high-fat meal.
GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of venetoclax. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. 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. Increased venetoclax exposure may potentiate the risk of tumor lysis syndrome, particularly at initiation of therapy and during the dosage ramp-up phase, as well as other adverse effects such as diarrhea, nausea, vomiting, neutropenia, anemia, and thrombocytopenia.
MANAGEMENT: Venetoclax should be administered with a meal and water at approximately the same time each day. Patients should avoid consumption of grapefruit products, Seville oranges, and starfruit during treatment with venetoclax.

tamsulosin food
Applies to: tamsulosin
ADJUST DOSING INTERVAL: Food may delay the gastrointestinal absorption of tamsulosin. The time to maximum plasma concentration (Tmax) is reached by 4 to 5 hours under fasted conditions and by 6 to 7 hours when tamsulosin is administered with food. The delay in Tmax has the desirable effect of smoothing the tamsulosin plasma concentration profile, thereby reducing fluctuation of the plasma peak and trough concentrations with multiple dosing. Food may also affect the extent of absorption of tamsulosin. It has been reported that taking tamsulosin under fasted conditions results in a 30% increase in bioavailability (AUC) and 40% to 70% increase in peak plasma concentration (Cmax) compared to fed conditions. The effects of food on the pharmacokinetics of tamsulosin are consistent regardless of whether tamsulosin is taken with a light meal or a high-fat meal.
MANAGEMENT: To ensure uniformity of absorption, tamsulosin should be administered approximately one-half hour following the same meal each day.
