Drug and food interactions

Moderate

sodium phenylbutyrate food

Applies to: Buphenyl (sodium phenylbutyrate)

ADJUST DOSING INTERVAL: Coadministration with a high-fat meal may reduce the rate and extent of absorption of sodium phenylbutyrate. When a single 3 g-1 g dose of sodium phenylbutyrate-taurursodiol (sodium phenylbutyrate-ursodoxicoltaurine) was administered to healthy volunteers in the presence of a high-fat, high-calorie meal (approximately 800 to 1000 calories; 500 to 600 calories from fat, 250 calories from carbohydrate, 150 calories from protein), sodium phenylbutyrate peak plasma concentration (Cmax) decreased by 75% and systemic exposure (AUC) decreased by 55%. The Cmax for taurursodiol was not significantly affected, but AUC was increased by 46%. The clinical significance of these changes has not been established. In premarketing studies, patients were advised to take the drug before a meal.

MANAGEMENT: The prescribing information recommends administration of sodium phenylbutyrate-taurursodiol before a meal or snack, particularly in patients of low body weight (less than 70 kg).

Therapeutic duplication warnings

Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition. This can be intentional in cases where drugs with similar actions are used together for demonstrated therapeutic benefit. It can also be unintentional in cases where a patient has been treated by more than one doctor, or had prescriptions filled at more than one pharmacy, and can have potentially adverse consequences.
