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).
