Drug and food/lifestyle interactions
ribavirin food/lifestyle
Applies to: Ribasphere (ribavirin)
ADJUST DOSING INTERVAL: Food enhances the oral absorption and bioavailability of ribavirin. Administration of a single oral dose of ribavirin following a high-fat meal delayed absorption (Tmax was doubled) but increased the mean peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) by up to 70% compared to administration in the fasting state.
MANAGEMENT: To ensure maximal oral absorption, ribavirin should be administered with or immediately after a meal.
