Drug Interaction Report

CONTRAINDICATED: The central nervous system and respiratory depressant effects of sodium oxybate, which is the sodium salt of gamma hydroxybutyrate (GHB), may be potentiated by concomitant use of sedative-hypnotic agents. An increased risk of serious adverse reactions such as respiratory depression, hypotension, profound sedation, syncope, coma, and even death should be anticipated.

MANAGEMENT: The use of sodium oxybate in combination with sedative-hypnotic agents is considered contraindicated.

CONTRAINDICATED: Alcohol may potentiate the central nervous system and respiratory depressant effects of sodium oxybate, which is the sodium salt of gamma hydroxybutyrate (GHB). An increased risk of serious adverse reactions such as respiratory depression, hypotension, profound sedation, syncope, coma, and even death should be anticipated.

ADJUST DOSING INTERVAL: Food may delay the absorption and significantly decrease the bioavailability of sodium oxybate. When sodium oxybate was administered immediately after a high-fat meal, the time to reach peak plasma concentration (Tmax) increased from 0.75 hour to 2 hours, the peak plasma concentration (Cmax) decreased by a mean of 59%, and the systemic exposure (AUC) decreased by a mean of 37%.

MANAGEMENT: The concomitant use of sodium oxybate with alcohol is considered contraindicated. The first dose of sodium oxybate should be taken at least 2 hours after a meal to ensure maximal absorption.
