This randomized, open-label, crossover study investigated the influence of food on the pharmacokinetics of extended-release hydromorphone in 30 healthy volunteers. Participants received extended-release hydromorphone 16 mg in the fasted state and immediately after a high-fat breakfast. In addition, the pharmacokinetics of a 16-mg dose of extended-release hydromorphone and a 16-mg daily dose (4 mg qid) of immediate-release hydromorphone in the fasted state were compared. Treatments were separated by washout periods of 7 to 14 days. Naltrexone was given throughout each treatment period to block the opioid effects of hydromorphone. The 90% confidence intervals (CIs) of the ratios of geometric means for maximum plasma concentrations (C(max)) and area under the plasma concentration-time curve (AUC) for extended-release hydromorphone in the fed and fasted states were within the bioequivalence criteria range of 80% to 125%. In the fasted state, the 90% CIs of the ratios of AUC geometric means for extended-release hydromorphone and immediate-release hydromorphone were also within the bioequivalence range. Both hydromorphone treatments were well tolerated. This study shows that the bioavailability of extended-release hydromorphone is not affected by food and that the bioavailability of extended-release hydromorphone under fasting conditions is comparable with that of the immediate-release formulation when administered at the same total daily dose.
