title: Bioavailability of medication after laparoscopic cholecystectomy.
abstract: Bioavailability of medication after laparoscopic cholecystectomy has not been studied previously. There is concern about the ability of patients to tolerate oral medication postoperatively and the optimal timing of hospital discharge. In this study, each subject received 20 mg/kg acetaminophen (po) preoperatively, with a repeat dose at 6 (group 1), 12 (group 2), or 24 h (group 3) postoperatively. Serum levels were obtained 40 and 90 min after each ingestion. Bioavailability of medication was significantly decreased (p < 0.01) 6 h (group 1) and 12 h (group 2) postoperatively. Bioavailability returned to baseline by 24 h after laparoscopic cholecystectomy (group 3). This study indicates that oral medication should be used judiciously during the first 12 h after laparoscopic surgery.
