摘要: Objective. The objectives of the study were to determine absolute bioavailability fentanyl from buccal soluble film, estimate percentage a dose absorbed through mucosa, and compare equivalent doses administered either as single or multiple units. Design. Open-label, randomized, four-period, Latin-square crossover pharmacokinetic study. Setting. Inpatient phase 1 unit. Patients. Twelve healthy volunteers. Interventions. Injectable citrate (200 µg) by intravenous infusion, injectable (800 µg/16 mL) orally, film (800 µg) four separate 200 µg films simultaneously. Outcome Measures. Plasma concentrations after dosing; parameters. Results. two treatments bioequivalent both had an 71%. mucosa was calculated be 51%. Conclusions. Fentanyl effectively delivers high nearly identical plasma profiles are obtained when delivered dosage units.
