摘要

This study investigated whether the pharmacokinetics of sublingual fentanyl (SLF), a fentanyl citrate formulation for breakthrough pain (BTP) in opioid-tolerant cancer patients, are influenced by ethnicity. Twenty-one healthy Japanese and Caucasian volunteers (20-45 years) were to receive single doses of SLF (50, 100, 150 and 200 mug) at >=3-day intervals. Area under the plasma concentration-time curve and maximum plasma concentration (C_max) increased with ascending dose, and were statistically similar between ethnic groups (p=0.6274 and p=0.8943, respectively). Time to first observed plasma fentanyl concentration was 10-15 min and time to C_max was 30-45 min, for all doses. SLF was well tolerated, irrespective of ethnicity. The findings suggest that SLF should be an effective analgesic for cancer BTP in Japanese and Caucasian patients.
