We compared the pharmacokinetics of 10 mg oral oxycodone in four groups of 10 patients each, aged 20-40, 60-70, 70-80, and 80-90 years. Patients aged 70-80 and 80-90 years had 50-80% higher mean exposure to oxycodone (P < 0.05) and a twofold higher plasma oxycodone concentration (P < 0.05) than the young adults 12 h after ingestion of the drug. Because oxycodone pharmacokinetics depend to a great extent on the age of the subject, it is important to titrate the analgesic dose individually, particularly in the elderly.
