Synonyms:
Quest test code 18885, Oxycodone Sr
Clinical significance:
For therapeutic drug monitoring of oxycodone (Oxycontin®, Percocet®, Percodan®). Oxycodone is a semisynthetic opioid analgesic. Steady state concentration is reached in 24-36 hours after initiation of therapy. Elimination half-life of oxycodone is 4.5 hours for controlled release and 3.2 hours for immediate release formulations. Peak plasma concentration of oxycodone is 11, 21, 39, 99, or 156 ng/mL after a single oral dose of 10, 20, 40, 80, or 160 mg respectively. Oxymorphone is a minor but active metabolite of oxycodone that is present at lower concentration in the circulation. Therapeutic concentrations for oxymorphone have not been established.
