Oxycodone and naloxone (ATC N02AA55) is a fixed-dose combination opioid analgesic used for the management of severe pain, particularly in patients requiring long-term opioid therapy where opioid-induced constipation is a concern. Oxycodone acts primarily as a μ-opioid receptor agonist, while naloxone is a competitive opioid antagonist included to counteract opioid-induced constipation by local action in the gut. The oral combination is approved and used widely in clinical practice.
Pharmacokinetic parameters following repeated oral administration in healthy adults; mean values are primarily from published population PK studies of oxycodone/naloxone prolonged-release tablets.
