Abstract The combination of two analgesic agents offers several advantages in the treatment of chronic pain. Paracetamol (acetaminophen) has central analgesic activity without a nonsteroidal anti-inflammatory drug (NSAID)-like or opioid-like effect. Oxycodone is a semisynthetic opioid agonist. The oral fixed-dose combination of oxycodone and paracetamol immediate-release formulation has a synergistic mechanism of action that is useful for moderate-to-severe pain and for nonresponders to NSAIDs or paracetamol alone. This fixed-dose combination offers several advantages: lower individual drug doses can be used because of their synergistic mechanisms of action, its opioid-sparing effect and it has a good efficacy and tolerability profile. Efficacy and safety of this fixed-dose combination were assessed in a wide range of clinical settings: in patients with osteoarthritis or chronic musculoskeletal pain, including when complicated by a neuropathic component; for chronic pain in elderly patients; cancer-related pain; postoperative pain; and for neuropathic pain, in the latter case usually given in combination with an NSAID or other drugs. The large variety of indications for which this fixed-dose combination may be useful can be attributed to the pharmacological synergy between oxycodone and paracetamol and because lower individual drug dosages can be used, suggesting that this should be a first-line agent for the treatment of chronic moderate-to-severe pain.
