This is a fixed-dose combination NSAID analgesic, pairing aceclofenac (a non-steroidal anti-inflammatory drug) with paracetamol/acetaminophen (an analgesic-antipyretic). It is commonly marketed for pain, inflammation, and fever relief. Typical clinical uses include:
Osteoarthritis - joint pain and stiffness relief
Rheumatoid arthritis - pain and inflammation control
Dysmenorrhea (menstrual cramps) - sometimes used off-label
How it works
Aceclofenac inhibits cyclooxygenase (COX-1/COX-2), reducing prostaglandin synthesis, which lowers inflammation and pain at the site of tissue injury. NSAIDs of this class (aceclofenac, diclofenac, etc.) work through this same mechanism - Maudsley Prescribing Guidelines in Psychiatry, 15ed.
Paracetamol acts more centrally, modulating pain signaling and the hypothalamic thermoregulatory center to reduce fever, with a comparatively weak peripheral anti-inflammatory effect.
Together, the combination gives more effective pain and fever control than either drug alone at standard doses, while allowing a somewhat lower NSAID dose to be used.
Important precautions
Take after food to reduce gastrointestinal irritation/risk of ulcers.
Avoid in active peptic ulcer disease, severe hepatic or renal impairment, and third-trimester pregnancy.
Use caution with alcohol (raises risk of GI bleeding and hepatotoxicity), and avoid exceeding the recommended paracetamol dose (hepatotoxicity risk).
Not recommended for long-term self-use without medical supervision; caution in patients with cardiovascular disease, asthma/NSAID-sensitivity, or those on anticoagulants.
Always follow the dose and duration prescribed by a physician or as printed on the label - this combination is typically available only via prescription in many markets, though OTC in some.
