Painkiller, Anti-inflammatory, Muscle Relaxant (combination)
Last reviewed July 2026
Who is this for?
This is a combination tablet containing three medicines: Aceclofenac (a painkiller that reduces swelling), Paracetamol (which brings down pain and fever), and Chlorzoxazone (a muscle relaxant that eases stiff or tight muscles). Together, they work to relieve pain, inflammation, and muscle spasms.
Inhibits COX-1 and COX-2 enzymes (aceclofenac and paracetamol) to reduce prostaglandin synthesis, decreasing pain and inflammation, while chlorzoxazone acts as a central nervous system depressant to relax skeletal muscles and reduce muscle spasms.
