Aceclofenac 100mg. + Paracetamol 325mg. + Thiocolchicoside 4mg. is a combination formulation commonly used to treat pain, inflammation, and muscle spasms. Aceclofenac is a non-steroidal anti-inflammatory drug (NSAID) that helps reduce inflammation, pain, and swelling by inhibiting COX enzymes. Paracetamol (acetaminophen) provides additional pain relief and reduces fever. Thiocolchicoside is a muscle relaxant that works by reducing muscle spasms and providing relief from associated discomfort. This combination is typically used for conditions like musculoskeletal pain, back pain, sprains, and strains, offering a synergistic effect by targeting pain, inflammation, and muscle spasms simultaneously.
