Aceclofenac+paracetamol+serratiopeptidase belongs to the class of drugs known as ‘non-steroidal anti-inflammatory drugs’ (NSAID). It is a fixed-dose combination composed of aceclofenac, paracetamol and serratiopeptidase. Aceclofenac+paracetamol+serratiopeptidase is used in the reduction of pain and inflammation due to bone or soft tissue injury, resolution of postoperative inflammation, oedema (swollen tissue with fluid) and pain. Aceclofenac works by blocking the action of an enzyme known as cyclo-oxygenase (COX), which causes pain and swelling in the injured or damaged tissue. Paracetamol acts as a mild analgesic (pain reducer) and antipyretic (fever reducer), which enhances the pain relief action of aceclofenac. Serratiopeptidase is an enzyme which helps in the breakdown of a protein (fibrin) which is formed as a by-product of the clotted blood at the site of injury. It thus causes thinning of the fluids around the site of injury thereby making fluid drainage smoother in the swollen tissue.
