Aceclofenac is a phenylacetic acid derivative that inhibits synthesis of the inflammatory cytokines and inhibits prostaglandin production. Paracetamol has analgesic and antipyretic action with weak anti-inflammatory activity. It produces analgesia by increasing pain threshold and antipyresis by acting on the hypothalamic heat-regulating centre.

Tramadol combines with the opoiod receptors in the brain and spinal cord, which blocks the transmission of pain signals sent by the nerves to the brain. Paracetamol has analgesic and antipyretic action with weak anti-inflammatory activity. It produces analgesia by increasing pain threshold and antipyresis by acting on the hypothalamic heat-regulating centre.
