Contraindications of Aceclofenac 100mg + Paracetamol 325mg:
Hypersensitivity. Moderate to severe renal or hepatic impairment; severe heart failure; pregnancy (third trimester).
Mechanism of Action of Aceclofenac 100mg + Paracetamol 325mg:
Aceclofenac is a phenylacetic acid derivative that inhibits synthesis of the inflammatory cytokines interleukin-1b and tumour necrosis factor, and inhibits prostaglandin E2 production. It increases glycosaminoglycans (GAG) synthesis, the principal macromolecule of the extracellular matrix, which aids in repair and regeneration of articular cartilage. Thus, aceclofenac has +ve effects on cartilage anabolism combined with modulating effect of matrix catabolism. 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. Absorption: Aceclofenac: Rapidly absorbed; almost 100% bioavailability; peak plasma levels reached about 1.25-3 hr after oral admin. Distribution: Aceclofenac: >99.7% bound to plasma proteins; distributes into synovial fluid. Paracetamol: Distributes throughout most fluids of the body. Metabolism: Aceclofenac: Probably metabolised by CYP2C9; average plasma elimination half-life: 4-4.3 hr. Paracetamol: Mainly metabolised hepatically; plasma elimination half-life: 1-4 hr. Excretion: Aceclofenac: About two-thirds of the administered dose is removed in the urine, mainly as conjugated hydroxymetabolites. Paracetamol: Most metabolites are removed in the urine within 24 hr.

GI disease; renal or hepatic impairment; alcohol-dependent patients; asthma or allergic disorders; haemorrhagic disorders; hypertension; cardiac impairment. Elderly. Caution when driving or operating machinery. Monitor renal and hepatic function and blood counts during long term treatment. Persistently elevated hepatic enzyme levels may require drug withdrawal.
