Harnac-P Oral Suspension is a combination analgesic and anti-inflammatory medication containing Aceclofenac 100 mg and Paracetamol 250 mg per 5 ml. Aceclofenac, a non-steroidal anti-inflammatory drug (NSAID), exerts its effect by inhibiting cyclooxygenase enzymes, thereby reducing the synthesis of prostaglandins responsible for pain and inflammation. Paracetamol, a widely used analgesic and antipyretic agent, works primarily through central inhibition of prostaglandin synthesis, providing effective relief from mild to moderate pain and fever. This formulation is indicated for the management of acute musculoskeletal pain, osteoarthritis, rheumatoid arthritis, dental pain, and other inflammatory conditions where both analgesic and anti-inflammatory effects are desired. Harnac-P Oral Suspension offers a convenient liquid dosage form suitable for patients who have difficulty swallowing tablets or require flexible dosing. The combination enhances analgesic efficacy while minimizing the dose of each component, potentially reducing the risk of adverse effects associated with higher doses of individual drugs. Caution is advised in patients with a history of hypersensitivity to NSAIDs, hepatic or renal impairment, and gastrointestinal disorders. It should be used under medical supervision, adhering to recommended dosages to avoid toxicity.
