Zeromac-P Tablet is a combination analgesic and anti-inflammatory medication containing Aceclofenac 100 mg and Paracetamol 325 mg, formulated for the effective management of pain and inflammation associated with musculoskeletal disorders, osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis. Aceclofenac, a non-steroidal anti-inflammatory drug (NSAID), exerts its effect by inhibiting cyclooxygenase enzymes, thereby reducing the synthesis of prostaglandins responsible for inflammation and pain. Paracetamol complements this action by providing analgesic and antipyretic effects through central inhibition of prostaglandin synthesis. This synergistic combination offers enhanced pain relief with a potentially lower risk of gastrointestinal side effects compared to higher doses of NSAIDs alone. Zeromac-P is indicated for the relief of mild to moderate pain, including dental pain, postoperative pain, and musculoskeletal discomfort. It should be used with caution in patients with hepatic, renal, or cardiovascular impairment and is contraindicated in individuals with known hypersensitivity to either component. The medication should be administered as directed by a healthcare professional, with attention to dosing intervals to minimize adverse effects. Regular monitoring is advised during prolonged therapy to detect any potential side effects such as gastrointestinal irritation, liver enzyme alterations, or hypersensitivity reactions.
