Humac Tablet contains Aceclofenac 100mg, a non-steroidal anti-inflammatory drug (NSAID) primarily indicated for the relief of pain and inflammation associated with musculoskeletal disorders such as osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis. Aceclofenac exerts its therapeutic effect by selectively inhibiting cyclooxygenase (COX), leading to a reduction in the synthesis of prostaglandins, which are mediators of inflammation, pain, and fever. This action results in decreased inflammation and alleviation of pain symptoms. Humac Tablet is typically prescribed for short-term management of acute pain and inflammation, including postoperative pain and soft tissue injuries. It is well-tolerated when used as directed but should be administered with caution in patients with a history of gastrointestinal ulcers, bleeding disorders, or renal and hepatic impairment. Common adverse effects may include gastrointestinal discomfort, nausea, dyspepsia, and dizziness. It is contraindicated in patients with known hypersensitivity to aceclofenac, other NSAIDs, or aspirin. Humac Tablet should be used at the lowest effective dose for the shortest duration necessary to minimize potential risks. Patients are advised to consult their healthcare provider before initiating therapy, especially if pregnant, breastfeeding, or taking concomitant medications that may interact with NSAIDs.
