Inac 50 Tablet contains Diclofenac 50 mg, a nonsteroidal anti-inflammatory drug (NSAID) commonly prescribed for the management of pain and inflammation associated with various musculoskeletal disorders. Diclofenac exerts its therapeutic effect by inhibiting cyclooxygenase (COX-1 and COX-2) enzymes, leading to a reduction in the synthesis of prostaglandins, which are mediators of inflammation and pain. Inac 50 is indicated for the treatment of conditions such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and acute musculoskeletal injuries including sprains and strains. It is also utilized for managing postoperative pain and dysmenorrhea. The recommended dosage should be adhered to strictly to minimize potential adverse effects, which may include gastrointestinal discomfort, nausea, dyspepsia, and, in rare cases, gastrointestinal bleeding or ulceration. Caution is advised in patients with a history of peptic ulcer disease, cardiovascular disorders, renal or hepatic impairment, and those on concurrent anticoagulant therapy. Inac 50 should be taken with food or milk to reduce gastrointestinal irritation. Patients are advised to consult their healthcare provider before initiating therapy, especially if pregnant, breastfeeding, or taking other medications. Regular monitoring may be necessary during prolonged use to assess efficacy and detect any adverse reactions.
