Inac 25mg Injection contains Diclofenac 25mg, a nonsteroidal anti-inflammatory drug (NSAID) indicated for the management of acute pain, inflammation, and swelling associated with musculoskeletal disorders, postoperative conditions, and other inflammatory diseases. Diclofenac exerts its therapeutic effect by inhibiting cyclooxygenase (COX-1 and COX-2) enzymes, leading to a reduction in prostaglandin synthesis, which mediates inflammation and pain. Inac 25mg Injection is administered intramuscularly or intravenously for rapid onset of action, making it suitable for patients requiring prompt relief from moderate to severe pain and inflammation. It is commonly used in conditions such as rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, and acute gout attacks. The dosage should be individualized based on the severity of symptoms and patient response, with careful monitoring to minimize potential adverse effects. Common side effects include gastrointestinal discomfort, nausea, dizziness, and injection site reactions. Caution is advised in patients with a history of peptic ulcers, cardiovascular disease, renal or hepatic impairment, and hypersensitivity to NSAIDs. Inac 25mg Injection should be used under medical supervision, adhering to recommended dosing guidelines to ensure safety and efficacy.
