Glenfenac MR 100mg/325mg/250mg Tablet is a combination medication containing Aceclofenac (100mg), Paracetamol (325mg), and Chlorzoxazone (250mg), formulated for the management of musculoskeletal pain and inflammation. Aceclofenac, a non-steroidal anti-inflammatory drug (NSAID), exerts potent analgesic and anti-inflammatory effects by inhibiting cyclooxygenase enzymes, thereby reducing prostaglandin synthesis. Paracetamol provides additional analgesic and antipyretic benefits through central inhibition of prostaglandin synthesis, enhancing overall pain relief. Chlorzoxazone acts as a centrally acting muscle relaxant, alleviating muscle spasms and associated discomfort. The modified-release formulation ensures sustained therapeutic plasma levels, improving patient compliance and symptom control. Glenfenac MR is indicated for conditions such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and acute musculoskeletal disorders where inflammation, pain, and muscle spasm coexist. Caution is advised in patients with hepatic, renal, or cardiovascular impairment, and it should be used under medical supervision to monitor for potential adverse effects including gastrointestinal irritation, hypersensitivity reactions, and CNS disturbances. This combination therapy offers a comprehensive approach to pain management by targeting multiple pathophysiological mechanisms, facilitating improved functional mobility and quality of life in affected individuals.
