Lupirtin Capsule contains Flupirtine 100 mg, a centrally acting non-opioid analgesic with muscle relaxant properties, indicated for the management of moderate to severe acute and chronic pain. Flupirtine exerts its analgesic effect primarily through selective neuronal potassium channel opening, leading to membrane hyperpolarization and reduced neuronal excitability, thereby modulating pain transmission without the typical side effects associated with opioids or nonsteroidal anti-inflammatory drugs (NSAIDs). Lupirtin is effective in conditions such as musculoskeletal pain, postoperative pain, and neuropathic pain, providing symptomatic relief while improving patient functionality. The capsule formulation ensures convenient oral administration with good bioavailability. It is generally well tolerated; however, caution is advised in patients with hepatic impairment due to the risk of hepatotoxicity. Liver function tests should be monitored regularly during prolonged therapy. Contraindications include known hypersensitivity to Flupirtine or any excipients, severe liver disease, and concomitant use with other hepatotoxic drugs. Common adverse effects may include dizziness, nausea, and fatigue. Lupirtin Capsule should be used under medical supervision, adhering to recommended dosages to minimize risks and optimize therapeutic outcomes in pain management.
