Liofen 40mg Capsule XL contains Baclofen, a centrally acting skeletal muscle relaxant primarily indicated for the treatment of spasticity associated with multiple sclerosis, spinal cord injuries, and other neurological disorders. Baclofen exerts its therapeutic effect by activating GABA_B receptors, which inhibits the transmission of nerve signals in the spinal cord, thereby reducing muscle spasticity and associated pain. Liofen 40mg Capsule XL is formulated as an extended-release preparation, allowing for a sustained and consistent plasma concentration, which improves patient compliance by reducing dosing frequency. It is typically prescribed to alleviate muscle stiffness, spasms, and improve mobility and functional capacity in affected patients. The dosage should be individualized based on clinical response and tolerability, with gradual titration recommended to minimize adverse effects such as drowsiness, dizziness, weakness, and gastrointestinal disturbances. Caution is advised in patients with renal impairment, as Baclofen is primarily excreted unchanged via the kidneys. Abrupt discontinuation should be avoided due to the risk of withdrawal symptoms including hallucinations, seizures, and rebound spasticity. Liofen 40mg Capsule XL should be used under medical supervision, with regular monitoring to optimize therapeutic outcomes and ensure patient safety.
