Overview
Norflex 100mg Tablet contains orphenadrine citrate 100mg as its sole active ingredient, a centrally-acting muscle relaxant with anticholinergic properties. It is used to relieve the pain and spasm associated with acute musculoskeletal conditions, usually as an adjunct to rest, physiotherapy, and other supportive measures.
Orphenadrine is thought to act mainly within the central nervous system, where it blocks NMDA receptors and reduces the excessive nerve signalling that drives muscle spasm; it also has anticholinergic and mild local anaesthetic-like properties that contribute to its muscle-relaxant and analgesic effect, though it does not act directly on skeletal muscle itself.
How it Works
Orphenadrine reduces muscle spasm indirectly through central NMDA-receptor blockade rather than by acting directly on muscle fibres, and its anticholinergic properties further contribute to muscle relaxation and a mild analgesic effect, easing the discomfort associated with musculoskeletal spasm.
Directions for Use
Take Norflex 100mg Tablet with food or a glass of water to reduce the chance of stomach upset, at approximately the same times each day. Swallow the tablet whole, and do not exceed the dose prescribed by your doctor.
Dosage
The usual adult dose of Norflex 100mg Tablet is one tablet (100mg) taken twice daily, morning and evening, though your doctor may adjust this depending on your response and the severity of your symptoms. Treatment is generally intended for short-term use during an acute episode of muscle spasm.
