Flexabenz ER Capsule belongs to the group of medicines called 'muscle relaxant' used to reduce and relieve the muscle spasm or excessive muscle tension occurring in various illnesses. Muscle spasm is the sudden involuntary contractions of the muscle, which can be painful and uncomfortable. When the nerve impulses that control the muscle movements are damaged or interrupted, it could lead to muscle spasms. 

The Flexabenz ER Capsule contains 'cyclobenzaprine' which works by relieving muscle spasm through action on the central nervous system at the brain stem and helps relieve pain and improve muscle movements. Flexabenz ER Capsule works on the spinal cord and brain, thereby maintaining muscle strength and relieving muscle spasms or stiffness.
