Flexifen 10 MG contains baclofen, a centrally acting skeletal muscle relaxant and antispastic agent. 1 It works primarily at the spinal cord level by stimulating GABA-B receptors, which helps to reduce muscle stiffness, spasms, and pain associated with conditions like multiple sclerosis, spinal cord injuries, rheumatic disorders, and cerebrovascular accidents. It is used to alleviate spasticity, including flexor spasms, pain, clonus, and muscular rigidity
