Tizanidine is a short-acting muscle relaxer. It works by blocking nerve impulses (pain sensations) that are sent to your brain. Tizanidine is used to treat spasticity by temporarily relaxing muscle tone. Tizanidine may also be used for purposes other than those listed in this medication guide.
Zanaflex is a short-acting muscle relaxant, classified as an adrenergic agonist. It works by affecting alpha 2 receptors in the brain and spinal cord, which blocks nerve signals from reaching muscles and in turn produces muscle relaxation. This is especially helpful for treating patients with Multiple Sclerosis or a spinal cord injury.
