Tizanidine HCl 4 mg is a muscle relaxant medication that is commonly prescribed to treat muscle spasms caused by conditions such as multiple sclerosis, spinal cord injury, or stroke. It belongs to a class of medications known as alpha-2 adrenergic agonists, which work by stimulating certain receptors in the brain and spinal cord to produce a relaxing effect on muscles.
How Does Tizanidine HCl 4 mg Work?
Tizanidine HCl 4 mg works by binding to alpha-2 adrenergic receptors in the brain and spinal cord, which are involved in the regulation of muscle tone. By stimulating these receptors, tizanidine increases the activity of inhibitory neurons, which reduces the excitability of muscle fibers and leads to a decrease in muscle spasms and muscle tone.
