Tizanidine is a muscle relaxant prescribed to manage muscle spasms caused by certain conditions such as spinal cord injury, multiple sclerosis. It works by helping to relax the muscles. Tizanidine is prescribed for medical issues such as, degenerative disc disease, herniated discs, a mild case of scoliosis, and fibromyalgia all of which cause chronic back pain.
How does Tizanidine work?
It is a short-acting muscle relaxant. Tizanidine works by blocking nerve impulses (pain signals) that are sent to your brain
Tizanidine is an α2-adrenergic agonist which reduces muscular spasticity by increasing presynaptic inhibition of motor neurons. This drug affects the polysynaptic pathways, and thus reduces facilitation of spinal motor neurons.
About 95% of this drug is metabolized in the liver. In elderly patients with renal insufficiency, the metabolism of this drug is reduced to 50%.
