Application

Tizanidine hydrochloride has been used for developing spectrophotometric methods for the validation of skeletal muscle relaxants.

Biochem/physiol Actions

Tizanidine hydrochloride is known to function as a skeletal muscle relaxant that acts centrally. Furthermore, this relaxant functions at spinal and supraspinal levels to block excitatory interneurons. This drug is used for the symptomatic relief of spasticity and painful muscle spasms.
α2-adrenoceptor agonist.

Although intrathecal clonidine produces pronounced analgesia, antinociceptive doses of intrathecal clonidine produce several side effects, including hypotension, bradycardia, and sedation. Intrathecal tizanidine, another alpha(2)-adrenergic agonist, has provided antinociception without producing pronounced hemodynamic changes in animal studies. However, it has been
