Patient summary
Zanaflex is tizanidine 2mg and 4mg tablets for muscle spasticity, a centrally acting alpha-2 agonist rather than a direct muscle relaxant.
Mechanism of action
Tizanidine is a centrally acting alpha-2 adrenergic agonist. It reduces spasticity by increasing presynaptic inhibition of motor neurons. By acting on the spinal cord, it decreases the excitability of muscle neurones, thereby reducing muscle tone without weakening muscle strength.
Zanaflex contains tizanidine, a common treatment for muscle spasticity. The same active ingredient is also sold as Sirdalud, a well-known brand produced by manufacturers such as Novartis. This medication is supplied as a tablet, available in strengths of 2mg and 4mg.
