Tizanidine to Manage and Relieve Muscle Spasticity
Tizanidine is an inexpensive medication used as a muscle relaxant to manage and relieve muscle spasticity and increased muscle tone due to multiple sclerosis, stroke, brain, or spinal injury. It belongs to the class of drugs known as alpha 2 adrenoceptor agonist.
What condition does Tizanidine treat?
Tizanidine is a prescription drug prescribed by doctor for the treatment and management of muscle spasticity associated with conditions like:
Multiple sclerosis: Is a common disabling disease among young adults. It’s a disease of the spinal cord and the brain that can present with almost anything from simple fatigue to immediate paralysis. The nerves of people with MS do not function properly and may likely experience loss of muscle coordination, vision, speech, and bladder control function. This disease is caused by an overactive immune system turning on the body’s own tissue.
Stroke: Are caused by abrupt blockage or bleeding of arteries leading to the brain. Stroke can be fatal. It is a potentially life-changing event that can have lasting emotional and physical effects.
- Brain and spinal cord injury
How does Tizanidine work?
- As an alpha-2-adrenoceptor agonist, Tizanidine works as a muscle relaxant by blocking the alpha-2-adrenoceptor in the central nervous system. Alpha-2-adrenoceptor agonist is a class of sympathomimetic agent that selectively stimulates the alpha adrenoceptor. The effects of Tizanidine on the alpha-2adrenoceptor reduces the activity of the nerve cells in the brain and spinal cord that control the muscle thus also reducing the contraction and tension in the muscle.
- This medicine has been used predominantly in the management of spasticity, but it also proved to be useful in treating painful conditions such as headache disorder. It has been found to be effective in the treatment of chronic daily headache.
- In conditions where there is disturbing and painful muscle spasm, this medicine reduces muscle stiffness to enable patients to undergo rehabilitation to increase their mobility.
- Tizanidine is found to be more tolerable than diazepam and Baclofen for it causes less muscle weakness and a lower incidence of sedation.
What is the dosage of Tizanidine?
- Your dose and the duration of treatment depends on your condition, the severity of your condition, and the strength of the medicine.
- The recommended starting dose in treating muscle spasm among adults is 2mg every 6-8 hours or as needed. Your doctor may increase your dose by 2 to 4mg after 1 to 4 days. The maximum recommended dose is 3 doses within 24 hours. Do not take more than 36mg within 24-hours.
