Natalizumab is used to treat relapsing remitting multiple sclerosis (MS). Natalizumab belongs to a group of medicines called disease-modifying therapies which help to slow or reduce the worsening of disability in people with relapsing remitting MS.
- MS is caused by your immune system mistakenly attacking the myelin sheath in your brain and spinal cord.
- It's thought that specific types of B cells and T cells in your body are involved in the attack.
- Natalizumab sticks to the T cells and stops them getting into your brain and spinal cord where they would attack the myelin covering around your nerves.
- This stops inflammation and damage to the nerve, reduces the chance of a flare-up and slows the progression of your disease.
