Product Description

Introduction to Tysabri 300mg Injection

Tysabri 300mg injection contains an active component such as Natalizumab. This medication is a monoclonal antibody medication used to treat multiple sclerosis (MS) and Crohn’s disease. Multiple sclerosis (MS) is a chronic autoimmune disease of the central nervous system, causing communication problems between the brain and the rest of the body. Crohn’s disease is a chronic inflammatory condition affecting the gastrointestinal tract. This medication-targeted mechanism of action reduces inflammation by blocking specific immune cell movement, thereby mitigating potential damage to the central nervous system in MS or reducing inflammation in the gut in Crohn’s disease. By effectively managing disease activity, Tysabri 300mg injection can improve patients’ overall quality of life by reducing symptoms, decreasing the frequency of relapses, and potentially delaying disability progression.

Tysabri 300mg injection can cause hypersensitivity reactions in some individuals. Patients with a history of hypersensitivity to this medicine or its components should avoid its use, and individuals at higher risk need screening. This medication is contraindicated in patients with a history of progressive multifocal leukoencephalopathy (PML) or who are positive for the JC virus, as they are at a higher risk of developing PML during treatment. It should not be used in patients with active infections, especially serious or opportunistic infections. Its safety and effectiveness in pediatric patients (children and adolescents) have not been fully established. Therefore, its use in this population is generally not recommended.

Therapeutic Effects of Tysabri 300mg Injection

Tysabri 300mg injection is a monoclonal antibody that works by targeting a protein called α4-integrin on certain immune cells. By binding to α4-integrin, it prevents these immune cells from crossing the blood-brain barrier in multiple sclerosis or migrating into the gut lining in Crohn’s disease. This action reduces inflammation and helps protect the central nervous system in MS, leading to fewer relapses and slowed disease progression. Overall, its mechanism of action modulates the immune response, providing therapeutic benefits in treating multiple sclerosis and Crohn’s disease.
