Tiglutik is indicated for the treatment of amyotrophic lateral sclerosis (ALS), a progressive neurodegenerative disease affecting nerve cells in the brain and spinal cord that control voluntary muscle movement.
Tiglutik contains riluzole, which reduces the activity of glutamate, a neurotransmitter involved in nerve cell communication. By decreasing glutamate levels, it may help reduce excitotoxicity that contributes to nerve cell damage in ALS.
Regular liver function monitoring is required during treatment. Common side effects may include nausea, diarrhea, abdominal pain, dizziness, and weakness. Patients with severe liver disease should not use this medication. Inform your doctor of all current medications before starting treatment.
