Tiglutik Overview

Reviewed: September 17, 2018
Updated: 

Tiglutik is a prescription medication used to treat amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease. ALS is a rare disease that affects nerve cells that are responsible for controlling muscle movement. It is a progressive condition, meaning that people living with ALS experience a continuing decline in muscle strength.

Tiglutik belongs to a group of drugs called benzothiazoles. The exact way Tiglutik works is not known. It is thought that it may inhibit the release and signaling of glutamate (a neurotransmitter that may be in excess in people with ALS) and therefore reduce the damage caused by glutamate and slow the progression of ALS.

This medication comes in liquid suspension form and is taken every 12 hours, at least 1 hour before or 2 hours after a meal.

Common side effects include numbness or tingling around the mouth, weakness, nausea, decreased lung function, high blood pressure, and stomach pain.
