Physiological Effects of N-Acetyl Cysteine in Patients With Multiple Sclerosis

The study consists of two arms. The first arm of this study will receive intravenous and oral NAC, a strong antioxidant that increases brain glutathione, which may be beneficial in MS. NAC, is the N-acetyl derivative of the naturally occurring amino acid, L-cysteine. It is a common over-the-counter supplement that is also available as an injectable pharmaceutical that protects the liver in cases of acetaminophen overdose. It has the potential to reduce markers of oxidative damage, protect against cell death, and to increase glutathione in blood, which might be useful in preventing oxidative damage in MS patients. The second arm will be a waitlist control receiving standard MS care. It should be noted that both arms will receive standard of care while enrolled into the study.
