Study of a New Use of an Add-On Drug in the Early Phase of Psychosis (NAC Study)
Larry Seidman, Ph.D.
We are studying a nutritional supplement called N-Acetyl-Cysteine (or
“NAC”) as a novel adjunct in the treatment of symptoms and deficits in
early psychosis. NAC works as an anti-oxidant and is thought to potentially
increase glutathione, which is important to overall brain function, during
a critical period of brain development. Previous research using add-on NAC
treatment in individuals with long term psychosis found improvement of
symptoms and a reduction of side-effects.
What will happen during the study?
The study involves a 28 week, double-blind trial of add-on NAC or placebo
in the treatment of individuals experiencing early psychosis. NAC or
placebo will be taken in the form of an effervescent tablet, which is
dissolved in water.
