Randomized placebo controlled trials of n-acetyl cysteine as adjunct therapy for schizophrenia and bipolar disorder

Abstract

Glutathione is the principal antioxidant of the brain. There is evidence of oxidative stress, lowered brain glutathione and genetic linkage involve glutathione metabolic genes in schizophrenia and bipolar disorder. N-acetyl cysteine (NAC) is a safe, orally bioavailable, precursor of glutathione. NAC has been shown to reverse animal models of oxidative stress, and raises brain glutathione levels.<br /
