A synthetic N-acetyl derivative of the endogenous amino acid L-cysteine, a precursor of the antioxidant enzyme glutathione. Acetylcysteine reduces disulfide bonds in mucoproteins, resulting in liquification of mucus. The agent also regenerates liver stores of glutathione. Some evidence suggests that acetylcysteine may exert an anti-apoptotic effect due to its antioxidant activity.
