Aceten is a preparation of Acetylcysteine. Acetylcysteine is an antidote for the treatment of acetaminophen overdose. It is the N-acetyl derivative of the naturally-occurring amino acid, cysteine. Acetylcysteine is a mucolytic. The mucolytic action is caused by decrease in viscosity of the bronchial mucous. This is explained by depolymerization, in which the disulphide bonds in macro molecules present in mucous are opened. In addition, Acetylcysteine is a precursor of glutathione. Acetylcysteine is a derivative of the natural amino acid cysteine, which in the body serves as a substrate for the synthesis of glutathione. In addition to the fact that Acetylcysteine is able to normalize a state of glutathione depletion, it can conjugate with different toxic compounds.

INDICATIONS Acetylcysteine is indicated for pulmonary conditions, requiring viscosity reduction of the bronchial secretion to facilitate productive coughing, such as in bronchitis, emphysema, mucoviscidose, and bronchiectasis.

Caution is advised in patients with peptic ulcer disease in their history, especially when using concomitantly other medicines known to irritate the gastrointestinal tract mucous. Mainly at the beginning of the treatment with Acetylcysteine, bronchial secretion can become fluid and increase in volume. When a patient is unable to effectively cough up the secretions, postural drainage and broncho-aspiration have to be performed.
