Acetylcysteine is extensively liver metabolized, CYP450 minimal, urine excretion is 22–30% with a half-life of 5.6 hours in adults and 11 hours in newborns. [medical citation needed] Acetylcysteine is the N-acetyl derivative of the amino acid L-cysteine, and is a precursor in the formation of the antioxidant glutathione in the body.
Thiamphenicol glycinate acetylcysteine (TGA) is a pharmaceutical drug that is a combination of thiamphenicol glycinate ester (TAFGE), which is a derivative of the antibiotic thiamphenicol, and N-acetylcysteine (NAC), which is a mucus-thinning drug. Upon contact with tissue esterases, TGA releases both TAFGE and NAC.

This line is referred to as the treatment line and starts at 150 μg/mL at 4 hours. It is the usual line used in the United States to determine treatment of acetaminophen overdose after the publication of the NAC study ...

A metanalysis conducted on 2753 patients with moderate COPD shows that the efficacy and safety profile of erdosteine is superior to that of other muco-regulatory drugs (carbocysteine and N-acetylcysteine). Furthermore, erdosteine was the only mucolytic able to reduce the risk of hospitalization due to COPD exacerbations. [9] Other activities
