Acetilcystein (N-acetil-L-cistein, NAC), je lek koji se koristi za lečenje predoziranja paracetamolom (acetaminofenpm) i za razvodnjavanje guste sluzi kod obolelih od bronhopulmonarnih bolesti, poput zapaljenja pluća i bronhitisa.^[7] Može se primeniti intravenski, preko usta, ili inhalacijom.^[7] Koristi se i kao dodatak hrani.^[8]^[9]

Druge upotrebe uključuju sulfatno snabdevanje kod oboljenja kao što su autizam, gde cistein i srodne sumporne amino kiseline mogu da budu iscrpljene.^[10]

Acetilcistein je derivat cisteina; jedna acetil grupa je vezana za atom azota. Ovo jedinjenje je u prodaji kao dijetetski suplement za koji se smatra da deluje kao antioksidans i da štiti jetru. On se koristi kao lek za kašalj jer raskida disulfidne veze u sluzi i utečnjava je, te se lakše iskašljava. To svojstvo je takođe koristno u redukovanju abnormalno guste sluzi kod obolelih od cistične i pulmonarne fibroze.
