abstract = {N-acetylcysteine (NAC) is a synthetic derivative of the amino acid L-cysteine with well-established antioxidant, mucolytic, and cytoprotective properties. Initially introduced as a mucolytic agent, NAC later became the standard antidote for acetaminophen (paracetamol) poisoning because of its ability to replenish intracellular glutathione stores [1,2]. Over recent decades, its therapeutic applications have expanded into pulmonology, hepatology, nephrology, psychiatry, reproductive medicine, and oncology [3,4]. NAC exerts its effects through multiple mechanisms, including glutathione restoration, direct scavenging of reactive oxygen species, modulation of inflammatory pathways, and regulation of cellular signaling [3,5]. While strong clinical evidence supports its use in acetaminophen overdose and selected respiratory diseases, evidence for many emerging indications remains limited or inconsistent [6]. This review examines the pharmacology, mechanisms of action, clinical applications, safety profile, and therapeutic effectiveness of NAC across a broad range of medical conditions.},
