Feedback:
Acetylcysteine is used orally to protect liver cells from being damaged during episodes of acetaminophen toxicity because it normalizes hepatic glutathione levels and binds with a reactive hepatotoxic metabolite of acetaminophen. Acetylcysteine is not used for the conversion of cardiac dysrhythmias, for treatment of peptic ulcer disease, or for decreasing bronchospasm.
