The most prominent toxic manifestation linked to acetaminophen use is______________?
Show answer Hide answer
Answer: C. Hepatic necrosis
Explanation
Overdosing on acetaminophen saturates normal metabolic pathways in the human liver. This saturation forces the accumulation of toxic intermediate metabolites that destroy tissue. Consequently, massive acute overdoses lead directly to severe and potentially fatal hepatic necrosis. Acetaminophen is a widely used analgesic and antipyretic medication available over-the-counter. Glutathione depletion in hepatocytes allows toxic metabolites to bind cellular macromolecules. N-acetylcysteine acts as a specific antidote by replenishing hepatic glutathione stores rapidly.
Emergency departments frequently manage accidental or intentional acetaminophen poisoning cases. Early administration of the antidote prevents irreversible liver failure and patient death. Patient education regarding maximum daily doses prevents accidental hepatotoxicity incidents. Respiratory alkalosis is a classic toxic manifestation associated with acute salicylate overdoses. Hemorrhage is a prominent risk linked to anticoagulants or nonsteroidal anti-inflammatory drugs. Gastric ulceration typically results from long-term nonsteroidal anti-inflammatory drug administration.
