Acetaminophen overdose causes toxicity in liver and extrahepatic tissues. Although it is well established that cytochrome P450 enzymes play a critical role in the metabolic activation of acetaminophen, it is not yet clear whether acetaminophen toxicity in extrahepatic tissues is a consequence of hepatic biotransformation. The aim of this study was to determine whether extrahepatic acetaminophen...

Puzzling situation of acetaminophen toxicity in a referral hospital, Tehran, Iran Acetaminophen carries a higher risk of overdose. A puzzling situation of acetaminophen toxicity was encouraging enough to explore the epidemiologic situation of acetaminophen toxicity and its outcomes among patients acquired poisoning. This cross-sectional study retrospectively reviewed the medical r...

The analgesic and antipyretic compound acetaminophen (paracetamol) is one of the most used drugs worldwide. Acetaminophen overdose is also the most common cause for acute liver toxicity. Here we show that acetaminophen and many structurally related compounds bind quinone reductase 2 (NQO2) in vitro and in live cells, establishing NQO2 as a novel off-target. NQO2 modulates the levels of acetamin...

PURPOSE The present study examines the relationship between the dose of acetaminophen reported to have been ingested by patients and the occurrence of serum acetaminophen levels above the 'possible toxicity' line in patients presenting at the hospital after acetaminophen overdose. The prognostic value of patient-reported dosage cut-offs of 8, 10 and 12 g was determined. METHODS This retrospec...

Acetaminophen is widely used in children, because its safety and efficacy are well established. Although the risk of developing toxic reactions to acetaminophen appears to be lower in children than in adults, such reactions occur in pediatric patients from intentional overdoses. Less frequently, acetaminophen toxicity is attributable to unintended inappropriate dosing or the failure to recogniz...
