Acetaminophen (4'-hydroxyacetanilide), a widely used analgesic/antipyretic drug, is hepatotoxic in large doses, whereas the m-hydroxy isomer of acetaminophen, 3'-hydroxyacetanilide, is not hepatotoxic. Both are oxidized by mouse liver cytochromes P-450 to reactive metabolites that bind covalently to hepatic proteins. Because previous studies have shown that peak levels of liver protein adducts ...
Introduction Metabolic acidosis and coma are common complications of acetaminophen overdose. These affects are usually attributed to massive hepatic necrosis caused by Nacetyl-p-benzoquinoneimine (NAPQI), a toxic metabolite of acetaminophen. We describe an unusual case of lactic acidosis and coma in a patient with acetaminophen toxicity without associated hepatocellular damage as the identifiab...
Renal function tests (serum creatinine, urea and uric acid), were performed in acetaminophen-intoxicated rabbits during hepatoprotective and hepatocurative treatment with Momordica charantia fruit extract. In hepatocurative group, the M. charantia treatment was preceded by acetaminophen intoxication, whereas, in hepatoprotective group, the acetaminophen intoxication was preceded by M. charantia...
N-Acetylcysteine is the drug of choice for the treatment of an acetaminophen overdose. It is thought to provide cysteine for glutathione synthesis and possibly to form an adduct directly with the toxic metabolite of acetaminophen, N-acetyl-p-benzoquinoneimine. However, these hypothese have not been tested in vivo, and other mechanisms of action such as reduction of the quinoneimine might be res...
BACKGROUND The safety and value of acetaminophen (paracetamol) in addition to continuous morphine infusion has never been studied in newborns and young infants. We investigated the addition of acetaminophen to evaluate whether it decreased morphine consumption in this age group after major thoracic (non-cardiac) or abdominal surgery. METHODS A randomized controlled trial was performed in 71 p...
Acetaminophen (paracetamol) is available over the counter in most countries and is widely considered to be safe for use during pregnancy; studies report gestational exposures to acetaminophen that lie in the 46%-65% range. Acetaminophen influences inflammatory and immunologic mechanisms and may predispose to oxidative stress; these and other effects are hypothesized to have the potential to com...
BACKGROUND We investigated acetaminophen use and identify factors contributing to supratherapeutic dosing of acetaminophen in hospitalized patients. METHODS We retrospectively reviewed the electronic health records of adult patients who were admitted to 2 academic tertiary care hospitals (hospital A amd hospital B) from June 1, 2010, to August 31, 2010, and who received acetaminophen during t...
Acetaminophen, a common analgesic/antipyretic, is a frequent cause of acute liver failure in Western countries. The development of an effective cure against acetaminophen hepatotoxicity is crucial. Ethyl pyruvate, an ethyl ester derivative of pyruvic acid, has been identified as a possible candidate against acetaminophen hepatotoxicity in animal experiments. However, the mode of the hepatoprote...
BACKGROUND Several population studies demonstrated an increased risk of allergic rhinitis in patients exposed to acetaminophen. However, no histologic studies have been conducted to assess the relationship between acetaminophen exposure and allergic rhinitis. OBJECTIVE In this study, we investigated the association between chronic acetaminophen exposure and the development of allergic rhiniti...
a mixture of acetaminophen, diphenhydramine hydrochloride and pseudoephedrine hydrochloride is used for the symptomatic treatment of common cold. in this study, a derivative spectrophotometric method based on zero-crossing technique was proposed for simultaneous determination of acetaminophen, diphenhydramine hydrochloride and pseudoephedrine hydrochloride. determination of these drugs was perf...
