Nowadays drug-induced hepatotoxicity is urgent problem worldwide. Currently more than 1000 drugs are hepatotoxic and most often are the reason of acute fulminant hepatitis and hepatocellular failure, the states requiring liver transplantation. The paracetamol induced liver toxicity is related with accumulation of its toxic metabolite N-acetyl-p-benzoquinone imine (NAPQI), which is the free radical and enhances peroxidation of lipids, disturbs the energy status and causes death of hepatocytes. During our research we investigated and assessed the efficacy of acetylcysteine, corvitin and their combination in rat model of paracetamol induced acute toxic hepatitis...

CONTEXT: Paracetamol (acetaminophen or APAP) is the most common pharmaceutical exposure in the US. Elevations in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels indicate hepatic toxicity. AST and ALT levels rise in similar proportions but later decline at different rates, with AST falling more rapidly than ALT. OBJECTIVE: To determine whether the AST/ALT ratio can indicate that a patient has passed the time of peak AST concentration. METHODS: We retrospectively identified cases of patients hospitalized for acute APAP poisoning by querying the pharmacy database of all patients treated with acetylcysteine (NAC) from January 1, 2001 to March 19, 2013...
