Drug-induced liver injury (DILI) is a cause of acute and chronic liver disease caused specifically by medications and the most common reason for a drug to be withdrawn from the market after approval. The liver plays a central role in transforming and clearing chemicals and is susceptible to the toxicity from these agents.
Naproxen's medical uses are related to its mechanism of action as an anti-inflammatory compound. [11] Naproxen is used to treat a variety of inflammatory conditions and symptoms that are due to excessive inflammation, such as pain and fever (naproxen has fever-reducing, or antipyretic, properties in addition to its anti-inflammatory activity).

A liver transplant may be required if damage to the liver becomes severe. The need for transplant is often based on low blood pH, high blood lactate, poor blood clotting, or significant hepatic encephalopathy. With early treatment liver failure is rare. [6] Death occurs in about 0.1% of cases. [1] Paracetamol poisoning was first described in ...
NAPQI, also known as NAPBQI or N-acetyl-p-benzoquinone imine, is a toxic byproduct produced during the xenobiotic metabolism of the analgesic paracetamol (acetaminophen). [1] It is normally produced only in small amounts, and then almost immediately detoxified in the liver.
Unlike an overdose in humans, liver damage is rarely the cause of death; instead, methemoglobin formation and the production of Heinz bodies in red blood cells inhibit oxygen transport by the blood, causing asphyxiation (methemoglobinemia and hemolytic anemia). [195] Treatment of the toxicosis with acetylcysteine is recommended. [196]
Metabolism may be abnormal in certain disease states, and accumulation may occur even with normal dosage. [medical citation needed] NSAIDs can also be divided into short-acting (plasma half-life less than 6 h) such as aspirin, diclofenac and ibuprofen and long-acting (half-life approximately greater than 10 h) such as naproxen, celecoxib. [156]
Ultimately, antiarthritic treatments aim to achieve disease remission or low disease activity if remission cannot be achieved and thereby improving quality of life. [ 8 ] The pharmacological effects of antiarthritic medications are typically exerted through the reduction of inflammation, suppression of the immune system and/or aid in easing pain.
Common causes for acute liver failure are paracetamol (acetaminophen) overdose, idiosyncratic reaction to medication (e.g. tetracycline, troglitazone), excessive alcohol consumption (severe alcoholic hepatitis), viral hepatitis (hepatitis A or B—it is extremely uncommon in hepatitis C), acute fatty liver of pregnancy, and idiopathic (without ...
