Which drugs can cause drug induced liver injury?
Other drugs that can lead to liver injury include:
- Amiodarone.
- Anabolic steroids.
- Birth control pills.
- Chlorpromazine.
- Erythromycin.
- Halothane (a type of anesthesia)
- Methyldopa.
- Isoniazid.
What is drug induced liver disease?
Drug-induced hepatitis is a redness and swelling (inflammation) of the liver that is caused by a harmful (toxic) amount of certain medicines. The liver helps to break down certain medicines in your blood. If there is too much medicine in your blood for your liver to break down, your liver can become badly damaged.
How is drug induced liver injury diagnosed?
Drug induced liver injury is a diagnosis of exclusion and relies upon clinical judgment and knowledge about the potential of the agent to cause liver injury versus the likelihood that other forms of liver diseases are the cause.
What are the clinical manifestations of drug induced liver injury?
The majority of cases of DILI are acute illnesses that resolve quickly after the offending medication is stopped. The clinical symptoms are similar to other forms of hepatitis or cholestasis where fatigue, nausea, malaise, pruritus, and jaundice predominate.
What causes drug-induced liver injury?
Drug-induced liver injury (DILI; also known as drug-induced hepatotoxicity) is caused by medications (prescription or OTC), herbal and dietary supplements (HDS), or other xenobiotics that result in abnormalities in liver tests or in hepatic dysfunction that cannot be explained by other causes.
How do drugs affect the liver?
For example, drugs may damage the liver by directly damaging liver cells (hepatocellular), by blocking the flow of bile out of the liver (cholestatic), or by doing both.
What is idiosyncratic liver injury?
Idiosyncratic drug-induced liver injury (DILI) is a rare disease that develops independently of drug dose, or route or duration, of administration. Furthermore, idiosyncratic DILI is not a single disease entity, but rather a spectrum of rare diseases with varying clinical, histologic, and laboratory features.
Are ALT and AST liver enzymes?
ALT is an enzyme found in the liver that helps convert proteins into energy for the liver cells. When the liver is damaged, ALT is released into the bloodstream and levels increase. Aspartate transaminase (AST). AST is an enzyme that helps metabolize amino acids.
Are all drugs metabolized in the liver?
Most drugs must pass through the liver, which is the primary site for drug metabolism. Once in the liver, enzymes convert prodrugs to active metabolites or convert active drugs to inactive forms. The liver’s primary mechanism for metabolizing drugs is via a specific group of cytochrome P-450 enzymes.
What is a idiosyncratic reaction?
Idiosyncratic drug reactions may be defined as adverse effects that cannot be explained by the known mechanisms of action of the offending agent, do not occur at any dose in most patients, and develop mostly unpredictably in susceptible individuals only.
What is intrinsic liver disease?
Intrinsic DILI refers to liver toxicity induced by a drug in a predictable and dose-related manner (e.g., acetaminophen [APAP]); idiosyncratic DILI, which occurs less frequently, is associated with a less consistent dose-toxicity relationship and a more varied presentation.
What causes drug-related fibrosis of the liver?
There may be multiple explanations for these findings, some of which may be related to true drug injury, whereas others may be related to underlying liver disease or other comorbidities. Advanced fibrosis can be caused by drugs such as amiodarone 18 and nitrofurantoin 19, 20 or may be the result of an underlying chronic liver disease.
What are the drug-related causes of hepatitis?
Drug-induced chronic hepatitis is rare, but fibrosis and cirrhosis can occur with drugs such as methotrexate, while autoimmune hepatitis-like disease can result with drugs such as minocycline. In some instances, drug-related cholestatic injury can be prolonged and can lead to ductopenia.
What are the drugs that cause liver problems?
Allopurinol, gold, procainamide, quinidine, methyldopa, diclofenac, diltiazem, BCG therapy for cancer, nitrofurantoin, mesalamine, phenylbutazone (veterinary use, use in humans limited due to side effect of aplastic anaemia) 78 Evaluation of liver biopsy for adverse drug reaction is one of the most challenging problems in liver pathology.
What is the mechanism of drug-induced liver injury?
It is widely recognised that drug-induced liver injury (DILI) is mediated by two chief mechanisms: intrinsic and idiosyncratic hepatoxicity. Intrinsic hepatotoxins cause hepatocellular damage in a predictable dose-dependent manner directly by the drug or indirectly by its metabolite.
