What types of liver disease do drugs cause?
Comment on this Read 10 Comments
Drugs and chemicals can cause a wide spectrum of liver injury. These include:
Elevated blood levels of liver enzymes
Many drugs cause mild elevations in blood levels of liver enzymes without symptoms or signs of hepatitis. AST, ALT, and alkaline phosphatase are enzymes that normally reside within the cells of the liver and bile ducts. Some drugs can cause these enzymes to leak from the cells and into the blood, thus elevating the blood levels of the enzymes. Examples of drugs that more commonly cause elevations of liver enzymes in the blood include the statins (used in treating high blood cholesterol levels) some antibiotics, some antidepressants (used in treating depression), and some medications used for treating diabetes, tacrine (Cognex), aspirin, and quinidine (Quinaglute, Quinidex).
Since these patients typically experience no symptoms or signs, the elevations of liver enzymes usually are discovered when blood tests are performed as a part of an annual physical examination, as pre-operative screening, or as a part of periodic monitoring for drug toxicity. Typically, these abnormal levels will become normal shortly after stopping the drug, and there usually is no long-term liver damage. With some drugs, low levels of abnormal liver enzymes are common and don't appear to be associated with important (severe or progressive) liver disease, and the patient may continue taking the drug.
