Acute liver injury —
- Acute DILI is the most common form of liver damage caused by drugs.
Drug Induced Hepatitis DIAGNOSIS —
- The diagnosis of DILI can be difficult. The relationship between exposure to the drug and hepatic toxicity is not always clear.
- There is no specific serum biomarker or characteristic histologic feature that reliably identifies a drug as the cause of toxicity
- Exposure must precede the onset of liver injury (although the latent period is highly variable)
- Underlying liver diseaseAcute Myocardial Infarction (AMI) CLINICAL PRESENTATION AND PHYSICAL FINDINGS.

- Liver injury may have recurred more rapidly and severely after repeated exposure.
Classification of liver test abnormalities
- Hepatitis (hepatocellular) ALT 3 x ULN R 5
- Cholestasis ALT 2 x ULN R 2
- Mixed ALT 3 x ULN ALP 2 x ULN R >2 to <5
