Introduction
Toxic to the liver.
Etiology
- hepatotoxic pharmaceutical agents include:
- acetaminophen (paracetamol)* most common[3]
- allopurinol
- aminosalicylate
- amoxicillin/clavulanate (Augmentin)*
- chlorpromazine
- dapsone
- didanosine
- erythromycin estolate
- estrogens
- ethionamide
- glyburide
- halothane
- isoniazid
- ketoconazole
- methimazole
- methotrexate
- methoxyflurane
- methyldopa
- monoamine oxidase (MAO) inhibitors
- niacin (nicotinic acid)
- nifedipine
- nitrofurantoin
- phenytoin*
- propoxyphene
- propylthiouracil
- pyridium
- rifampin
- salicylates
- sulfonamides
- tamoxifen
- tetracyclines
- trimethoprim/sulfamethoxazole
- valproic acid (sodium valproate)*
- vitamin A
- zidovudine
- >= 10 events/10,000 person years
- 5-10 events/10,000 person years
Epidemiology
- single prescription medication in 73% of subjects
- dietary supplement in 9%
- more that 1 prescription medication (or a prescription plus a dietary supplement) in 18%
- most commonly implicated drug classes were antibiotics (46%) & central nervous system agents, i.e. antiseizure or psychotropic drugs (15%)
- most commonly implicated single agent was amoxicillin/clavulanate (23 cases)
- nitrofurantoin, isoniazid, & trimethoprim/sulfamethoxazole were implicated in 13 cases each
- as defined by specified patterns of serum ALT & serum ALP,
- 57% of cases hepatocellular
- 23% cholestatic
- 20% were mixed
- 69% of patients developed jaundice,
- 60% were hospitalized
- 8% died within 6 months[2]
Pathology
Complications
- hospitalization (59%)
- liver failure requiring liver transplantation (4.5%)
- acetaminophen overdose is most common cause[3]
- death (4.8%)
- persistent liver damage (19%)[6]
Differential diagnosis
- viral hepatitis, especially acute hepatitis C infection
Management
- remove offending agent
- treatment of drug induced hepatotoxicity in the absence of acute liver failure is supportive*
- N-acetylcysteine use is common practice for drug-induced liver injury, but is not evidence based except for acetaminphen toxicity
- prognosis is generally good after removal of offending agent[3]
- refer to liver transplantation center for encephalopathy, coagulopathy, or acute liver failure[3]
* other than acetaminophen
