ACUTE HEPATITIS AFTER TETRAHYDROAMINOACRIDINE ADMINISTRATION FOR ALZHEIMERS-DISEASE

Tetrahydroaminoacridine administration has been proposed as a treatment for Alzheimer’s disease. Although recent studies have shown that tetrahydroaminoacridine administration can be associated with mild or moderate liver dysfunction, to our knowledge, no case of symptomatic hepatitis with severe liver lesions has heretofore been reported. We describe a patient who developed jaundice after receiving tetrahydroaminoacridine for three weeks. Histologic examination showed extensive hepatocellular necrosis. Tetrahydroaminoacridine withdrawal was followed by the disappearance of jaundice within a few days and complete recovery within 5 weeks. This case shows that tetrahydroaminoacridine administration can induce marked liver cell necrosis resulting in symptomatic acute hepatitis. © 1990 Raven Press, Ltd., New York.
