چکیده

Encephalopathy is a disorder characterized by altered brain function, which can be attributed to various causes. Encephalopathy associated with metronidazole administration occurs rarely and depends on the cumulative metronidazole dose, and most patients with this condition recover rapidly after discontinuation of therapy. Because metronidazole is metabolized in the liver and can be transported by the cerebrospinal fluid and cross the blood-brain barrier, it may induce encephalopathy even at a low cumulative dose in patients with hepatic dysfunction. We experienced a patient who showed ataxic gait and dysarthric speech after receiving metronidazole for the treatment of hepatic encephalopathy that was not controlled by the administration of lactulose. The patient was diagnosed as metronidazole-induced encephalopathy, and stopping drug administration resulted in a complete recovery from encephalopathy. This case shows that caution should be exercised when administering metronidazole because even a low dose can induce encephalopathy in patients with liver cirrhosis.

Treatment of hepatic encephalopathy with metronidazole.

Neomycin, an antibiotic which is primarily active against the aerobic gut flora and hence reduces the endogenous production of ammonia, is a well-recognised form of treatment for acute or acute on chronic hepatic encephalopathy. This study suggests that metronidazole may be a useful alternative or even adjunctive treatment for such patients. Theoretical and practical justifications for the use ...

Two Different Entities Sharing the Same Metabolic Pathway? We read with interest the recent article by Kim et al on MR imaging features of metronidazole-induced encephalopathy (MIE). They described MR findings from 7 patients treated with metronidazole, 5 of whom suffered from gastrointestinal tract disease. All of the patients showed symmetric signal intensity alterations in the dentate nuclei...
