Title: Non-hyperammonaemia valproate-induced encephalopathy: A case report. Author: Chen L, Xu Z, Huang H. Journal: J Clin Pharm Ther; 2022 Mar; 47(3):415-419. PubMed ID: 34462930. Abstract: WHAT IS KNOWN AND OBJECTIVE: Valproate sodium is an effective antiepileptic drug (AED). Serious adverse effects of valproate sodium are uncommon. This case report illustrates the existence of non-hyperammonaemia valproate-induced encephalopathy. CASE DESCRIPTION: A 47-year-old woman with epilepsy who developed valproate-induced encephalopathy without hyperammonaemia after valproate sodium treatment, and the symptoms completely subsided after withdrawal of valproate sodium. WHAT IS NEW AND CONCLUSION: Early diagnosis and identification of the mechanisms of non-hyperammonaemia valproate-induced encephalopathy are important. Immediate discontinuation of valproate sodium results in rapid resolution of symptoms in these patients.[Abstract] [Full Text] [Related] [New Search]
