Trimetazedine with hyperinsulinimea-euoglycemia, N-acetyl cysteine, and vitamin C: A new approach concept for management of aluminum phosphide poisoning.

Abstract

Aluminum phosphide (AlP) is commonly used as a powerful suicidal tool. The exact mechanism of acute toxicity has not been well defined despite high mortality rates as well as its supportive treatment including rapid decontamination and institution of resuscitative measures. The current study aimed to investigate a new combination therapy using trimetazidine, N-acetyl cysteine, vitamin C, and hyperinsulinemia-euglycemia to manage acute AlP poisoning. Acute AlP-induced cardiotoxicity, hemodynamic changes, and hepatotoxicity were evaluated using electrocardiogram, creatinine kinase MB iso-enzyme, troponin-1, blood pressure, random blood glucose level, liver function tests, and histopathological changes in both the heart and liver in a rabbit model of AlP poisoning. The results showed that the new regimen therapy ameliorates the toxic effect of AlP with significant improvement in survival, cardiovascular and hemodynamic parameters in addition to histopathological changes. These results highlight the strong cardioprotective, antioxidant, hepatoprotective effects of the new combined therapy along with correction of hemodynamic changes and hyperglycemia as a potential target in the management of acute AlP poisoning.
