The Role of Levosimendan as Inotropic Agent in Acute Aluminum Phosphide-induced Cardiotoxicity

To evaluate the potential role of levosimendan as an inotropic agent in aluminum phosphide-induced cardiotoxicity

Aluminum phosphide (ALP) is a well-known fumigant known also as rice pill or wheat pill. It is considered an ideal pesticide since it is effective to preserve stored grains against insects and rodents without leaving residues, in addition to its availability and low cost. In Egypt, it has become a common method of suicide over the last few years because it is cheap and easily accessible. Cardiomyocytes are one of the main targets for ALP. ALP-induced cardiotoxicity involves detrimental effects such as direct myocardial tissue damage, hypoperfusion, myocarditis, pericarditis, and arrhythmias leading to circulatory failure. Levosimendan, an inotropic agent, enhances cardiac contractility through calcium sensitization with minimal oxygen demand and, in turn, decreases the risk of arrhythmia. However, limited studies have investigated the role of levosimendan in the treatment of ALP induced cardiotoxicity.
