Methods and compositions for treatment of organophosphate-caused pathology

摘要

A method of treating an organophosphate toxin-caused cardiac abnormality is described which includes administering a pharmaceutical composition including a therapeutically effective amount of a chloride current modulator to an individual subject having a cardiac abnormality caused by intoxication with an organophosphate toxin. The chloride current modulator is effective to modulate a chloride conductance and thereby reduce a symptom or sign of an organophosphate toxin-caused cardiac abnormality, thus treating the toxin-caused cardiac abnormality. Optionally, included is administering a therapeutic agent to inhibit an organophosphate toxin-caused distortion of the action potential of myocytes, support restoration of usual intracellular ionic concentrations, and support an increase in cardiac contractility. A composition according to the invention is described which includes a chloride current modulator; and a therapeutic agent to inhibit an organophosphate toxin-induced distortion of the action potential of myocytes, support restoration of usual intracellular ionic concentrations, and support an increase in cardiac contractility.
