[Effect of mexidol, emoxypine, and dimephosphon on electrophysiological effects of nibentan].
Mexidol, emoxypine, and dimephosphon decrease the acute toxicity of nibentan in mice. In the experiments on cats, these drugs reduced the negative dromotropic action of nibentan and prevented an increase in the effective refractory period of the atrioventricular node and ventricles, in the QT interval length, and in the ventricular excitation threshold.
