Abstract: Cordemcura has a dose-dependent inotropic effect in the Langendorff-perfused guinea pig heart, in the isolated spontaneously active atria of the guinea pig as well as in the isolated electrically stimulated rabbit papillary muscle. Tachyphylaxy symptoms and arrhythmogene side-effects have not been observed. The dose-dependent coronardilatory effect caused by Cordemcura as observed at the isolated heart of a guinea-pig appears intensely. The positive inotropic effect by Cordemcura on an isolated electrically stimulated papillary muscle of a rabbit is linked with a significant decrease of the relaxation time t2, whereas there is no change in the time to peak force t1. Both mean velocity of force development S1 as well as the mean velocity of relaxation S2 are increased by Cordemcura.
