Application:
6-(4-Aminophenyl)-4,5-Dihydro-5-Methyl-3(2H)-Pyridazinone (CAS: 36725-28-7) is an intermediate of Levosimendan (CAS: 141505-33-1). Levosimendan was introduced in Sweden as an i.v. infusion for the treatment of acute heart failure or refractory symptoms of chronic heart failure in cases where conventional treatment (e.g., diuretic or ACE inhibitor) is not sufficient. It also activates ventricular and arterial adenostne triphosphate-regulated potassium channels which causes vasodilatation in vascular smooth muscle and protects myocardium against infarction. Its low phosphodiesterase III inhibiting activity is probably not responsible for its positive inotropic, lusitropic and dilating effects. Unlike other cardiotonic drugs, levosimendan is able to produce positive inotropic effects without prolonging myocardial relaxation or increasing the incidence of malignant arrythmias. It was clinically shown to have a lower risk of mortality in patients with heart failure when compared to placebo and dobutamine. Since it has a larger potential, levosimendan is currently under further clinical evaluation as a chronic treatment for congestive heart failure.
