Compound of angiotensin receptor blocker and levosimendan and use of compound

Abstract

The invention provides a compound of an angiotensin receptor blocker and levosimendan and use of the compound. The compound is composed of the angiotensin receptor blocker and levosimendan, which can be mixed directly or be connected indirectly through a hydrogen bond, wherein a co-crystallized sodium hydrate formed by connection through hydrogen bond is more stable in property; and the pharmacokinetic properties are improved significantly; the action mechanisms of the angiotensin receptor blocker and the levosimendan are different, but the formed compound has an unexpected synergistic effect and has positive application prospects in the anti-heart failure and anti-hypertensive treatment field.

Description

Technical field [0001] The invention belongs to the field of medicines for treating cardiovascular diseases, and particularly relates to a complex of an angiotensin receptor antagonist and levosimendan and its use. Background technique [0002] Heart failure (abbreviated as heart failure) is a complex group of clinical symptoms, which is a severe stage of various heart diseases, with a high incidence rate and a 5-year survival rate similar to that of malignant tumors. The incidence of heart failure in the near future will continue to increase, and it is becoming the most important cardiovascular disease in the 21st century. [0003] According to foreign statistics, the prevalence of central failure in the population is about 1.5% to 2.0%, and it can reach 6% to 10% for people over 65. In the past 40 years, deaths caused by heart failure have increased by 6 times. Heart failure is due to any initial myocardial damage (such as myocardial infarction, cardiomyopathy, hemodynamic overl...

Problems solved by technology

[0011] However, there are currently no clinically effective drugs for the treatment of heart failure and hypertension, and most drugs have unavoidable side effects while relieving symptoms of heart failure and hypertension

And the order of a single drug is prone to tolerance. In order to treat heart failure and hypertension more effectively, some compounds have been developed in the prior art, such as the drug compound containing valsarta...
