Pharmaceutical composition
The present invention relates to a pharmaceutical composition comprising: (a) at least one neutral endopeptidase inhibitor or a pharmaceutically acceptable salt or ester thereof, (b) at least one compound represented by formula (I) or a pharmaceutically acceptable salt or ester thereof, and a pharmaceutically acceptable carrier. Combined administration showed better medicinal effects than separate administration.
1. A pharmaceutical composition comprising:
(a) at least one neutral endopeptidase inhibitor selected from sodium 4-(((2S,4R)-1-([1,1′-biphenyl]-4-yl)-5-ethoxy-4-methyl-5-oxopentan-2-yl) amino)-4-oxobutyrate,
potassium 4-(((2S,4R)-1-([1,1′-biphenyl]-4-yl)-5-ethoxy-4-methyl-5-oxopentan-2-yl) amino)-4-oxobutanoate, and
ammonium 4-(((2S,4R)-1-([1,1′-biphenyl]-4-yl)-5-ethoxy-4-methyl-5-oxopentan-2-yl) amino)-4-oxobutanoate;
(b) a compound of formula (1K);
and
a pharmaceutically acceptable carrier.
2. A pharmaceutical kit comprising separate containers, wherein a first container of the containers comprises:
(a) a first pharmaceutical composition comprising a first pharmaceutically acceptable carrier, and at least one neutral endopeptidase inhibitor defined as in claim 1 ;
and a second container of the containers comprises:
(b) a second pharmaceutical composition comprising a second pharmaceutically acceptable carrier, and the compound of formula (1K) defined as in claim 1 .
3. The pharmaceutical composition according to claim 1 , wherein a mass ratio of the at least one neutral endopeptidase inhibitor to the compound of formula (1K) is (0.5-10) : 1.
4. (Withdrawn and Previously Presented) A medicament comprising the pharmaceutical composition according to claim 1 .
5. A method for preparing the medicament of claim 4 , comprising combining
(a) the at least one neutral endopeptidase inhibitor;
(b) the compound of formula (1K); and
the pharmaceutically acceptable carrier.
6. The pharmaceutical composition according to claim 1 , wherein the compound of formula (1K) is selected from at least one of the group consisting of an amorphous, crystalline form I, crystalline form II, crystalline form III, and crystalline form IV of the compound of formula(1K).
7. The pharmaceutical kit according to claim 2 , wherein a mass ratio of the (a) to the (b) is (0.5-10) : 1.
8. A method for treating a cardiovascular disease, comprising: administering the pharmaceutical composition according to claim 1 to a subject in need thereof.
9. The method according to claim 8 , wherein the cardiovascular disease is selected from the group consisting of hypertension, heart failure, coronary heart disease, rheumatic heart disease, congenital heart disease, left ventricular dysfunction, endothelium dysfunction, diastolic dysfunction, hypertrophic cardiomyopathy, diabetic cardiomyopathy, supraventricular and ventricular arrhythmia, atrial fibrillation, cardiac fibrosis, atrial flutter, harmful vascular remodeling, myocardial infarction and its sequelae, arteries atherosclerosis, angina pectoris, primary and secondary pulmonary hypertension, and renal vascular hypertension.
10. The pharmaceutical composition according to claim 6 , wherein the compound of formula (1K) is the crystalline form I, the crystalline form II or a mixture of the crystalline form I and the crystalline form II in any ratio.
11. The pharmaceutical composition according to claim 1 , wherein a mass ratio of the at least one neutral endopeptidase inhibitor to the compound of formula (1K) is (0.5-5) : 1.
12. A method for treating a cardiovascular disease, comprising: administering the pharmaceutical kit according to claim 2 to a subject in need thereof.
13. The method according to claim 12 , wherein a mass ratio of the first pharmaceutical composition to the second pharmaceutical composition is (0.5-10):1.
