Embodiment 1

[0021] Embodiment 1 pharmaceutical composition common tablet of the present invention

[0022]

[0023] Preparation process: Weigh the prescription amount of isosorbide mononitrate, ivabradine, starch and dextrin and mix evenly. In addition, add an appropriate amount of 50% ethanol to the mixed powder, mix evenly, make soft material, pass through a 18-mesh nylon sieve to make wet granules, and dry at about 60°C. The moisture content of the dry granules should be controlled below 1.5%. Sieve through a 20-mesh sieve, mix with magnesium stearate, and press into tablets.

Embodiment 2

[0024] Embodiment 2 pharmaceutical composition capsule of the present invention

[0025]

[0026]

[0027] Preparation process: crush isosorbide mononitrate, ivabradine, microcrystalline cellulose, and micropowder silica gel through a 100-mesh sieve, mix well, and directly fill capsules.

Embodiment 3

[0028] Embodiment 3 pharmaceutical composition bilayer tablet of the present invention

[0029]

[0030] Preparation process of isosorbide mononitrate granules: Isosorbide mononitrate is passed through a 100-mesh sieve, mannitol, lactose, and microcrystalline cellulose are passed through a 80-mesh sieve, and the prescribed amount of isosorbide mononitrate and mannitol, lactose, and microcrystalline cellulose are weighed. The crystalline cellulose is mixed evenly, and an appropriate amount of 95% ethanol solution of 6% PVP is added to granulate, dried at 60° C., and the dry granules are sieved with a 16-mesh sieve, and the prescribed amount of magnesium stearate is added to the dry granules.

[0031]

[0032] Preparation process of ivabradine granules: pass through 100 sieves for ivabradine, pass through 80 mesh sieves for pregelatinized starch and mannitol, weigh the prescribed amount of ivabradine, pregelatinized starch and mannitol and mix evenly, add 6 The 95% ethanol s...

Abstract

The invention belongs to the field of medicine and particularly relates to an application of a pharmaceutical composition taking isosorbide mononitrate and ivabradine as active pharmaceutical ingredients in preparation of medicine for treating diastolic heart failure. By conformation through a lot of pharmacology experiment, the isosorbide mononitrate and the ivabradine can obviously improving heart diastolic function of patients with diastolic heart failure, and remarkable synergistic effect is achieved in the aspect of treating the diastolic heart failure. The pharmaceutical composition is obvious in treating effect and little in side effects in treating the diastolic heart failure, and is quite good in medical application prospect.

Description

technical field [0001] The invention belongs to the field of medicine, and relates to a new application of a composition comprising isosorbide mononitrate and ivabradine, in particular to the preparation of a composition comprising isosorbide mononitrate and ivabradine for the treatment of diastolic cardiomyopathy Use in depletion medicines. Background technique [0002] The traditional concept of heart failure is that the systolic function of the heart is reduced, and the venous return blood cannot be effectively discharged, resulting in venous system congestion and peripheral tissue ischemia. The separation of diastolic heart failure (diastolic heart failure, DHF) from the traditional concept of heart failure is a great progress in heart failure research in the past 20 years. The concept of diastolic heart failure was first proposed by Kessle in 1988 to describe a clinical syndrome characterized by abnormal diastolic function with symptoms and signs of heart failure and n...
