Embodiment 1

[0043] prescription:

[0044]

[0045]

[0046] Preparation process: Take 90% of the prescribed amount of water for injection, add the main drug and osmotic pressure regulator in the prescribed amount, stir for 20 minutes, adjust the pH value to 3.5-4.5 with a pH regulator, add water to the full amount, pass the liquid medicine through a 0.45 μm coarse Filter, 0.22μm fine filter. Then the filtered medicinal solution is divided into 2-5ml plastic ampoules by BFS, sterilized by high pressure steam at 121 degrees centigrade for 15 minutes, inspected by light and packaged to obtain the salbutamol sulfate atomized inhalation solution preparation.

Embodiment 2

[0048] prescription:

[0049]

[0050] Preparation process: Take 90% of the prescribed amount of water for injection, add the main drug and osmotic pressure regulator in the prescribed amount, stir for 20 minutes, adjust the pH value to 3.5-4.5 with a pH regulator, add water to the full amount, pass the liquid medicine through a 0.45 μm coarse Filter, 0.22μm fine filter. Then the filtered medicinal solution is subpackaged into 2-5ml plastic ampoules by BFS, sterilized by high pressure steam at 115 degrees centigrade for 30 minutes, inspected by light and packaged to obtain the salbutamol sulfate atomized inhalation solution preparation.

Embodiment 3

[0052] prescription:

[0053]

[0054]

[0055] Preparation process: Take 90% of the prescribed amount of water for injection, add the main drug and osmotic pressure regulator in the prescribed amount, stir for 20 minutes, adjust the pH value to 3.5-4.5 with a pH regulator, add water to the full amount, pass the liquid medicine through a 0.45 μm coarse Filter, twice 0.22μm fine filter. Then the filtered medicinal solution is divided into 2-5ml plastic ampoules by BFS, inspected by light and packaged to obtain the salbutamol sulfate atomized inhalation solution preparation.

Abstract

The invention discloses a salbutamol sulfate aerosol inhalation solution, and a preparation process and application thereof. The salbutamol sulfate solution is prepared from the following components:salbutamol sulfate, an osmotic pressure regulator, a pH regulator and water for injection, wherein the pH value of the salbutamol sulfate solution is 3.0 to 5.0. The salbutamol sulfate solution has good atomization performance and thermal stability.

Description

technical field [0001] The invention relates to a salbutamol sulfate atomized inhalation solution and a preparation process and application thereof. Background technique [0002] Asthma and chronic obstructive pulmonary disease (COPD) have become the two most common respiratory diseases worldwide. According to the WHO forecast, by 2025, the number of asthma patients in the world will increase to 400 million. In terms of chronic pulmonary obstructive COPD, according to the important paper "China Lung Health [CPH] Research: A National Cross-sectional Study" by Academician Wang Chen, the prevalence of COPD in adults aged 20 and over in my country is 8.6%, and it reaches 8.6% for adults over 40 years old. 13.7%, the prevalence rate of people over 60 years old has exceeded 27%, and the total number of patients in the country is 99.9 million. COPD has become the most common chronic disease on a par with hypertension and diabetes, constituting a major disease burden in my country. ...
