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.
