| titleOfInvention | Inhalation type aerosol, raw material composition and preparation method thereof |
| abstract | The invention discloses a suction type aerosol, a raw material composition and a preparation method thereof. The invention discloses a raw material composition of an inhalation aerosol, which comprises a pharmaceutical active ingredient and a propellant, wherein the pharmaceutical active ingredient comprises a long-acting beta receptor agonist and glucocorticoid; the propellant comprises tetrafluoroethane. The invention discloses an inhalation aerosol, which comprises the raw material composition, a pressure-resistant container and a valve system. The inhalation aerosol adopts tetrafluoroethane as a propellant, and the pharmaceutical particles are prepared by adopting a supercritical method and a spray drying method during preparation, so that the inhalation aerosol with uniformly distributed particles can be obtained, and the loss in the preparation method is low; in addition, the inhalation aerosol provided by the invention adjusts the single dose spraying amount of the medicine, and effectively reduces the greenhouse effect gas dosage of the product. |
