Embodiment 1

[0031] Example 1: Preparation of nasturtium extract powder spray by adding sugar carrier method

[0032] 3.25g nasturtium extract, 0.5g HPMC, 1.25g lactose were dissolved in 50% ethanol, stirred overnight to make it into a clear solution. Turn on the spray dryer and adjust the spray drying parameters as follows: the drying temperature is 78°C, the circulation pump power is 100%, the feed rate is 25%, and the atomizing air flow rate is 500L·H -1 , The atomizing air pressure is 0.6MPa. The above solution is placed at the spray drying inlet for spray drying. After the drying process, the obtained micropowder was collected and transferred to a vacuum drying oven, and dried at 40° C. for 24 hours. Take dry micropowder, load in 3 # Available in HPMC capsules.

Embodiment 2

[0033] Example 2: Preparation of Trollus chinensis extract powder spray by adding sugar carrier method

[0034] 3.25g nasturtium extract, 1.75g ​​HPMC, were dissolved in 50% ethanol, stirred overnight to make it into a clear solution. Turn on the spray dryer and adjust the spray drying parameters as follows: the drying temperature is 78°C, the circulation pump power is 100%, the feed rate is 25%, and the atomizing air flow rate is 500L·H -1 , The atomizing air pressure is 0.6MPa. The above solution is placed at the spray drying inlet for spray drying. After the drying process, the obtained micropowder was collected and transferred to a vacuum drying oven, and dried at 40° C. for 24 hours. Take the commercial lactose monohydrate, grind it through a 200-mesh sieve, collect the obtained lactose powder, put it in a three-dimensional mixer with the above-mentioned dry powder, and mix it at 100r·min -1 Mixed for 30min, loaded at 3# Available in HPMC capsules.

Embodiment 3

[0035] Embodiment 3: Preparation of nasturtium extract powder mist without adding sugar carrier method

[0036] 3.25g nasturtium extract, 1.25g HPMC, 0.5g ammonium carbonate were dissolved in 50% ethanol, stirred overnight to make it into a clear solution. Turn on the spray dryer and adjust the spray drying parameters as follows: the drying temperature is 78°C, the circulation pump power is 100%, the feed rate is 25%, and the atomizing air flow rate is 500L·H -1 , The atomizing air pressure is 0.6MPa. The above solution is placed at the spray drying inlet for spray drying. After the drying process, the obtained micropowder was collected and transferred to a vacuum drying oven, and dried at 40° C. for 24 hours. Take dry powder, load in 3 # Available in HPMC capsules.

Abstract

The invention discloses a Chinese globeflower flower extractive dry powder inhalant for treating respiratory tract infections and inflammations and a preparation method thereof. The dry powder inhalant comprises a Chinese globeflower flower extractive, high-polymer material chitosan (CS), hydroxy propyl methyl cellulose (HPMC), povidone (PVP), polyethylene glycol (PEG) and / or gelatin, ammonium carbonate as an inorganic hole-forming agent and a saccharide carrier. The dry powder inhalant is prepared by adopting the following steps of: preparing a medicament or mixture micro powder of the medicament and an excipient with a spray drying method, and then mixing the medicament or the mixture micro powder with the corresponding saccharide carrier, wherein the particle size of the micro powder is less than 100 micrometers, the size of a majority of particles is 1-20 micrometers, the evacuation rate of a capsule is greater than 90%, and when the deposition rate of an active position is determined by a two-stage glass collider, the second-stage deposition rate is greater than 15%, and a releasing time is continued for 2 hours, 12 hours or 24 hours. The dry powder inhalant is used for treating the respiratory tract infections and inflammations, can improve local medicament concentration and relative bioavailability as well as a treatment effect and the compliances of patients.
