Examples
Embodiment 1
[0035] Mometasone furoate powder 2g, Tween-8045g, polyethylene glycol caprylic / capric glyceride (Labrasol) 45g, hydroxypropyl methylcellulose 3g, simethicone 15g (viscosity 100 centistokes), pH6 .5 phosphate buffer 1g, butane 50g,
[0036] EDTA-2Na 0.1g, ethylparaben 1g, purified water to 1000ml
[0037] The preparation method is to dissolve the prescribed amount of active ingredients and hydroxypropyl methylcellulose in 600ml of purified water, sonicate or stir to form a main suspension, and add the prescribed amount of polyethylene glycol-caprylic acid / capric glycerin while stirring Esters, Tween-80, simethicone, and pH buffers were thoroughly stirred or sonicated until a uniform emulsion was formed.
[0038] The above emulsion is mixed with the prescribed amount of butane propellant, sealed and filled into an aerosol aluminum can, and sealed with a quantitative valve system. Each press contains mometasone furoate 2mg.
