Abstract

The invention relates to a lipidosome medical composition which uses momestasone furoate as an active component, and a cyst diameter of lipidosome is smaller than 800nm. The composition comprises 0.025 percent to 0.2 percent of momestasone furoate as the active component, 0.5 percent to 6 percent of phospholipid, 0 percent to 1 percent of lipophilic additive, 0.01 percent to 1 percent of antioxidant which is used for preserving the medical composition, a pH buffering agent which is used for retaining a pH value from 5 to 7.5, 3 percent to 15 percent of humectant, 20 percent to 30 percent of oil phrase component, 0.01 percent to 0.1 percent of antimicrobial preservative and the balanced of water. The momestasone furoate lipidosome cream is used for treating skin diseases of human beings or animals.

Description

field of invention [0001] The invention relates to a liposome preparation, in particular to a cream containing mometasone furoate liposome. Background technique [0002] Mometasone furoate (mometasone furoate, CAS: 83919-23-7), its molecular formula is as follows: [0003] [0004] The trade name of mometasone furoate cream is Elocon, which was first developed and listed by Schering Corporation in 1988. At present, there is only one specification of 0.1%, and the manual of Elocon cream (http: / / www.fda.gov / cder / pediatric / labels / Mometasone%20Cream.pdf) discloses that its main component is: mometasone furoate 0.1 %; Excipients: hexylene glycol (hexylene glycol), phosphoric acid, propylene glycol monostearate (55% monoester), stearyl alcohol, ceteareth-20 (ceteareth-20), titanium dioxide, Aluminum octenyl succinate starch, white wax, white petrolatum, purified water, but the drug also has side effects of general skin glucocorticoid preparations, such as inhibition of the HP...
