Abstract

Oppfinnelsen gir en prosess for fremstilling av en farmasøytisk sammensetning som innbefatter en vanndispersjon av gassholdige vesikler med membraner som inneholder et amfifilt membrandannende materiale, den nevnte prosessen innbefatter å: (i) danne en væskedispersjon av gassholdige vesikler utfra en blanding som inneholder et amfifilt membrandannende materiale, (ii) lyofilisere en væskedispersjon av de nevnte gassholdige vesiklene, (iii) rekonstituere det lyofiliserte produktet fra trinn (ii) med en steril vandig væske for å danne en vanndispersjon av de gassholdige vesiklene og (iv) behandle det vandige dispersjonsproduktet fra trinn (iii) eller det lyofiliserte produktet fra trinn (ii) for å danne en stort sett aggregatfri steril vanndispersjon av gassholdige vesikler.
