Abstract: The present invention provides pharmaceutical compositions and methods for dispensing the same using an aerosol whereby the composition takes the form of foam. Additionally, the present invention provides a barrier system including a concentrate separated from a non-chlorine aerosol propellant wherein the concentrate includes a non-aqueous solvent, an emulsifying agent, a thickening agent, at least one medicament and optionally an aqueous solvent.

Abstract: A method of stabilizing an aqueous dispersion of water-absorbent particles and at least one matrix-forming hydrophilic thickening agent comprises the steps of evacuating gas from said dispersion and subjecting the latter to compression by means of a relative pressure sufficient to irreversibly transform the dispersion into a stable particle-matrix system. A method of preparing a stable semi-solid preparation of dry, preferably bead-shaped water-absorbent particles comprises forming a homogenous dispersion comprising from 30 to 70% by weight of said beads, from 0.1% by weight of at least one hydrophilic thickening agent, capable of forming a matrix for said beads, and from 20 to 55% by weight of water, and stabilizing the dispersion formed as above. The water-absorbent particles may consist of cross-linked carbohydrates or polyacrylamide or derivatives thereof. The stable preparation may advantageously be packed in aerosol type containers and be used for the treatment of wounds and skin.
