Method for applying an active ingredient to a substrate, compositions for said method, container containing a composition and use of said compositions

Preparation of a foamable dosage form comprises providing a liposome suspension containing an active agent; providing at least a foaming agent and optionally a foam former, where the foam former and foaming agent are selected with respect to the composition of the liposome suspension, such that it does not diffuse into the particles of the agglomerate phase, and the foaming agent exhibits a boiling point of greater than -25[deg] C, preferably 0[deg] C; and providing a container for absorbing the liposome suspension, foaming agent and optionally a foam former. Independent claims are included for: (1) a composition for applying an active substance on a substrate, where the active substance is dissolved in the liposome suspension containing the foaming agent and optionally a foam former, such that the substrate is foamable, and the particles of the agglomerate phase are deposited during the disintegration of the foam on the substrate; and (2) a container comprising the composition in the form of a liposome suspension. ACTIVITY : Vulnerary. MECHANISM OF ACTION : None given.
