A topically applicable pharmaceutical composition comprises at least one liquid lipid, at least one pharmaceutical active ingredient which is soluble in at least one of the liquid lipids and is re-absorbed by the skin, and a hydrous gel which is the main component of the composition, whereby at least one lipid and at least one active ingredient are worked into the gel and the composition is essentially free of emulsifying agents and solid constituents, with the exception of the necessary gelatinizing agent required to form the hydrous gel. All of the active ingredients are present in dissolved form, whereby at least one active ingredient is dissolved in the liquid lipid, and this lipid containing the dissolved active ingredient is itself the internal phase and is worked into the hydrous gel as the external phase. The composition is also essentially free of surface-active substances. Process for manufacturing a topically applicable pharmaceutical composition of this kind which provides for the fact that at least one active ingredient re- absorbable by the skin is dissolved, preferably in concentrated form, in a lipid and that this solution is intermingled as the internal phase in a hydrous gel as the external phase, whereby this hydrous gel is the main component in the composition. The composition obtained thereby is highly stable and has favorable galenic properties.

Une composition pharmaceutique d'application topique est constituée d'au moins un lipide liquide, d'au moins un agent actif pharmaceutique qui soit soluble dans au moins un lipide liquide et qui puisse être résorbé par la peau, ainsi que d'un gel hydraté, principal constituant de la composition. Au moins un lipide et au moins un agent actif sont incorporés au gel et la composition est sensiblement exempte d'émulsifiants et de constituants solides, à l'exception des produits de gélification nécessaires à la formation du gel hydraté. Tous les agents actifs sont utilisés sous la forme de solutés, un agent actif étant cependant dissous dans un lipide liquide, et le lipide contenant cette substance active est incorporé comme phase interne dans le gel hydraté, constituant ainsi la phase externe. La composition est également sensiblement exempte d'agents tensio-actifs. Un procédé de production d'une telle composition pharmaceutique d'application topique prévoit qu'au moins un agent actif pouvant être résorbé par la peau et, de préférence, concentré, est dissous et qu'ensuite cette solution est incorporée comme phase interne dans un hydrogel, constituant ainsi la phase externe. Cet hydrogel est le principal constituant de la composition. La composition ainsi obtenue se caractérise par une forte stabilité et des propriétés galéniques favorables.
