Abstract: A method for preparing highly stable aqueous gels based on metronidazole, well suited for treating such skin conditions as rosacea, acne and dermatitis, entails the successive steps of: (A) forming a solvent medium M comprising water and propylene glycol; (B) dissolving the metronidazole in this solvent medium M, and optionally diluting the medium obtained by addition of water, whereby a solution S of metronidazole is obtained; and thence (C) mixing the solution S obtained with a gelling polymer, in a sufficient amount to ensure gelling of the composition.

Abstract: Physically stable pharmaceutical/cosmetic compositions contain at least one hydrophilic phase, at least one lipophilic phase and at least one active principle, e.g., at least one steroidal anti-inflammatory agent, anti-fungal agent, anti-parasitic agent, nuclear receptor modulator and/or sex steroid, said at least one active principle being present in dissolved state in each of these phases; these are formulated via characteristic multi-step methodology.

Abstract: Cosmetic/dermatological compositions useful for the treatment of a variety of dermatological conditions, including keratinization disorders, acne, eczema, psoriasis, etc., comprise an invert emulsion containing at least one active agent sensitive to the presence of water, notably a derivative of vitamin D, and solubilized in a glycolic or hydroglycolic dispersed hydrophilic phase, a lipophilic continuous phase and an emulsifier having an HLB ranging from 2 to 7; these invert emulsions exhibit good stability and avoid crystallization of the active agent and/or chemical degradation thereof.

Abstract: A complex based on anthralin and a sterol, characterized in that its melting point is 10 to 25 degrees Celsius lower than that of the constituent of the complex melting at the lowest temperature and that the proportion of anthralin varies between 10 and 90 mol %.
