Abstract
Water soluble, powder form compositions suitable for completely and rapidly dissolving active ingredients which usually only dissolve in water in the presence of base salts, such as antibiotics of the betalactamide family, for example penicillins and their derivatives, cephalosporins and their derivatives, or other active ingredients such as sulphamides and quinolones, for oral absorption thereof and their applications. The water soluble powder form compositions contain, in combination and in powder form, at least one water soluble active ingredient, not in salt form, and with an exclusively alkaline pH, an excess of one or more strong base salts, and one or more buffers comprising one or more substances and capable of maintaining the pH of the medium at a level below the normal solubilization pH of said active ingredient. Aqueous solution compositions obtained from said powder form compositions are also described.
