    • 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 solubilisation pH of said active ingredient. Aqueous solution compositions obtained from said powder form compositions are also described.
    • 适用于完全和快速溶解通常仅在碱盐存在下溶解于水中的活性成分的水溶性粉末形式组合物,例如β-乳酸酰胺家族的抗生素,例如青霉素及其衍生物,头孢菌素及其衍生物或其它活性成分 成分如硫胺和喹诺酮,用于口服吸收及其应用。 水溶性粉末形式组合物组合含有粉末形式的至少一种水溶性活性成分,不是盐形式,并且具有纯碱性pH,过量的一种或多种强碱盐和一种或多种缓冲液 包含一种或多种物质并且能够将培养基的pH保持在低于所述活性成分的正常增溶pH的水平。 还描述了由所述粉末形式组合物获得的水溶液组合物。
