Abstract: A liquid pharmaceutical composition is contemplated that comprises a pharmaceutically effective amount of a drug dissolved or dispersed in an aqueous medium. The aqueous medium consists essentially of water, about 3% to about 10% w/v polyvinylpyrrolidone, about 60% to about 75% w/v of C3-C6 polyol that includes more than 55% w/v of a non-reducing disaccharide, trisaccharide or tetrasaccharide such as sucrose, optionally about 0.01% to about 0.5% w/v of a glycyrrhetic acid, glycyrrhizinate derivative or salt thereof, and one or more flavorants, and preferably includes one or more preservatives. The liquid composition is room temperature stable, and may have a pleasant taste.

Abstract: Novel stable, concentrated, biologically active and ready-to-use lipid-comprising drug delivery complexes and methods for their production are described. The biological activity of the complexes produced are comparable to the formulations prepared according to the prior art admixture method and upon purification, the complexes produced by the method of this invention are 50 to 500 fold more concentrated than the complexes formed by admixture. The method described herein provides for the large scale production of lipid-comprising drug delivery systems useful for gene therapy and other applications.
