摘要： Water soluble complexes of normally water insoluble drugs such as chlorothiazide, aminobenzoic acid, furosemide and mixtures thereof wherein the complexing agent is a polyvinyl lactam such as polyvinylpyrrolidone, polyvinylpyrrolidone-halogen complex or mixtures thereof. The invention also relates to the preparation of these complexes which involves dissolving the reactive components in an aqueous inert solvent combining the complexing agent and drug in a weight ratio of from about 1:1 to about 10:1 with agitation for a period of at least 5 minutes at a temperature above 3 DEG C and below the boiling point of the aqueous solvent solution under a pressure up to about 50 psig.
