Potassium (-)-hydroxycitric acid methods for pharmaceutical preparations for stable and controlled delivery

摘要

A method for making the potassium and sodium salts of (-)-hydroxycitric acid and mixtures thereof workable, non-hygroscopic and non-reactive in acidic media by encasement in hydrophobic and acidophobic polymers. The calcium and magnesium salts of (-)-hydroxycitric acid likewise can be rendered nonreactive in acidic media. The resulting products are suitable for tableting, encapsulation and use in other dry media for weight loss, appetite suppression, improvements in fat metabolism and postprandial lipemia and other pharmaceutical purposes. Further, the products of this invention can be made nonreactive as components of acidic liquid drink mixes and snack bars and can be used in the production of controlled release administration formats.
