| titleOfInvention | Water dispersible antibiotics |
| abstract | The water-dispersibility of a water-insoluble polypeptide antibiotic is increased by dissolving the antibiotic and a highly water-soluble polymeric material in a non-aqueous solvent such as methanol, ethanol, isopropanol, benzyl alcohol or pyridine and then removing the solvent, preferably by evaporation, to obtain a dry readily water-dispersible complex. The antibiotic may be tyrothricin, tyrocidine or gramicidin and the polymeric material may be a polymer or copolymer of vinyl pyrrolidone, a poly-N-vinyl oxazolidinone or a block copolymer of polyoxyethylene and polyoxypropylene.ALSO:A dry, readily water-dispersible complex of a water-insoluble polypeptide antibiotic and a highly water-soluble polymeric material is obtained by dissolving the antibiotic and the polymeric material in a non-aqueous solvent such as methanol, ethanol, isopropanol, benzyl alcohol or pyridine and then removing the solvent, preferably by evaporation.
