More Information
Summary:Aqueous liquid preparations containing gatifloxacin (chemical name: (+/-)-1-cyclopropyl-6-fluoro-1,4-dihydro-8-methoxy-7-(3-methyl-1-piperazinyl)-4-oxo-quinolinecarboxylic acid) or its salt and sodium edetate; and a method for enhancing the corneal permeability of gatifloxacin, a method for preventing crystallization of gatifloxacin and a method for preventing coloration of gatifloxacin each by blending gatifloxacin or its salt with sodium edetate. L'invention porte sur des préparations liquides aqueuses contenant une gatifloxacine (nom chimique: acide (+/-)-1-cyclopropyl-6-fluoro-1,4-dihydro-8-méthoxy-7-(3-méthyl-1-piperazinyl)-4-oxo-quinolinecarboxylique) ou son sel et un édétate de sodium. L'invention porte également sur un procédé visant à renforcer la perméabilité cornéenne de la gatifloxacine, sur un procédé visant à prévenir la cristallisation de la gatifloxacine et sur un procédé visant à prévenir la coloration de la gatifloxacine, tout cela en mélangeant la gatifloxacine ou son sel avec l'édétate de sodium.
