Abstract
An object is to provide an ophthalmic aqueous preparation excellent in the retention of gatifloxacin in a tear fluid and the preparation of gatifloxacin into an aqueous humor and a conjunctiva. Another object is to prevent the formation of any precipitate and the reduction in viscosity in the aqueous liquid preparation. An aqueous liquid preparation comprising gatifloxacin, a pharmacologically acceptable salt thereof or a hydrate of gatifloxacin or the salt and at least 0.15 w/v % of xanthan gum enables to improve the retention and penetration of gatifloxacin. When at least 0.2 w/v % of sodium chloride is added to the aqueous liquid preparation, the formation of any precipitate and the reduction in viscosity in the aqueous liquid preparation can be prevented.
