EYE DROPS AND METHOD FOR THEIR OBTAINING Russian patent published in 2005 - IPC

FIELD: pharmaceutics.

SUBSTANCE: the present innovation deals with medicinal preparations designed as solution and indicated for therapeutic needs. Eye drops contain ciprofloxacin hydrochloride monohydrate being equivalent to 0.3% free foundation, a buffer system that keeps pH within 3.5-5.5 interval, as a conserving agent - benzalconium chloride and a s a stabilizer - the salt of disodium ethylenediamine tetraacetic acid, moreover, their range of osmolality values correspond to 150-450 mM/kg H₂O. Eye drops should be obtained by preparing buffer system in which mannitol should be dissolved followed by the salt of disodium ethylenediamine tetraacetic acid, benzalconium chloride, ciprofloxacin hydrochloride. Then one should perform the control for the quality of obtained solution to be then filtered by applying sterilizing elements and packed. This innovation provides treatment of eyes at creating the pressure in an eye and at certain desired osmolality.

EFFECT: higher efficiency of therapy.
