Study Progress in Eye Irritation Test in vivo for Ophthalmic Preparations / 中国药师

ABSTRACT

Various new ophthalmic formulations have been prepared to enhance ocular bioavailability,while lots of irritant sub-stances are applied,including surfactants,polymers and other cationic materials. Therefore,safety of the preparations has been paid more and more attention besides the efficacy. Since in vitro experiments lack of associated enzymes and integral reaction of organiza-tion,the reasonability and correlation of the results extrapolated to the animal experiments still need to be further proved. The in vivo common eye irritation methods( winking,histopathological slices,Draize score and confocal microscopy test etc)were reviewed,eval-uated and analyzed in the paper.
