OBJECTIVE:To develop the gel of norfloxacin.METHODS:The gel of norfloxacin was made mainly of CMC Na,besides norfloxacin.The content was determined by UV spectrophotometry at 273 nm,the standarol curve of niterendipine showed good linearity in the concentration range of 2.0 ~ 8.0 μg·ml -1 , r = 0.999 96 .RESULTS:In the test of content,the average rate of recovery was 100.46% and RSD = 1.93% ( n =5).The gel staying was natural temperature,no changes had been found.This medicine had great effect in the clinic of 30 cases.CONCLUSIONS:This medicine is easily produced.The quality of the gel is able to be controlled and the stability kept.It is a useful medicine for the clinic.
