Abstract: OBJECTIVE To establish a methed for determining the concentration of kanamycin and dexamethson in DICA eye drops.METHED The concentration of kanamycin was determined by polarmetric analysis,ultravio specyro-photometry was employed for determination of dexamethson sodium phosphate.RESUITS:The average recovery of kana-mycin was 99.3%,RSD=0.40%(n=5);the average recovery of dexamethson sodium phosphate was 99.2%,RSD=0.20%(n=5).CONCLUSION It is a simple method for the quantitative analysis of compound preperation.
