Determination of Tirofiban Hydrochloride/Sodium Chloride Injection by UV Spectrophotometry / 中国药房

OBJECTIVE:To develop a method for the determination of tirofiban in Tirofiban hydrochloride/sodium chloride injection.METHODS:Tirofiban was determined by UV spectrophotometry at a wavelength of 225 nm.RESULTS:The linear range of tirofiban was 30～70 ?g?mL-1(r=0.999 7) and its average recovery was 100.04% (RSD=0.23%).CONCLUSION:The method is simple,accurate and reliable for content determination of Tirofiban hydrochloride/sodium chloride injection.
