Study on the method of dissolution test of norfloxacin Capsule

  • 208th Hospital, Changchun 130062

  • Received Date: 1999-03-10
  • OBJECTIVE To study the condition and method using UV-spectrophotomery for determining the concentration and dissolution of Norfloxacin capsule.METHODS The concentration of Norfloxacin capsule was detected by UV-spectrophotometry and the dissolution was detected by rotation basket method.RESULTS The iggest absorbtion was at 273nm wavelength(5μg/ml,0.4% NaOH solution).The average absorption coefficient(E1cm1%)is 1095,And the linear relationship was good(r=0 9998)In 20minutes,the dissolution rates were 80%.CONCLUSION The concentration of Norfloxacin can be detected by UV-spectrophotometry,it′s convient and rapid.It can also be wsed to detect the dvssolution of Norfloxacin capsule.
