Determination of ciprofloxacin hydrochloride capsules in FTIR

OBJECTIVE To establish a method for determination of ciprofloxacin hydrochloride in the capsules. METHODS Diffuse reflectance in FTIR was used to determine ciprofloxacin hydrochloride in capsules. RESULTS Relationship between absorbance and concentration was linear. The average recovery of ciprofloxacin hydrochloride was 98.30%,and RSD was 2.31%. CONCLUSIONS This method is simple,accurate and reliable.
