Abstract:
The RP-HPLC method was developed and validated for simultaneous estimation
of Cefuroxime and Clavulanic acid bulk and its Tablet dosage form. The RPHPLC
method has shown adequate separation of Cefuroxime and Clavulanic acid
in bulk and its formulation. The separation was achieved on a BDS hypersil C18,
(250mm X 4.6mm i.d., 5μm particle size) using ACN: Potassium dihydrogen
phosphate buffer (75:25 v/v) as mobile phase. The mobile phase at a flow rate of
1.0 ml/min, Injection volume 20μl and wavelength of detection used was 217 nm.
The retention time for Cefuroxime and Clavulanic acid was obtained as 3.060
min and 7.683 min, respectively. The linearity of the proposed method was
investigated in the range of 12.5-37.5 μg/ml and 6.25-18.75 μg/ml for
Cefuroxime and Clavulanic acid, respectively. Regression coefficient for
Cefuroxime and Clavulanic acid was obtained as 0.9991 and 0.998,
respectively.The developed method was validated as per ICH guideline, for its
accuracy, precision, LOD & LOQ, Robustness,specificity and the results were found to be satisfactory, thus the method is accurate, precise , rapid and simple
for estimation of Cefuroxime and Clavulanic acid. Key words:Cefuroxime,
