چکیده    Our main objective is to develop an accurate and precise rp-hplc method for the simultaneous determination of valacyclovir hcl and ritonavir in tablet dosage form. an agilent tc-c18 (2) column is used for the separation of drugs by a mobile phase consisting of methanol,acetonitrile and water mixture in the ratio of 35:41.5:23.5v/v. the flow rate maintained was 1.3 ml/min and the wavelength used for detection was 222 nm. the linearity was observed in the range of 12.5-125μg/ml for valacyclovir hcl (vc) and ritonavir (rt) with a correlation coefficient of 0.9987 and 0.9981 respectively. the mean percentage recoveries for 80%,100% and 120% accuracy were found to be 101.7%±2.09,100%±2.49 and 101.5%±1.61 respectively for vc. the mean percentage recoveries for 80%,100% and 120% accuracy were found to be 104.3%±0.99,100%±1.77and 99.0%±1.22 respectively for rt. linearity,accuracy,precision and robustness parameters for the suggested method were estimated for validation. the developed method can be utilized in the analysis of vc and rt tablets. © 2015 penerbit utm press. all rights reserved.
