ABSTRACT

VALSARTAN is frequently associated in pharmaceutical formulations against the hypertension. The qualification presents several problems. An attempt has done that the compound in pharmaceutical tablet dosage form include the separation of excipients has been developed and validated. A rapid and sensitive UV-Visible spectroscopic method was developed for the estimation of valsartan in pure and its pharmaceutical formulations. The method was validated as per International conference on Harmonization (ICH) guidelines. The valsartan was monitored at 233 nm with UV detection. The method was linear (r2=0.999) at concentration ranging from 5 to 60ug/ml, precise (intra-day relative standard deviation (RSD) and inter-day RSD value < 1.0%), accurate (mean recovery = 100.2%), specific and robust. The results showed that the proposed method is suitable for the precise, accurate and rapid determination of valsartan in bulk, its capsule dosage form.

Keywords: Valsartan, method development, Validation, UV spectroscopy, Dosage form.
