ABSTRACT
The main object of analytical chemistry is to develop scientifically substantiated methods that allow the qualitative
and quantitative evaluation of materials with certain accuracy. A rapid, simple and precise HPLC method was
developed for simultaneous estimation of two drugs Nebivolol and S – Amlodipine from pharmaceutical dosage
forms. The estimation was carried out using Sunfire C18 (4.6×250mm, 5μ) column; mobile phase consisting of
Acetonitrile: Water (40:60 v/v); the flow rate of 0.9mL/min and ultraviolet detection at 220nm. Both the drugs
were properly resolved having runtime of 6 min. the method was validated as a final verification of method
development with respect to Precision, Linearity, Accuracy, Ruggedness and Robustness. The validated method
was successfully applied to the commercially available pharmaceutical dosage forms, yielding very good and
reproducible results.
Keywords: Nebivolol, S – Amlodipine, HPLC, Method development and Validation.
