A simple, sensitive and reproducible spectrophotometric method is developed for the determination of Atorvastatin calcium in bulk and in pharmaceutical formulations. This Method is based on the reaction of Atorvastatin calcium with Fe (III) of ferric chloride and Conc. hydrochloric acid to produce a yellow orange colored chromogen (λmax at 400 nm). Results of analysis were validated statistically and by recovery studies. This method is successfully employed for the determination of Atorvastatin calcium in various pharmaceutical preparations. https://www.biotech-asia.org/vol4no2/spectrophotometric-method-for-the-determination-of-atorvastatin-calcium-in-pharmaceutical-formulations-2/ Atorvastatin calcium; Visible Spectrophotometric determination; Beer’s Law
