Simultaneous spectrophotometric determination of formoterol fumarate and budesonide in their combined dosage form

A new UV spectrophotometric method for the simultaneous determination of formoterol fumarate and budesonide in their combined dosage form has been developed. The λ max values for formoterol fumarate and budesonide in methanol medium were found to be 217 nm and 252 nm respectively. The results of analysis by this method have been found to be precise and accurate.
