Spectrometric Determination Of Formoterol Fumarate In Rotacap Formulation

Author(s): P.N.S Pai, S.K Sandeep, A.B.P Sekhar

A new simple, sensitive spectrometric method was developed on the basis of a colour reaction of formoterol with diazotised p-nitroaniline.The method is based on formation of yellow chromophore which has an absorption maxima at 398 nm and obeys Beer's law in the concentration range of 1- 40 μg/ml. Results of the analysis were statistically validated by recovery studies. The method was found to be suitable for routine determination of formoterol fumarate in rotacap formulation.
