DEVELOPMENT AND VALIDATION OF A UV SPECTROSCOPIC METHOD FOR OLANZAPINE ANALYSIS IN PHARMACEUTICAL DOSAGE FORMS – A MULTIVARIATE CALIBRATION APPROACH Authors: Mythreyan T , SEETHARAMAN R* AND MANIKANDAN K
ABSTRACT
The objective of the current study is to establish a multilinear regression procedure wholly
precise, straightforward, sensitive, and legitimate for the assessment of Olanzapine in
commercial tablet dose forms. The multivariate calibration approach was put into effect
through generating equations through linear regression analysis, exploiting the correlated
relationship amongst absorbance as well as concentration at five unique wavelengths each of
which were meticulously selected. The maximum wavelength of olanzapine turned out to be
the value of 226 nm. The outcomes were analysed through statistical analysis. A trend towards
linearity emerged throughout the concentration range of 7-13 ?g mL-1, with acceptable
regression coefficient. The relative standard deviation scores for intra-day and inter-day
precision have been established to be 0.42 and 0.39, as well. The assay was performed and
resulted in an assortment between 99.20 % to 99.80 % w/w.
