Non-destructive quantitative analysis of risperidone in film-coated tablets.
A simple, non-destructive, methodology based on FT-Raman spectroscopy was developed for the quantitative analysis of risperidone in commercially available film-coated tablets. A simple linear regression model was constructed based on standard tablets, prepared using the same manufacturing process as the commercially available. The tablets contained 0.27, 0.54, 1.08, 1.62, 2.16, 3.24 and 4.32 wt% risperidone. The most prominent Raman vibration of the active pharmaceutical ingredient at 1533 cm(-1), recorded using a home-made rotating system, was plotted against concentration. The model was tested on commercial film-coated tablets. The results were compared against those obtained by application of HPLC on the same samples.
