Comparative Analysis of Sibutramine Concentration Determination

Gravimetric Methods vs. FTIR RMSE Technique in Pharmaceutical Compositions

Abstract

This paper underscores the practical implications of employing FTIR RMSE analysis in pharmaceutical research. It highlights the method's rapid and non-destructive nature for quantifying drug concentration in complex formulations, emphasizing its significance in pharmaceutical quality assurance. The study advocates for integrating FTIR RMSE with conventional gravimetric and volumetric methods to enhance the analytical toolkit for pharmaceutical compound analysis. Furthermore, it elucidates the potential of FTIR RMSE in expediting analytical processes and improving estimation accuracy. The paper accentuates the synergy between classical gravimetric techniques and modern spectroscopic methods, providing valuable insights into pharmaceutical compound analysis within heterogeneous formulations. In terms of contributions, this paper advances analytical methods in pharmaceutical research by comprehensively exploring traditional gravimetric/volumetric techniques alongside Fourier Transform Infrared Spectroscopy (FTIR) coupled with Root Mean Square Error (RMSE) analysis. It assesses their effectiveness in determining drug concentrations, mainly focusing on sibutramine quantification, a complex active pharmaceutical ingredient. The results indicate a strong correlation (R² = 0.987) between the two methodologies, with FTIR RMSE consistently yielding slightly higher results due to its sensitivity to molecular structural fluctuations and component interactions. In conclusion, this study advocates for integrating FTIR RMSE into pharmaceutical research practices. It emphasizes the need for calibration and refinement of this technique to further enhance estimation accuracy and analytical precision. It underscores the pivotal role of advanced analytical methods in various applications, including pharmaceutical and biomedical fields.
