This study introduces a novel method combining Raman spectroscopy with an Improved Snake Optimization-Convolutional Neural Network (ISO-CNN) algorithm for precise antiepileptic drug concentration measurement. The ISO-CNN model demonstrated high accuracy in predicting drug levels, offering a promising tool for pharmaceutical analysis.
Area of Science:
- Analytical Chemistry
- Spectroscopy
- Machine Learning
Background:
- Accurate measurement of antiepileptic drug concentrations is crucial for therapeutic efficacy.
- Raman spectroscopy offers non-destructive, rapid analysis of pharmaceutical compounds.
- Existing methods for spectral data analysis may require complex pre-processing or lack precision.
Purpose of the Study:
- To develop and evaluate a novel method for measuring mixed antiepileptic drug concentrations using Raman spectroscopy.
- To investigate the performance of an Improved Snake Optimization-Convolutional Neural Network (ISO-CNN) algorithm for spectral data analysis.
- To compare the proposed ISO-CNN algorithm with other optimization algorithms for drug concentration prediction.
Main Methods:
- Utilized Raman spectroscopy to measure 360 mixtures of oxcarbazepine, carbamazepine, and lamotrigine.
- Developed and applied an Improved Snake Optimization (ISO) algorithm integrated with a Convolutional Neural Network (CNN) for spectral data analysis.
- Pre-processed raw spectral data and trained/evaluated the ISO-CNN model.
Main Results:
- The ISO-CNN algorithm achieved excellent performance in predicting oxcarbazepine concentration, with high determination coefficients (R²) of 0.99378 for validation and 0.99627 for testing.
- The root mean square errors (RMSE) for oxcarbazepine prediction were low (0.0295 for validation, 0.0278 for testing), indicating high precision.
- Comparative analysis showed the superiority of the ISO-CNN algorithm over other tested optimization algorithms.
Conclusions:
- Raman spectroscopy combined with the ISO-CNN machine learning algorithm provides a powerful and accurate approach for predicting antiepileptic drug concentrations.
- The developed method demonstrates potential for routine pharmaceutical analysis and therapeutic drug monitoring.
- The improved optimization strategy of the ISO algorithm enhances the speed and accuracy of spectral data analysis.
