Background:

Deep learning models show promise in predicting drug formulation properties, outperforming traditional machine learning.
Existing deep learning approaches struggle with imbalanced, small datasets and suboptimal neural network architectures, hindering prediction accuracy.
Predicting disintegration time for oral fast disintegrating films (OFDF) and dissolution profiles for sustained-release matrix tablets (SRMT) remains challenging.

Purpose of the Study:

To develop advanced deep learning models for accurate prediction of OFDF disintegration time and SRMT dissolution profiles.
To address performance degradation caused by small, imbalanced datasets and inefficient network structures in pharmaceutical formulation prediction.
To introduce novel methodologies, including Principal Component Analysis (PCA) and Wasserstein Generative Adversarial Networks (WGAN), for enhanced predictive modeling.

Main Methods:

For OFDF, Principal Component Analysis (PCA) was employed to reduce dataset dimensionality, aiming to improve prediction performance and decrease training duration.
For SRMT, a Wasserstein Generative Adversarial Network (WGAN) was utilized to generate synthetic data, overcoming limitations posed by scarce experimental data.
These deep learning models were specifically designed to maximize prediction accuracy for key pharmaceutical formulation parameters.

Main Results:

The proposed PCA-based method significantly improved prediction performance and reduced training time for OFDF disintegration time.
The WGAN-based approach effectively addressed the challenge of limited experimental data for SRMT, leading to improved predictive modeling.
Experimental results demonstrated that the developed deep learning models outperformed existing methods across all evaluated performance metrics.

Conclusions:

The study successfully developed novel deep learning models for pharmaceutical formulation prediction, enhancing accuracy for OFDF and SRMT.
The integration of PCA and WGAN represents a significant advancement in overcoming data limitations and improving predictive capabilities in drug formulation.
The proposed methods offer a robust and efficient approach for predicting critical drug formulation parameters, paving the way for optimized drug development.
