Study on Formulation Quality Forecast of Sustained Release Preparation Based on BP Neural Network / 世界科学技术-中医药现代化

Optimization on sustained release preparation formulation is a multi-factor, multi-level complex optimiza-tion problem. Artificial neural network is very suitable for dealing with such complex multivariable nonlinear system. Based on analyzing the characteristics of sustained release preparation and the main influential factors of its quality, this paper focused on building a quality forecast model for sustained release preparation formulation by using BP neural network. The results showed that the BP neural network can effectively forecast the quality of sustained re-lease preparation formulation. It is a powerful optimization tool of sustained release preparation formulation.
