Traditional tablets are not an ideal dosage form. Many groups of patients, e.g. pediatric or geriatric, experience problems with swallowing or simply are not willing to take tablets, consequently reducing patient’s compliance. Therefore, to overcome these inconveniences, orally disintegrating tablets (OTDs) were introduced into the drug market. One of the methods of preparing ODTs is a direct compression, which is cost-efficient and simple. However, many factors are affecting the disintegration time of ODTs, which are usually optimized in a laboratory during the try-and-error assays.

We curated and greatly enhanced the database presented by Han et al. [1]. Moreover, we introduced chemical descriptors as active pharmaceutical ingredient (API) characteristics. We used H2O AutoML platform [2, 3] in order to develop a model and SHAP method to explain its predictions [4].

Based on the obtained DeepLearning model with NRMSE of 8.1% and R2 of 0.84, we have identified critical parameters affecting the process of disintegration of directly compressed ODTs.
