A user-friendly application for predicting the outcome of co-crystallizations

Abstract

An automated application, CoForm, was used for predicting the outcomes of attempted co-crystallizations between two active pharmaceutical ingredients, loratadine and desloratadine, and 41 potential co-formers from the general interest (OGI) list. The predictive abilities of the app were compared to structure-informatics tools based on hydrogen-bond propensity (HBP) and molecular complementarity (MC). The results indicate that CoForm delivered a success rate of 78% for both loratadine and desloratadine compared to 76% and 54%, respectively (HBP), and 39% and 22%, respectively (MC).
