AbstractTablet splitting is a practice disseminated among health professionals for dose adjustments, swallowing facilitation or even treatment cost reduction. Nevertheless, tablets not designed for this purpose cause imprecise dosage and stability loss with important therapeutic repercussions. Novel technologies of modified drug release tablets have come to market including new materials and innovative production processes, for example, polymeric matrix, orodispersible, 3D printing, MUPs, etc. The heterogeneity and complexity of these tablets go well beyond a traditional gastroresistant coating tablet, making orientations on the practice of tablet subdivision difficult. This editorial aims to provide a critical and up-to-date evaluation of this scenario based on the most recent studies involving the subdivision of modified-release tablets.
