Impact of Properties of Hydrated Silicon Dioxide as Core Material on the Characteristics of Drug-containing Particles Prepared by the 2-step Process Melt Granulation Technology, MALCORE

Drug-containing particles (DCPs) are frequently used as cores in the development of solid oral dosage forms. The wet layering technique, which is a typical approach for preparing DCPs, requires the use of solvents and a long manufacturing time. In our previous study, we developed a novel manufacturi...

Description
Summary:Drug-containing particles (DCPs) are frequently used as cores in the development of solid oral dosage forms. The wet layering technique, which is a typical approach for preparing DCPs, requires the use of solvents and a long manufacturing time. In our previous study, we developed a novel manufacturing technology, MALCORE ® , which can solve these problems through melt granulation. However, particle size control methods for DCPs in MALCORE ® and the effect of the physical properties of the hydrated silicon dioxide (HSD) used for the core have not been clarified. The aim of this study was to examine the effects of the particle and pore sizes of HSD on the properties of the prepared DCPs. The results showed that the DCPs prepared using MALCORE ® could be controlled by the particle size of HSD. The drug-loading efficiency tended to decrease as HSD particle size increased. Additionally, the amount of drug layering in DCPs increased as the pore size of HSD increased, but HSDs with a pore size much larger than the particle size were not able to properly layer the drug. These findings are helpful for applying MALCORE ® to a variety of oral drug formulations. Graphical Abstract
