  • Development of a multiparticulate drug delivery system for in situ amorphisation.: This study explores the creation of a multiparticulate drug delivery system using sodium dihydrogen phosphate to induce in situ amorphisation, enhancing the bioavailability of poorly water-soluble drugs (Holm et al., 2022).
