  • Publication number: 20230255891
    Abstract: The present invention relates to solid dispersions including, but not limited to, co-processed carbohydrates with different solubilities and concentrations, which have a microcrystalline plate structure. The solid dispersions, excipient systems and formulations of the present invention are highly compactable and durable and when compressed into solid dosage forms demonstrate uniform densification, low friability at low pressures, and and/or relatively constant low disintegration times at various hardnesses. The solid dosage forms of the present invention demonstrate superior organoleptics, disintegration, and/or robustness.
