  • Publication number: 20220184106
    Abstract: A freeze-dried formulation and a preparation method and an application thereof are provided. Triterpenoid saponin has a mass percentage of 0.004-95% in the freeze-dried formulation, a binding agent has a mass percentage of 0.01-99% in the freeze-dried formulation; the freeze-dried formulation is freeze-dried by a primary prepared solution containing the triterpenoid saponin and the binding agent; when the triterpenoid saponin has a mass percentage of 0.001%-50% in the primary prepared solution, the binding agent has a mass percentage of 0.01%-50% in the primary prepared solution, and a mass of the triterpenoid saponin increases with an increase of a mass of the binding agent; and when the triterpenoid saponin has a mass percentage of 50%-95% in the primary prepared solution, the binding agent has a mass percentage of 0.01%-20% in the primary prepared solution, and the mass of triterpenoid saponin decreases with the increase of the mass of the binding agent.

  • Patent number: 7815935
    Abstract: An orally disintegrating formulation and its preparation are provided. The orally disintegrating formulation comprises an effective amount of a pharmaceutically active ingredient and a matrix, wherein the matrix contains an amino acid and pullulan. The orally disintegrating formulation can disintegrate rapidly in oral cavity and be taken without aid of water; Moreover, the formulation has a low hygroscopicity, so that the requirements for storing or producing the formulation is decreased, and the storage life is elongated to facilitate the administration by a patient and the preparation of the protein and vaccine drugs.
