  • Publication number: 20240033223
    Abstract: The present disclosure relates to a fosphenytoin sodium solid composition, a lyophilization method of fosphenytoin sodium, and use of the fosphenytoin sodium solid composition. The fosphenytoin sodium solid composition comprises fosphenytoin sodium and at least one carbohydrate. The fosphenytoin sodium solid composition prepared in the present disclosure is stable and can be stored at room temperature. In addition, the lyophilization method for the fosphenytoin sodium is short in lyophilization time, the product obtained by the present method does not collapse, the reconstitution time is short, and the moisture content satisfies the quality requirements. The fosphenytoin sodium solid composition can be used for treatment of epilepsy or other convulsion states.

  • Publication number: 20230034964
    Abstract: Formulations containing pH-sensitive nanoparticles for the enteric delivery of therapeutic agents are provided. The nanoparticles include a pH-sensitive polymer that protects the therapeutic agent against degradation in the stomach and allows it to be released in the small intestine or colon. The nanoparticle formulation is particularly effective at protecting sensitive biotherapeutic agents from degradation when administered orally, and makes it possible to avoid administration of such agents by injection. Also provided are methods for producing the formulations, as well as methods of treating diseases employing the formulations.
