Assigned to Chengdu Tongdaohuiyi Biomedical Technology Co ltd · Expires 2023-09-19 · 3y expired

What this patent protects

本发明公开了布立西坦药剂、其制备方法和应用，涉及制药技术领域。布立西坦药剂包括速释相和缓释相，速释相和缓释相中布立西坦含量的质量比为1:3‑9，速释相和缓释相维氏硬度比为2.5‑8.0:1。本发明提出的布立西坦药剂利用速释相能够迅速释药达到最低有效血药浓度缓解癫痫持续状态，缓释相缓慢释放余下活性药物，维持稳态血药浓度衰减不良反应。对于诸如老人、儿童等吞咽困难患者，该药剂可置于适宜载体如牛奶、果汁中分散后服用，提高患者的服药依从性且维持缓释效果不变。
