Assigned to Ningxia Medical University · Expires 2023-12-12 · 2y expired

What this patent protects

本发明涉及医药制剂领域，公开了一种奥拉帕利片及其制备方法。所述奥拉帕利片由奥拉帕利素片和包衣层组成，所述奥拉帕利素片由奥拉帕利固体分散体、填充剂、润滑剂和助流剂组成，所述奥拉帕利固体分散体由原料药奥拉帕利和载体材料组成。本发明药物以分子形式分散在载体材料中，降低药物溶解时所需跨越的能垒，显著增加奥拉帕利片的溶出度，解决了奥拉帕利的难溶性问题。本发明与原研药溶出度保持高度一致，且生产方法简单易行，易于工业化生产，有较大的应用价值。
