CN107635545A — 用于增强粘膜表面处活性剂的输送的低渗水凝胶制剂

Assigned to Johns Hopkins University · Expires 2018-01-26 · 8y expired

What this patent protects

已经开发出水凝胶形成聚合物，优选泊洛沙姆，的低渗制剂，用于增强治疗剂、诊断剂、预防剂或其它制剂通过粘膜至上皮组织的递送，特别是具有粘膜涂层的上皮组织。聚合物以高于、处于或小于其在等渗条件下的临界凝胶浓度(CGC)的浓度来施用。调节制剂的低渗性，使得聚合物在较低的浓度下胶凝。于其CGC施用于阴道或结肠直肠中的泊洛沙姆凝胶将在管腔中形成凝胶的“栓塞”。
