This invention provides a method of augmenting an epithelial mucosal barrier, by contacting the barrier with a topical composition. This invention also provides the topical composition.
The topical composition comprises, dispersed or dissolved in a topically acceptable vehicle, at least one polymer containing either a repeat unit of structure 1 or a repeat unit of structure 2, or a mixture
This method and composition are useful in improving mucosal barrier function by, for example, topical application to an exposed or injured epithelial surface or by coating a compromised mucosal barrier in, for example, inflammatory bowel disease.
这项发明提供了一种通过将一种局部组合物与屏障接触来增强上皮粘膜屏障的方法。这项发明还提供了该局部组合物。该局部组合物包括至少一种
聚合物,该
聚合物包含结构1的
重复单元或结构2的
重复单元,或二者的混合物,分散或溶解在局部可接受的载体中。该方法和组合物可用于通过将其局部应用于暴露或受伤的上皮表面,或通过在受损的粘膜屏障上涂覆,例如在炎症性肠病中,改善粘膜屏障功能。
