摘要：

We evaluated the effects of polyacrylic acid (PAA) molecular weight and crosslinking agent (beta-cyclodextrin) concentration on swelling and drug (metoclopramide) release characteristics of PAA hydrogels. Both factors, and the interactions between them, were found to have significant effects on both hydrogel swelling and drug release. In particular, increased beta-cyclodextrin concentrations led to reduced swelling and reduced drug release efficiency.
