The administration of parenteral medicines was always being an unacceptable route in long-term treatment related to patient desires. The ultimate goal of the current study was to rectify patient discomfort by developing an oral and mechanically strong polymer PF127 based hydrogels with controlled drug-delivery to treat Type 2—Diabetes Mellitus for an extended time-period. Vildagliptin (Anti-Diabetic drug) was effectively loaded into all PMA-hydrogel discs by diffusion mechanism. The method free-radical polymerization was adopted to synthesize these PMA hydrogels by cross-linking PF127 with monomer MAA (methacrylic acid) in presence of cross-linker MBA (N, N-methylene bisacrylamide) and APS (ammonium persulfate) initiator. FTIR, DSC, XRD, TGA and SEM were conducted for developed PMA hydrogels. Surface morphology exhibited cracked porous pattern by SEM. In-vitro studies performed on both 1.2 (acidic) and 6.8 (basic) pH. Better swelling, greater drug-loading and maximum release at 6.8 pH was achieved, confirming water imbibing and pH responsiveness behavior of PMA hydrogels. FTIR study revealed absolutely no interaction amongst reaction-contents. Release kinetics confirmed non-fickian diffusion (anomalous) release as first-order, Higuchi and Korsmeyer-Peppas seemed best fitted kinetic models. Study concludes highly stable, porous, pH responsive PMA hydrogel composites were designed with controlled release effect.

在与患者意愿相关的长期治疗中，肠胃外药物的给药一直是不可接受的途径。当前研究的最终目标是通过开发一种口服和机械强度高的聚合物 PF127 基水凝胶来纠正患者的不适，该水凝胶具有受控的药物递送，以在更长的时间内治疗 2 型糖尿病。Vildagliptin（抗糖尿病药物）通过扩散机制有效地加载到所有 PMA-水凝胶盘中。在交联剂MBA（N，N-亚甲基双丙烯酰胺）和APS（过硫酸铵）引发剂的存在下，通过将PF127与单体MAA（甲基丙烯酸）交联，采用自由基聚合的方法合成这些PMA水凝胶。对开发的 PMA 水凝胶进行了 FTIR、DSC、XRD、TGA 和 SEM。表面形貌通过扫描电镜显示有裂纹的多孔图案。对 1.2（酸性）和 6.8（碱性）pH 值进行体外研究。在 6.8 pH 值下实现了更好的溶胀、更大的载药量和最大释放，证实了 PMA 水凝胶的吸水和 pH 响应行为。FTIR 研究显示反应内容之间绝对没有相互作用。释放动力学证实非菲克扩散（异常）释放为一级，Higuchi 和 Korsmeyer-Peppas 似乎是最适合的动力学模型。研究得出结论，高度稳定、多孔、pH 响应的 PMA 水凝胶复合材料设计为具有控释效果。FTIR 研究显示反应内容之间绝对没有相互作用。释放动力学证实非菲克扩散（异常）释放为一级，Higuchi 和 Korsmeyer-Peppas 似乎是最适合的动力学模型。研究得出结论，高度稳定、多孔、pH 响应的 PMA 水凝胶复合材料设计为具有控释效果。FTIR 研究显示反应内容之间绝对没有相互作用。释放动力学证实非菲克扩散（异常）释放为一级，Higuchi 和 Korsmeyer-Peppas 似乎是最适合的动力学模型。研究得出结论，高度稳定、多孔、pH 响应的 PMA 水凝胶复合材料设计为具有控释效果。
