ObjectiveTo make Singopicroside hydrophilic gel matrix tablets and to examine the factors affecting their dissolution rates.

目的制备丁香苦苷亲水凝胶骨架片，并对其释药影响因素进行了研究。

Results the nifedipine sustained-release beads was hydrophilic gel frame, drug diffusion and frame erosion was the release mechanisms in vitro.

结果本文自制硝苯地平缓释微丸为亲水性凝胶骨架制剂，体外释放机制包括药物扩散和骨架溶蚀两种作用。

Hydroxypropylmethylcellulose(HPMC), as hydrophilic gel matrix, is widely applied in the study of controlled release and sustained release preparations.

羟丙基甲基纤维素（ HPMC）作为构成亲水凝胶骨架片的主要控释、缓释材料广泛用于药物的控释和缓释制剂的研究。

ALG microcapsule is a hydrophilic gel, as a drug carrier, it is easily leaked out encapsulated hydrophilic small molecular drugs, and cause a low encapsulate rate and a short releasing time.

ALG微胶囊为亲水性凝胶，其作为药物载体，包裹水溶性小分子药物，常发生泄漏，造成药物包封率较低，释放时间过短。

RESULTS:The diffusive rate of diclofenac sodium from the two kinds of hydrophilic polymer gel was higher than that of diclofenac acid.

结果：在亲水的高分子凝胶基质中，离子形式的双氯芬酸钠扩散速率大于分子形成的扩散速率。
