一般說明

聚 (丙交酯-乙交酯)(PLGA)是一种可生物降解的聚合物,用于制备聚合物微球。这些聚合物在体内通过其酯骨架水解为无毒产物而降解,这些无毒产物可由肾脏排出,或通过生物化学途径分解为CO2 和水。PLGA微球被广泛应用于包裹药物分子,并可用作长效缓释药物制剂。

應用

聚 (丙交酯-乙交酯)(PLGA)可用于制造缓释药物递送体系,例如,它可用于包裹抗炎亲脂药物阿托伐他汀。

Peptide or protein degradation often occurs when water flows into the dosage form. The aim of this study was to investigate the effect of water on exenatide acylation in poly(lactide-co-glycolide) (PLGA) microspheres. Exenatide-loaded PLGA microspheres were incubated at different relative

Melatonin, a neurohormone secreted by the pineal gland, is able to modulate intraocular pressure (IOP). The aim of this study was to generate nanoparticle (NPs) sustained release formulations that allow to extend the pre-corneal residence time of melatonin, thus prolonging

Chronic pain after inguinal hernia repair occurs in 16% to 62% of patients. The underlying mechanism probably involves sensory nerve damage and abnormal healing that might be influenced by the materials chosen for the procedure. We hypothesize that nonabsorbable sutures

Materials that combine facile synthesis, simple tuning of degradation rate, processability, and biocompatibility are in high demand for use in biomedical applications. We report on acetalated dextran, a biocompatible material that can be formed into microparticles with degradation rates that

Interest in utilizing biodegradable polymers for biomedical applications has grown since the 1960s.

Synthetic aliphatic polyesters dominate resorbable biomaterials in clinical use.

商业生物材料已停滞不前超过30年的时间,因为很少有材料能够成功地从实验台过渡到临床使用。合成型脂族聚酯因其悠久的历史和获得美国食品药品监督管理局(FDA)批准的记录,一直在可吸收生物材料领域占据主导地位。

AliAliphatic polyesters, including polylactide and polyglycolide, are biodegradable polymers widely used in medical applications.
