Disclosed are crosslinked particles (e.g., microparticles) that are capable of storing and releasing drugs. The particles can be macroparticles, microparticles, or nanoparticles and can be composed of polyester backbones. The particles can be loaded with a drug. The particles can degrade in vivo to release the drug. The particles can be prepared by crosslinking functionalized polyester backbones and loaded with a given drug. The particles of the present disclosure can be injected with a syringe. In some embodiments, the particles of the present disclosure are administered in connection with a surgery and release the drug after the site of the surgery for a period of 1-6 months.
所公开的是能够储存和释放药物的交联颗粒(如微粒)。这些颗粒可以是大颗粒、微粒或纳米颗粒,可以由聚酯骨架组成。颗粒中可以装载药物。颗粒可在体内降解,释放药物。颗粒可通过交联官能化聚酯骨架制备,并负载给定的药物。本公开的微粒可用注射器注射。在某些实施方案中,本公开的微粒与手术一起给药,并在手术部位后释放药物,持续 1-6 个月。
