The present invention provides NO and, optionally, drug releasing macromers and oligomers wherein the drug molecule and NO releasing moiety are linked an absorbable macromer or oligomeric chain susceptible to hydrolytic degradation and wherein the macromer or oligomer comprises of repeat units derived from safe and biocompatible molecules such as glycolic acid, lactic acid, caprolactone and p-dioxanone. Furthermore, the present invention relates to controlled release of nitric oxide (NO) and/or drug molecule from a NO and drug releasing macromer or oligomer. Moreover, the present invention also relates to medical devices, medical device coatings and therapeutic formulations comprising of nitric oxide and drug releasing macromers and oligomers of the present invention.
本发明提供了一氧化氮(NO)和可选的药物释放的大分子和寡聚物,其中药物分子和一氧化氮释放部分通过可吸收的大分子或可水解降解的寡聚物链连接,并且大分子或寡聚物由来自诸如乙醇酸、乳酸、己内酰胺和对二恶烷等安全且生物相容的分子的重复单元组成。此外,本发明还涉及从一氧化氮和/或药物分子释放的大分子或寡聚物控制释放一氧化氮(NO)。此外,本发明还涉及包含本发明的一氧化氮和药物释放大分子和寡聚物的医疗器械、医疗器械涂层和治疗方法。
