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.
本发明提供了一种可选的药物释放的大分子和寡聚物,其中药物分子和NO释放基团与可吸收的大分子或寡聚物链相连,易于水解降解,而大分子或寡聚物由安全和生物相容的分子重复单元组成,例如乙二醇酸、乳酸、己内酯和p-二噁烷酮。此外,本发明涉及从NO和药物释放大分子或寡聚物中控制释放一氧化氮(NO)和/或药物分子。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制剂。
