The present invention relates to polymeric medical articles comprising the antiinfective agents chlorhexidine and triclosan. It is based, at least in part, on the discovery that the synergistic relationship between these compounds permits the use of relatively low levels of both agents, and on the discovery that effective antimicrobial activity may be achieved when these compounds are comprised in either hydrophilic or hydrophobic polymers. It is also based on the discovery that chlorhexidine free base and triclosan, used together, are incorporated into polymeric medical articles more efficiently. Medical articles prepared according to the invention offer the advantage of preventing or inhibiting infection while avoiding undesirably high release of antiinfective agent, for example into the bloodstream of a subject.
本发明涉及含有抗感染药剂
洗必泰和
三氯生的聚合物医疗用品。本发明至少部分基于以下发现:这些化合物之间的协同关系允许使用相对较低
水平的两种制剂,并且发现当这些化合物包含在亲
水性或疏
水性聚合物中时,可以实现有效的抗菌活性。此外,本发明还发现无
氯己定碱和
三氯生一起使用时,能更有效地融入聚合物医疗用品中。根据本发明制备的医疗用品具有预防或抑制感染的优点,同时避免了抗感染剂的过高释放,例如释放到受试者的血液中。
