The potential of liposome-encapsulated antibiotics for prolonging drug application intervals was investigated by using a murine model of chronic lethal Mycobacterium avium infection. Liposomal encapsulation of amikacin, but not of ciprofloxacin, resulted in high and sustained drug levels in infected tissues, exceeding the minimal inhibitory concentration for M. avium for at least 28 days. As a consequence, once-weekly and even once-monthly treatments with liposomal amikacin significantly reduced bacterial replication in infected tissues and extended the survival time of infected mice.
通过使用慢性致死性鸟分枝杆菌感染的小鼠模型,研究了脂质体包裹抗生素延长药物应用间隔的潜力。阿米卡星脂质体包裹而非环丙沙星脂质体包裹,导致感染组织中药物水平高且持续,超过鸟分枝杆菌的最低抑菌浓度至少28天。因此,每周一次甚至每月一次用脂质体阿米卡星治疗可显著减少感染组织中的细菌复制,并延长感染小鼠的存活时间。
