Compositions and methods for the treatment of tuberculosis, as well as other mycobacterial and gram positive bacterial infections are disclosed. These compositions contain a highly potent and selective oxazolidinone encapsulated with high efficiency to maximize dosing potential of low toxicity drugs, and are stable in the presence of plasma. The compositions are long circulating and retain their encapsulated drug while in the circulation following intravenous dosing to allow for efficient accumulation at the site of the bacterial or mycobacterial infection. The high doses that can be achieved when combined with the long circulating properties and highly stable retention of the drug allow for a reduced frequency of administration when compared to daily or twice daily administrations of other drugs typically utilized to treat these infections.
揭示了用于治疗结核病以及其他分枝杆菌和革兰氏阳性细菌感染的组合物和方法。这些组合物含有一种高效、选择性的奥
沙林酮,高效地封装以最大限度地发挥低毒性药物的剂量潜力,并在血浆存在的情况下保持稳定。这些组合物在静脉注射后在循环中长时间循环,并保留其封装的药物,以便在细菌或分枝杆菌感染部位有效积累。与通常用于治疗这些感染的其他药物的每日或每日两次给药相比,结合长时间循环特性和高度稳定的药物滞留,可以实现高剂量,从而降低给药频率。
