The present invention provides compositions and methods for delivery of therapeutic agents across an barrier. The compositions include a therapeutic agent (e.g., antimicrobial agent, antibiotic, or anesthetic agent), a permeation enhancer which increases the flux of the therapeutic agent across the barrier, and a matrix forming agent. The matrix forming agent forms a gel at a suitable gelation temperature and rheological properties for use in drug delivery, and in some cases, the gelation temperature and rheological properties are not significantly changed from those of the composition without the permeation enhancer. The invention also provides a matrix forming agent and compositions thereof. Such compositions are particularly useful in the treatment of otitis media. Methods of treatment, methods of delivery, and kits for the compositions described herein are also provided.
本发明提供了跨屏障递送治疗剂的组合物和方法。这些组合物包括治疗剂(如抗菌剂、抗生素或麻醉剂)、增加治疗剂通过屏障的通量的渗透促进剂和基质形成剂。基质形成剂在合适的凝胶温度和流变特性下形成凝胶,用于给药,在某些情况下,凝胶温度和流变特性与不含渗透增强剂的组合物相比没有明显变化。本发明还提供了一种基质形成剂及其组合物。这种组合物特别适用于中耳炎的治疗。本发明还提供了用于本文所述组合物的治疗方法、给药方法和试剂盒。
