Compositions and methods for treating intracellular infections

摘要

A method of treating or preventing an intracellular infection in an animal comprising administering a first effective amount of a suitable drug contained in first biocompatible microspheres that have a diameter of less than or equal to about 10 microns, wherein the first microspheres release the suitable drug upon administration at a first effective rate. A second set of microspheres greater than 10 microns in diameter may also be administered to provide continuing systemic release of the drug.
