摘要：

The present invention relates to non-cross-linked micelles as delivery vehicles for steroid compounds and more particularly to a polycaprolactone-b-poly(ethylene oxide) copolymer micelle as a delivery vehicle for steroids. The delivery system comprises a population of diblock copolymer non-cross-linked micelles, each micelle defining a non-cross-linked core for containing the steroid compound. The delivery system of the present invention maintains the release of the steroid compound in a patient having a deficient steroid level.
