ABSTRACT:
Delivery systems for releasing macromolecular active agents to a body site at a controlled rate for a prolonged period of time, comprising a cholesteric matrix permeable to passage of the macromolecular active agent by diffusion, are disclosed. The cholesteric matrix comprises cholesterol powder and cholesterol prills optionally in combination with a binding agent and a lubricating agent. The macromolecular active agent is dispersed throughout the matrix; macromolecules suitable for release from this delivery system have molecular weights of about 1300 to about 75,000 and are at least very slightly soluble in water.
