Abstract
Disclosed herein are novel drug carriers including a non-aqueous pH dependent release system and a non-aqueous pH dependent reassembly/assembly and reabsorption/absorption system. The carriers are capable of pH dependent release of biologically active agents and assembly or reassembly when the carrier transitions from a low pH environment, to a high pH environment and back to a low pH environment.
