Abstract
This invention provides the controlled-release method for a pharmaceutical composition comprising of metals in the drug carrier. The specific chelator is used to trigger the release of active pharmaceutical ingredients from chelating complex micelles. The drug release rate and half-life can also be controlled by manipulating the dosing sequence and the concentration of metal and specific chelator.
