<;P>;PROBLEM TO BE SOLVED: To provide a metal complex medicine capable of readily carrying out oral administration and solving conventional technical problems even in bond strength with molecule of medicine and affinity for molecule of medicine without using enormous carrier molecules having magnetism as a carrier and readily making practicable, and to provide a drug delivery system using the medicine. <;P>;SOLUTION: The pharmaceutical compound is composed of an inorganic compound which is a metal complex having an organic compound or an anticancer property and has magnetism by modification of the side chain or/and crosslinkage between side chains. An apparatus for guiding the pharmaceutical compound guides the compound into a prescribed affected area by utilizing magnetism of the pharmaceutical compound. A disposition detector is a magnetism-detecting apparatus for detecting magnetism of the pharmaceutical compound. <;P>;COPYRIGHT: (C)2008,JPO&INPIT
