ABSTRACT:
A pharmaceutical preparation is provided for oral or anal administration containing, in addition to a selected pharmacologically active agent, at least one magnetic material capable of reacting to an externally acting magnetic field of an electronic monitoring device, so that after administration to a patient, a signal is produced that is selectively detectable by such a monitoring device, thus providing information on whether the preparation has been taken or not by the patient and/or facilitates locating the preparation or the magnetic material in the region of the gastrointestinal tract of the patient.
