Embodiment Construction

[0017] The drug delivery system of the present invention comprises a tablet, pill or capsule comprising a sound generating device which generates sound waves when said tablet, pill or capsule is exposed to the gastrointestinal system. The sound generating device includes, for example, a material that has the property of generating sound waves when it encounters water. Sound generating devices also include devices capable of generating sound waves via electronic, hydraulic or mechanical means. Examples of devices that use electronics to generate sound waves include general piezoelectric ultrasonic generators, voice coil systems, loudspeakers, and galvanic devices. Examples of devices that utilize hydraulics to generate sound waves include fluid vibrators and similar devices such as whistles. Examples of devices that use mechanical devices to generate sound waves include hammers, tuning forks, and other devices that use mechanisms to strike resonant objects. Preferably said ge...

Abstract

A tablet, pill or capsule containing a material which produces sound waves when the tablet, pill or capsule is exposed to the gastrointestinal system. A two step method for oral drug compliance monitoring. The first step is to ingest a tablet, pill or capsule containing a material which produces sound waves when the tablet, pill or capsule is exposed to the gastrointestinal system of a person. The second step is to detect the sound waves produced when the tablet, pill or capsule is exposed to the gastrointestinal system to confirm that the person has ingested the tablet, pill or capsule.

Description

[0001] Related Application Cross Reference [0002] This application claims the benefit of US Provisional Application No. 60 / 701,707, filed July 22,2005. technical field [0003] The present invention relates to oral medication compliance monitoring and in particular to devices for detecting materials formulated in pharmaceutical tablets, pills or capsules which generate sound waves when exposed to the environment of the gastrointestinal system. Background technique [0004] Patient non-adherence to their physician-prescribed medications leads to higher healthcare costs, higher complication rates, and increased drug waste. Non-adherence refers to not taking the prescribed dose at the prescribed time, which can lead to under-medication or overdose. In a survey of 57 studies of nonadherence, nonadherence ranged from 15% to as high as 95% of the total study population, regardless of medication, patient demographics, medications administered, or study method (Greenberg R N: Ove...
