摘要
Controlled drug release from a cylindrical matrix device has been investigated by a mathematical model. A simple cylindrical geometry with a small release hole is proposed as an excellent device for sustaining the drug efficacy. The calculated results have been verified by an experiment of benzoic acid release from a cylindrical agar gel.
