Abstract

Mathematical expressions have been derived to describe the rates of release of drugs from materials of cylindrical geometry. Included in the analysis is the possibility of a slow interfacial transfer step at the boundary of the controlled-release device. The use of micro-cylinders as controlled drug release devices is considered.
