Controlled Drug Release Asymptotics [PDF]

SIAM Journal on Applied Mathematics, 1998
This paper deals with the solution of Higushi's model for controlled release of drugs when the solubility of the drug in the polymer matrix is a prescribed function of time. The model is described as a one-phase moving boundary problem which cannot be solved exactly. Two limits of the problem are considered.
