A Non-Linear Isothermal Model for Migration of Drugs in Wet Granulations

Pages 1701-1708 | Published online: 20 Oct 2008
 

Abstract

A non-linear isothermal model for migration of drugs during drying period in wet granulations is proposed and some of its important properties are introduced. The mathematical expression is derived from physical fundamentals in such a way that computer implementation is feasible. The model includes the well-known Rumpf and Washburn equations, and it can be used as a suitable starting point for numerical simulation experiments.
