Many studies have used pharmacokinetic (compartment) models for skin to predict or analyze dermal absorption of chemicals. Comparing these models is dif-®cult because the relationships between rate constants and the physicochemical parameters were not always de®ned clearly, simplifying assumptions b

✦ Synopsis
The limited contact time of absorbable drug with absorbing surfaces is, in some cases, a significant factor determining the fraction of the dose absorbed. A simple modification of customary linear compartmental models is presented to account for this situation, and a general input function in the Laplace domain for truncated first-order absorption is derived. An extension to series of truncated absorption processes is discussed.
