2B), and when the vehicle cannot be considered well stirred. We examine each of these models in terms of expressions for amount penetrating, flux, and, where possible, summary parameters such as mean absorption time, normalized variance, peak time for flux, and maximum flux. A. In Vitro Skin Permeability Studies with a Constant Donor Concentration and Sink Receptor Conditions Most in vitro skin permeability studies are carried out assuming that both a) the concentration of solute in a vehicle applied to the skin and b) the sink Page 6 * Page 7 conditions provided by the receptor remain constant over the period of the study.
Accordingly, the amount of solute absorbed across the skin Q(t) at various times t is defined in the Laplace domain as: (37) Of particular interest in this overview is the case of a constant donor concentration (infinite donor) and sink receptor. Q(s) is then defined by: (38) Page 18 Figure 8A shows the effect of kc (as defined by a = kctd) on Q(t) versus time profile. Note that, at long times, the linear portion of Q(t) [defined by Eq. (38)] versus t profile describes a steady-state flux Jss and lag time (lag): (39) (40) Thus, both the slope and lag of the steady-state portion of a Q(t) versus t plot depend on kc.
