Objective To assess the in vivo cutaneous bioavailability of iodiconazole in a topical formulation. Methods Iodiconazole cream was topically administrated to the ventral forearms of 10 healthy volunteers for 1 hour, and the excess formulation was removed. The stratum corneum (SC) at the application sites was tape-stripped immediately or at different time points, quantified gravimetrically, and extracted for analysis. Together with concomitant transepidermal water loss (TEWL) measurement, SC drug concentration-depth profiles were reproducibly determined and fitted mathematically to obtain the SC-vehicle partition coefficient (K) and a first-order rate constant (D/L2) related to iodiconazole diffusivity. The main pharmacokinetic parameters were calculated by Drug and Statistics software. With these parameters, the uptake of iodiconazole of time into SC was assessed. The variation of iodiconazole concentrations in stratum corneum post-removal of the formulation was also investigated. Results The mean values of
