The pharmacokinetics of methotrexate (MTX) in rabbit's skin and plasma after iv-bolus and iontophoretic delivery at different current densities was studied. Linear microdialysis probes were introduced into the upper dorsal shaved skin of tranquilized rabbits. Commercially available patches were used to deliver MTX for 1 h at different current densities(More)
The purpose of this project was to develop and validate a pharmacokinetic model and to quantify the rate and extent of distribution between plasma and skin of two beta-lactam antibiotics, amoxicillin (AMX) and cefuroxime (CFX), which are frequently administered systemically to treat skin and skin structure infections. Dosing regimens are usually based on(More)
The objective was to quantify acyclovir (ACV) exposure in the dermis following iontophoresis of nontraditional (pH-11 gels) and traditional (neutral cream) topical formulations of ACV. Given that the application time of a formulation on the skin can be significantly reduced with iontophoresis, the use of formulations optimized for iontophoretic delivery was(More)
Systemic bioavailability is usually determined from plasma data. However, when plasma is difficult to access, as in young children, alternative methods would be particularly beneficial. The present study investigates the possibility of calculating systemic bioavailability fraction (F) from skin concentrations measured by two microdialysis (MD) sampling(More)
BACKGROUND Amitriptyline (AMT) is a tricyclic antidepressant with demonstrated local analgesic effects in human skin. AIM We investigated the feasibility and mechanisms of iontophoretic delivery of AMT to rabbit dermis and plasma. METHOD Two microdialysis probes were inserted into the upper dorsal shaved skin of tranquilized rabbits. After 1 hour, an(More)
