In vivo transdermal delivery of leuprolide using microneedles and iontophoresis.


The objective of this study was to investigate the use of iontophoresis and/or microneedles to enhance transdermal delivery of leuprolide acetate in vivo in hairless rats. Microporation was achieved using 500 μm long maltose microneedles and pore formation was confirmed using dye binding studies, histology studies, calcein imaging studies, pore permeability… (More)
