Abstract: Transdermal iontophoresis per se may not be able to achieve significant permeation of large peptides like insulin, thereby necessitating the use of combination strategies involving chemical enhancers and iontophoresis. The study investigated effect of pre-treatment with commonly used vehicles such as ethanol (EtOH), propylene glycol (PG), water and their binary combinations, dimethyl acetamide (DMA), 10% dimethyl acetamide in water, ethyl acetate (EtAc) and isopropyl myristate (IPM) on insulin iontophoresis.
