WebCommonly, TEH could not be passive into the blood by percutaneous absorption, whereas the transdermal iontophoresis system improved the absorption of TEH in a grade extent. Compared with TDDS, transdermal iontophoresis, based on the original passive transport, can deliver drugs into the skin over a shorter time. Webiontophoresis parameters vary widely in clinical trials, ultimately affecting the ability to standardize clinical treatments to comprehensively evaluate the effectiveness of this modality. Therefore, it is important to mechanistically determine which component of the dosage, either time or current amplitude, has a greater affect on drug absorption.
WebConclusion: The transethosomal formulation of telmisartan enhanced its transdermal absorption and increased its bioavailability as well. Iontophoresis was used to increase maximum plasma concentration and reduce Tmax by half. Keywords: telmisartan, TEL, entrapment efficiency, EE, transethosomes, iontophoresis.
