Oral-Absorption-Enhancing Drug-Delivery Technology
The authors examine an oral-absorption-enhancement technology based on surface-active materials to increase apical membrane fluidity in vitro.

Volume 35, pp. s12-s14


The GIPET technology is an advanced-stage permeation enhancement oral drug-delivery platform based on enhancers that have been studied in cells, tissues, rodents, dogs, and humans to demonstrate their ability to promote drug absorption, safety, reversibility, and mechanism of action. The technology is suitable for a wide range of different molecule types as evidenced by the preclinical and clinical studies showing enhanced intestinal absorption.


The authors thank David Brayden, professor at the University College Dublin in Ireland for critical reading of the manuscript. The authors also want to acknowledge that the work of Edwin Walsh is funded by an Irish Research Council for Science, Engineering and Technology (IRCSET)–Industry Partnership between the Irish Government and Merrion Pharmaceuticals.
