Hebrew University Researchers Win Kaye Prize For Gastro-Retentive Sustained Release Drug Delivery System

07.06.2004


Despite advances made in “sustained delivery” drug delivery technologies in recent years, a problem still persists in trying to obtain controlled release of a wide variety of medications that have only a “narrow absorption window” in the upper part of the intestines. That is, these drugs are absorbed rather quickly after being swallowed, negating the beneficial effects of “once-a-day” medication.



Now, researchers at the Hebrew University School of Pharmacy have developed a new technology, which they call Gastro-Retentive Dosage Form (GDRF), that “hangs” drugs in the stomach for an extended period. This is accomplished through a matrix consisting of a multilayer polymeric film that contains the active compound embedded in the polymer, surrounded by a rigid frame.

The matrix is “folded” into a standard size gelatin capsule. After swallowing, the matrix “unfolds” itself. Because of its protective polymer coating, the drug remains in the stomach for an extended period, accompanied by a slow and steady release, rather than being absorbed quickly.

The technology can serve as a platform to entrap large amounts of a variety of active agents and drugs containing difference physiochemical properties. It has especial significance for various drugs – including those that treat AIDS, as well as cardiovascular and central nervous system disorders – for which a steady level of medication dosage is critical.

For their work in developing the technology, Prof. Amnon Hoffman and Prof. Michael Friedman of the Department of Pharmaceutics at the Hebrew University School of Pharmacy and Dr. Eran Lavy of the Hebrew University Koret School of Veterinary Medicine have been named as winners of the Kaye Award for Innovations, to be presented on June 8 at the 67th meeting of the university’s Board of Governors.

The technology has been patented through the Hebrew University’s Yissum Technology Transfer Company, and initial steps towards commercial development are under way at the Intec-Pharma startup company in Jerusalem’s Har Hachotzvim high-tech industrial area.

The Kaye Innovation Awards have been given annually since 1994. Isaac Kaye of England, a prominent industrialist in the pharmaceutical industry, established the awards to encourage faculty, staff, and students of the Hebrew University to develop innovative methods and inventions with good commercial potential which will benefit the university and society.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Klima-Satellit: Mit robuster Lasertechnik Methan auf der Spur

Hitzewellen in der Arktis, längere Vegetationsperioden in Europa, schwere Überschwemmungen in Westafrika – mit Hilfe des deutsch-französischen Satelliten MERLIN wollen Wissenschaftler ab 2021 die Emissionen des Treibhausgases Methan auf der Erde erforschen. Möglich macht das ein neues robustes Lasersystem des Fraunhofer-Instituts für Lasertechnologie ILT in Aachen, das eine bisher unerreichte Messgenauigkeit erzielt.

Methan entsteht unter anderem bei Fäulnisprozessen. Es ist 25-mal wirksamer als das klimaschädliche Kohlendioxid, kommt in der Erdatmosphäre aber lange nicht...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
