Drug Delivery

This group is located at the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS)


While considering the confusing flood of drugs in the pharmacies it is hard to believe in a lack of medication. But there are still many infectious diseases and also cancer that cannot be treated sufficiently. During a medical treatment it is essential that the drug arrives at the envisaged body region. Read more about the research of the department “Drug Delivery” on techniques for the correct distribution of novel drugs.

  • Kleine Teile – große Wirkung: Pharmazeuten des HIPS schleusen Medikamente zielsicher durch den Körper
    Wie kommt ein Medikament dahin, wo es wirken soll? Das ist eine der zentralen Fragen bei der Entwicklung neuer Wirkstoffe. Denn es reicht nicht, ein tolles neues Medikament gegen Darminfektionen im Reagenzglas zu haben – es muss auch dort hin gelangen, wo die Krankheit stattfindet. Mit Transportmolekülen schleusen die Pharmazeuten des HZI diese Wirkstoffe durch unseren Körper – über Barrieren, durch passende Lücken und an gefährlichen Stellen vorbei.
