In addition, the latest scientific findingson substances and productsalready marketed are discussed.

In the journal's special section "Biotechnology in Drug Research" investigators present their studies, results, and experience with therapeutics of biotechnological origin. Like with classical drugs, themes cover all the steps from discovery and development up to clinical research. Arzneimittel-Forschung / Drug Research publishes original papers in German or English; due to the journal's international distribution, the publishers recommend the use of English.
