Over-the-counter heartburn drug Zantac pulled in US, Canada

A single measurement replaces laborious analytical procedures during the development and production of active ingredients for medicines Spectroscopy based on 'vibrational circular dichroism' (VCD) can significantly improve the practical determination of the structure of chiral molecules. Researchers at the University of Amsterdam have improved VCD so that a single measurement suffices to determine the absolute configuration of many-centre chiral molecules that are often used as active ingredients in medicines. The same VCD measurement also provides insight into contamination levels and is therefore at the same time suitable for quality control in pharmaceutical production. In a recent paper in the renowned scientific journal Analytica Chimica Acta, Wybren Jan Buma, professor of Molecular Photonics, reports remarkable research performed together with colleagues and four sophomore chemistry students. The paper contains the analysis results of dydrogesterone, a widely used hormonal medicine for menstr
