Pharmaceutical cocrystals – cocrystals that contain a drug molecule – can improve the physicochemical performance of drugs, making the prescription you take on doctor’s orders more effective. The properties of any crystal are inherently dependent upon composition and crystal packing, so if you have control over these two things you have control over the physicochemical properties.
Following an explosion of interest and work in this area over the last decade, Michael Zaworotko and colleagues from the Department of Chemical and Environmental Sciences at the University of Limerick review the current state of the literature on pharmaceutical cocrystals.
They cover four areas: nomenclature, design using hydrogen-bonded supramolecular synthons, methods of discovery, and synthesis and development of pharmaceutical cocrystals as drug products. Usefully, they present seven recent case studies on the clinical improvements that can be observed.
A review in 2004 asked the question “Do pharmaceutical co-crystals represent a new path to improved medicines?” Zaworotko and colleagues, having reviewed the last decade of literature, can answer in the affirmative. To find out why the answer to this question is “yes” read this review today!
