A new way of developing painkillers has been discovered by researchers from Charité – Universitätsmedizin Berlin. A team of scientists used computational simulation to analyze interactions at the cell’s docking sites for painkillers. These sites are called the opioid receptors. When their prototype of a morphine-like molecule was used in an animal model, it was able to produce substantial pain relief in inflamed tissues while healthy tissues remained unaffected. This suggests that the severe side effects currently associated with these types of painkillers could be avoided.
