One example of this is with the [[dissociative]] drug [[DXM]]. DXM, or dextromethorphan, is the isomer that rotates clockwise in plane-polarised light. It has antitussive (cough suppressant) and dissociative effects. Levomethorphan is the isomer that rotates anti-clockwise in plane-polarised light. This difference in rotation leads to different effects to DXM; levomethorphan is an opioid painkiller. | One example of this is with the [[dissociative]] drug [[DXM]].
