Abstract
The chiral opioid analgesic tramadol was patented (1962) as a cis- and trans-racemates mixture. A first chiral switch led to the (+/-)-cis-(1RS,2RS) racemate, patented and approved as Tramal (1980), preferred over the (+)-cis-(1R,2R)-enantiomer. Consecutive chiral switches of (+/-)-cis-tramadol to (+)-cis-(1R,2R)-tramadol/salts were patented. This Viewpoint calls for developing (+)-cis-(1R,2R)-tramadol medicines and recognizing tramadol medicines as potential psychedelics to overcome the spreading tramadol crisis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
