Interview with Yves De Koninck in le Soleil about recent discoveries about the mechanisms of opioid dependency

Yves De Koninck

Yves De Koninck recently gave an interview to Le Soleil newspaper about an important discovery published in Nature Medicine which offers new hope to people suffering from dependency to morphine and fentanyl. In the interview, Yves De Koninck indicates that the discovery his team participated in could help people get out of their dependent state by blocking withdrawal symptoms, without blocking the pain relieving effects of morphine and derived drugs.  

This study singled out the important role a protein called pannexin-1 plays in the development of withdrawal symptoms, and led the team to look for drugs that could block this protein.  They identified two molecules that could do this, probenecid, which is used to treat gout, and mefloquine, used to treat malaria.  As these two drugs are already approved for use in humans, this could greatly accelerate clinical trials, and if they are positive, the use of these drugs to treat dependent people.  The researchers also demonstrated, in rodents, that these drugs do not block the pain relieving effects of opioids such as morphine and  fentanyl.
