Summary
Percy Menzies was there at the beginning. A pharmacist by training, he helped launch naltrexone at DuPont in the 1980s and later served as an associate product director when it was approved for alcohol dependence. He believed they had a medication that could change millions of lives. Instead, he watched it run into resistance from doctors, treatment centers, and some of the most powerful organizations in the field. Percy eventually left DuPont and founded the Assisted Recovery Centers of America, where he built his own treatment model around the medication he had spent years trying to get people to accept. This is the surprising firsthand story of how a medication proven to help people struggled to reach those who could benefit from it, who stood in its way, and why, more than 40 years later, Percy believes naltrexone’s moment may finally be here.
