Drug addiction has often proved resistant to the best efforts for treatment. New York-based startup Medicasafe Inc. hopes to provide another tool in the arsenal to boost opioid use disorder (OUD) treatment. Rather than send a recovering addict home every couple of weeks with an unmonitored and uncontrolled supply of buprenorphine and naloxone, it has developed a drug-device combination product that digitally enables and tracks patient retrieval of those drugs.
