The review comes as regulators disclosed that the number of doctors who completed voluntary training programs is less than half that targeted by the agency. A panel of FDA advisers meets next week to review risk-management plans put in place nearly four years ago to reduce misuse and abuse of long-acting painkillers, powerful opioid drugs at the center of a national wave of abuse and death. Under the current risk-management programs, drugmakers fund voluntary training for physicians on how to safely prescribe their medications.
