    AbstractOpioid usage during chronic nonmalignant pain has increased substantially over the past two decades. Prescription opioids have become the second most misused drug in the USA and prescription opioid abuse has escalated into a widespread public health problem. It is hoped that abuse-deterrent opioid formulations will take an important role in reducing opioid abuse, misuse and diversion. Embeda (sustained-release morphine sulfate with sequestered naltrexone)represents a new opioid formulation with an intended abuse-deterrent feature, now available on the market. Although Embeda seems to be a successful formulation by passing the efficacy trial, safety trial, pharmacokinetic study and abuse liability study, etc., it will require some long-term prospective epidemiological studies to substantiate fully its abuse-deterrent benefit. Embeda represents a new opioid formulation, adding to our arsenal to treat moderate to severe pain and playing its potential role in discouraging opioid abuse, misuse and diversion. Faced with an overwhelmingly expanding public health burden due to prescription opioid abuse, clinicians should always keep in mind the balance of maximizing pain relief and minimizing prescription opioid abuse.© 2011 Informa UK, Ltd
