ReviewOpioid formulations in development designed to curtail abuse: who is the target?
Opioids are increasingly prescribed for chronic cancer and noncancer pain, and misuse, abuse, and diversion have risen dramatically. Formulations are being developed with the intent to curtail abuse through physical barriers that resist alteration, inclusion of excipients that antagonize opioid effects when altered, and other technologies. ⋯ Emerging opioid formulations may prove useful to minimizing prescription opioid abuse, but the magnitude of their clinical utility and societal impact will be unknown until epidemiological studies can be conducted. Realistic expectations for what the new formulations can achieve are encouraged.
