Safety and performance of current abuse-deterrent formulations

ABSTRACTIntroduction: Prescription opioid abuse is now an epidemic that has forced the government and industries to take initiatives. These include developing abuse-deterrent formulations (ADFs), issuing regulatory guidances and allocating massive budgets to ensure the safety and effectiveness of these medications.Areas covered: This review covers the regulatory guidance on evaluation and labeling of the branded and generic ADFs.
