Zohydro ER (hydrocodone bitartrate extended release) / Currax - LARVOL DELTA

Painful decision-making at FDA (Expert Opin Drug Saf) - "Additionally, the rewording of the labeled indication (from 'moderate to severe pain' to 'severe enough pain') for extended-release opioid analgesics, in an attempt to provide clarity, resulted in an equally if not more vague statement of appropriate use. Furthermore, the postmarketing requirement for continued data regarding safety and efficacy have been affirmed by FDA but some of the proposed means to acquire those data will likely result in unclear answers and may have undesired consequences."
