Efficacy and safety of once-daily, extended-release hydrocodone in individuals previously receiving hydrocodone/acetaminophen combination therapy for chronic pain
Abstract
BACKGROUND: Hydrocodone/acetaminophen combination analgesics are frequently prescribed for chronic pain management; however, acetaminophen presents potential hepatotoxicity to patients and thus dose limitations. These opioid medications are also widely abused. Once-daily, single-entity hydrocodone (Hysingla™ ER tablets [HYD]) is a novel formulation with abuse-deterrent properties for the management of chronic pain and represents a suitable option for those patients receiving analgesics containing the same opioid analgesic, hydrocodone. This post-hoc analysis evaluated the efficacy and safety of HYD in patients whose primary pre-study analgesic was hydrocodone/acetaminophen analgesics (23-31% of the study populations).
METHODS: Data were analyzed from two Phase III trials, a 12-week randomized, placebo-controlled trial (RCT) and an open-label, 52-week trial. In both trials, a dose-titration period with HYD was followed by respective periods of fixed-dose double-blind (randomized controlled trial [RCT]) or open-label, flexible-dose maintenance treatment. Pain intensity was assessed using a numerical rating scale (0-10, 0 = no pain). For the RCT, primary and sensitivity analyses of pain scores used different approaches to handle missing data. Safety data for both studies were summarized.
RESULTS: In the RCT, the mean baseline pain score was 7.3. Pain relief was greater with HYD than placebo during double-blind treatment. In the open-label, flexible-dose trial, the majority of…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
