Aim: Long-term safety and effectiveness of a once-daily, single-entity, extended-release formulation of hydrocodone bitartrate (HYD) for the treatment of moderate to severe noncancer and nonneuropathic pain among patients with and without concurrent depression/anxiety at baseline. Materials & methods: Post hoc analysis. Results: HYD demonstrated a safety profile consistent with μ-opioid agonists: Serious adverse events in 12% patients with depression/anxiety including four deaths; 6% without depression/anxiety including one death. All pain scores declined by ≥2 points and mean daily HYD dose remained stable in both subgroups. Conclusion: More serious adverse events occurred among patients with comorbid depression/anxiety at baseline than among those without. HYD provided stable and effective analgesia for 52 weeks among chronic pain patients with and without comorbid depression/anxiety at baseline.
