The treatment of chronic pain remains an enormous challenge in the United States. Opioid analgesics are an important component of pharmacotherapy for chronic pain and have proven efficacy in the management of cancer and noncancer chronic pain. The newest addition to oral opioid pharmacotherapy is oral oxymorphone, a semisynthetic opioid agonist that is now available in oral immediate-release (IR) and extended-release (ER) formulations. This review discusses the pharmacology, pharmacokinetics, pharmacodynamics, pharmacotherapeutics, and clinical use of oral oxymorphone IR and ER formulations for the management of moderate to severe pain for different types of patients in a variety of settings. Two published studies evaluated the efficacy and safety of oxymorphone IR in patients with moderate to severe postoperative pain and demonstrated that it provides rapid and effective analgesia and is generally well tolerated. Six published randomized controlled trials and three published open-label studies evaluated the efficacy and safety of oxymorphone ER for chronic cancer or noncancer pain. These trials found analgesic efficacy and tolerability comparable to that provided by morphine controlled release (CR) or oxycodone CR; treatment effects with oxymorphone ER were durable for treatment periods of 12 weeks at the same dose or up to 1 year with little dose escalation. Titrated doses of oxymorphone ER were effective and generally well tolerated in both opioid-experienced and opioid-naïve patients. Aspects of oxymorphone metabolism and limited protein binding may simplify treatment in certain populations.

IntroductionData from two, identically designed, placebo-controlled, randomised, double-blind clinical trials (D1444C00132+D1444C00133) for once-daily extended-release quetiapine fumarate (QTP-XR) were pooled and analysed.ObjectiveEvaluate dose response, efficacy and safety for QTP-XR in schizophrenia.MethodsPost-hoc analysis of data from patients receiving QTP-XR 400, 600, 800 mg/day or placebo. Endpoints: least squares means (LSM) change from baseline to Day 42 in PANSS total and positive and negative subscale scores. No corrections for multiplicity were performed. Adverse events (AEs) were recorded.Results914 patients were included; PANSS scores were assessed in the MITT population (n = 889). LSM change from baseline in PANSS total score diverged significantly from placebo at: Day 14 for QTP-XR 800 mg/day (-15.3 vs -12.1 for placebo; p = 0.018); Day 21 for 600 mg/day (-17.3 vs -14.2; p = 0.039); Day 42 for 400 mg/day (-19.2 vs -15.4; p = 0.033).Jonckheere-Terpstra analysis of change in PANSS total score at Day 42 showed a significant QTP-XR dose response (p = 0.0196; p < 0.001 with placebo). PANSS positive scores diverged by Day 21 for both QTP-XR 800 (-5.7 vs -4.8; p = 0.049) and 600 mg/day (-5.8 vs -4.8; p = 0.046). PANSS negative scores diverged by Day 21 (-4.0 vs -3.2; p = 0.040) and 42 (-4.8 vs -3.6; p = 0.009) for QTP-XR 800 and 600 mg/day, respectively. AEs occurred in 59.4%, 66.5%, 62.1% and 56.2% of patients in the QTP-XR 800, 600, 400 mg/day and placebo groups, respectively. Most common AEs were somnolence, dry mouth, sedation, insomnia, dizziness, headache, constipation and nausea.ConclusionsQTP-XR was generally well tolerated and demonstrated efficacy that increased with dose in schizophrenia.Financial support: AstraZeneca.
