Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
The efficacy and safety of dipyrone (Novalgin) tablets in the treatment of acute migraine attacks: a double-blind, cross-over, randomized, placebo-controlled, multi-center study.
Dipyrone, an effective analgesic drug, is widely used in the management of headache. However, few studies have evaluated its efficacy and safety in migraine. We aimed to assess the efficacy and safety of 1 g dipyrone (Novalgin, two 500 mg tablets) on pain and related symptoms in acute migraine attacks with or without aura in a double-blind, cross-over, randomized, placebo-controlled, multi-center study design. ⋯ Both patient and physician evaluations were significantly in favor of dipyrone. Side effects were few and trivial in both groups. We conclude that dipyrone is an effective, safe and cost-effective option in acute migraine management.

Randomized Controlled Trial Multicenter Study Clinical Trial
Efficacy of oxymorphone extended release in postsurgical pain: a randomized clinical trial in knee arthroplasty.
Patients with moderate or severe pain following knee arthroplasty and washout from standard patient-controlled analgesia (PCA) were randomized to receive 20 mg of an extended-release (ER) oxymorphone formulation (n = 65) or placebo (n = 61) q12h for 1 day. Oxymorphone PCA was used as rescue analgesic. Oxymorphone ER provided significant improvements over placebo for most standard single-dose analgesic parameters, including mean total pain relief (TOTPAR) over 0 to 12 hours (19.30 vs. 13.72; p = 0.0056), as well as for all multiple-dose (24-h) efficacy assessments. ⋯ Oxymorphone ER was effective and generally well tolerated. A single dose was active from 2 hours until > or = 12 hours after administration. Comparisons with other oral opioids are warranted, especially in the setting of outpatient and day surgery.

Multicenter Study Clinical TrialObservational study on the use of remifentanil in general anesthesia. Drug utilisation research.
The use of remifentanil in routine clinical practice during the induction and maintenance of general anesthesia as well as the quality of awakening after anesthesia and post-operative pain management have been assessed. ⋯ This Drug Utilisation Research study demonstrated that the use of remifentanil according to its peculiar pharmacological profile, such as potent opioid with rapid onset and offset of action, the synergistic effect with propofol and the right management of post-operative pain are widely consolidated in Italian clinical practice.

Randomized Controlled Trial Multicenter Study Clinical Trial
Effects of morphine analgesia in ventilated preterm neonates: primary outcomes from the NEOPAIN randomised trial.
Opioid analgesia is commonly used during neonatal intensive care. We undertook the Neurologic Outcomes and Pre-emptive Analgesia in Neonates (NEOPAIN) trial to investigate whether pre-emptive morphine analgesia decreases the rate of a composite primary outcome of neonatal death, severe intraventricular haemorrhage (IVH), and periventricular leucomalacia (PVL) in preterm neonates. ⋯ Pre-emptive morphine infusions did not reduce the frequency of severe IVH, PVL, or death in ventilated preterm neonates, but intermittent boluses of open-label morphine were associated with an increased rate of the composite outcome. The morphine doses used in this study decrease clinical signs of pain but can cause significant adverse effects in ventilated preterm neonates.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialAnalgesic efficacy of preoperative parecoxib sodium in an orthopedic pain model.
The efficacy and safety of preoperative intravenous administration of parecoxib sodium, a novel parenteral prodrug of a cyclooxygenase-2 selective inhibitor, in treating postoperative pain resulting from bunionectomy were evaluated in 50 patients who were part of a larger cohort of orthopedic and podiatric patients. Following bunionectomy, the median time to rescue medication (survival analysis) was 4 hours 18 min (95% confidence interval, 3 hours 4 min to 4 hours 37 min) in the placebo group, 7 hours 5 min (95% confidence interval, 3 hours 20 min to >24 hours) in the 20-mg parecoxib sodium group, and 10 hours 43 min (95% confidence interval, 4 hours 42 min to 14 hours 7 min) in the 40-mg parecoxib sodium group (significant for 40-mg parecoxib sodium versus placebo). Four or more hours after surgery, the mean pain-intensity (categorical) score was significantly lower in both parecoxib sodium groups than in the placebo group. Preoperative administration of parecoxib sodium was well tolerated and significantly reduced postoperative pain in patients who had undergone bunionectomy.
