Randomized Controlled Trial Multicenter Study Clinical Trial
Slowing the titration rate of tramadol HCl reduces the incidence of discontinuation due to nausea and/or vomiting: a double-blind randomized trial.
Ultram [tramadol hydrochloride (HCl)] is a centrally acting analgesic that is widely prescribed for the treatment of moderate to moderately severe chronic pain. Although tramadol is generally well tolerated, some patients discontinue use early in the course of treatment because of nausea and vomiting. ⋯ This study demonstrated that a slower titration rate of tramadol HCl improves tolerability in patients who previously discontinued therapy due to nausea and/or vomiting. This study also demonstrates that the rate of titration of tramadol HCl rather than the target dose is the major determinant of tolerability.

Randomized Controlled Trial Multicenter Study Clinical TrialAnalgesia and sedation in preterm neonates who require ventilatory support: results from the NOPAIN trial. Neonatal Outcome and Prolonged Analgesia in Neonates.
Preterm neonates are exposed to multiple painful procedures after birth and exhibit acute physiological responses to pain. Occurrence of early intraventricular hemorrhage within 24 to 72 hours after birth suggests a role of pain and stress in the multifactorial causation of severe intraventricular hemorrhage and periventricular leukomalacia. We proposed that such neurologic outcomes in preterm neonates who require ventilatory support may be reduced by morphine analgesia or midazolam sedation compared with a placebo. ⋯ This pilot trial suggests that preemptive analgesia given by continuous low-dose morphine infusion may reduce the incidence of poor neurologic outcomes in preterm neonates who require ventilatory support. Limitations in the sample size of this pilot study suggest that these results should be confirmed in a large multicenter randomized trial.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Treatment of osteoarthritis pain with controlled release oxycodone or fixed combination oxycodone plus acetaminophen added to nonsteroidal antiinflammatory drugs: a double blind, randomized, multicenter, placebo controlled trial.
To compare the efficacy and safety of controlled release oxycodone given every 12 h around the clock with immediate release oxycodone-acetaminophen (APAP) given 4 times daily for osteoarthritis (OA) pain. ⋯ Controlled release oxycodone q12h and immediate release oxycodone-APAP qid, added to NSAID, were superior to placebo for reducing OA pain and improving quality of sleep. The active treatments provided comparable pain control and sleep quality. Controlled release oxycodone was associated with a lower incidence of some side effects.

Randomized Controlled Trial Multicenter Study Clinical TrialTreatment of menstruation-associated migraine with the nonprescription combination of acetaminophen, aspirin, and caffeine: results from three randomized, placebo-controlled studies.
This retrospective study sought to examine the benefits of the nonprescription combination of acetaminophen, aspirin, and caffeine (AAC; Excedrin Migraine, Bristol-Myers Squibb Company, New York, New York) for the treatment of menstruation-associated migraine compared with migraine not associated with menses. Data were derived from 3 double-masked, randomized, placebo-controlled, single-dose trials enrolling subjects who met the International Headache Society's diagnostic criteria for migraine with or without aura. Subjects with incapacitating disability (attacks requiring bed rest >50% of the time) and those who usually experienced vomiting > or =20% of the time were excluded. ⋯ The proportion of subjects who had 1 or more adverse experiences was significantly higher among those receiving AAC than among those receiving placebo (menstruation-associated migraine: AAC 26.4%, placebo 12.6%, P = 0.025; nonmenstruation-associated migraine: AAC 18.6%, placebo 11.4%, P = 0.005). Adverse experiences were similar in type and severity to those previously associated with single doses of acetaminophen, aspirin, or caffeine. Thus the nonprescription combination of AAC was highly effective in treating the pain, disability, and associated symptoms of both menstruation-associated migraine and migraine not associated with menses.
