Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Postoperative pain management in patients undergoing major surgery after remifentanil vs. fentanyl anesthesia. Multicentre Investigator Group.
To determine if morphine sulphate was an effective transition analgesic in patients receiving a remifentanil-based anesthetic regimen. ⋯ Morphine sulphate regimens of 0.15 or 0.20 mg x kg(-1) administered 30 min before the end of surgery are equally effective transition regimens for inpatient procedures.

Randomized Controlled Trial Multicenter Study Clinical Trial
Evaluation of a novel solubilized formulation of ibuprofen in the treatment of migraine headache: a randomized, double-blind, placebo-controlled, dose-ranging study.
A total of 729 migraine sufferers with moderate to severe baseline pain evaluated a single 200, 400 or 600 mg dose of a new liquigel formulation of ibuprofen over 8 h. Ibuprofen liquigels were significantly superior to placebo for cumulative headache response (pain reduced to mild or none) from 0.5 (600 mg) or 1 h (200 and 400 mg) to 8 h. At 2 h, respective headache response rates for ibuprofen 200, 400 and 600 mg and placebo were 64%, 72%, 72% and 50%. ⋯ Ibuprofen liquigels were generally superior to placebo for reducing photophobia, phonophobia, or nausea (1-4 h) and for global evaluation. All doses were well tolerated. These data demonstrate that ibuprofen liquigels relieve the pain, ancillary symptoms, and limitation of activity, of migraine.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Postoperative pain control following remifentanil-based anaesthesia for major abdominal surgery.
Eighty patients undergoing major abdominal surgery using remifentanil-based anaesthesia were randomly allocated in a double-blind manner to receive an intravenous bolus of fentanyl, buprenorphine, morphine or piritramide 20 min before the end of surgery. A reduced dose was administered postoperatively when patients reported moderate pain. Subsequent analgesia was provided by patient-controlled analgesia (PCA). ⋯ At first pain assessment, 63% of patients reported no or mild pain; 80% of patients required the second opioid bolus, those receiving piritramide needed the bolus significantly later than patients receiving buprenorphine or fentanyl. First PCA requirement also occurred significantly later in the piritramide group. This technique provided effective postoperative pain relief and transition to routine PCA and did not compromise recovery.

Multicenter Study Comparative Study Clinical TrialA titrated morphine analgesic regimen comparing substance users and non-users with AIDS-related pain.
To compare morphine dosage and effectiveness in AIDS patients with/without prior substance use and pain, a prospective, open-label case series lasting 3-18 days was conducted in both outpatients and inpatients at major pain service teaching programs. Forty-four patients, 13 with prior drug use history, who had pain associated with HIV infection or its treatment were administered sustained-release morphine (SRM) every 12 hours. The dose was titrated to pain relief for a period of > or =3 consecutive days (associated with < or =2 immediate-release morphine tablets per 24 hours), or until the patient discontinued from the study or completed 18 study days. ⋯ Immediate-release morphine decreased in both; former users required more (P = 0.0006). These data suggest the utility of morphine for AIDS-related pain. Patients with a prior drug use history benefited but required substantially more morphine.

Acetaminophen controlled-release sprinkles versus acetaminophen immediate-release elixir in febrile children.
Current acetaminophen (APAP) formulations approved for antipyretic use in children require up to five doses/day, which compromise compliance and risk breakthrough fever over 4 hours after dosing. A total of 112 evaluable febrile children received oral APAP-equivalent doses of either one dose of APAP controlled release (CR) as sprinkles on applesauce or one dose q 4 hours x 2 of APAP immediate-release (IR) elixir in an 8-hour, double-blind, double-dummy, randomized, multicenter study. Prior or concurrent antibiotic use did not significantly affect either the magnitude or the pattern of temperature reduction during the 8-hour observation period. ⋯ Pharmacokinetic/pharmacodynamic modeling of APAP was performed in 8 patients with values in both treatments similar to previous results, except for expected differences in AUC0-infinity. Similar 8-hour temperature reduction for APAP-CR (one dose) and APAP-IR (two doses) demonstrates the efficacy of APAP-CR as an antipyretic in children 2 to 11 years of age. A decrease in the number of APAP daily doses and the prolonged antipyretic effect of APAP-CR may assist those who care for febrile children at home.
