Randomized Controlled Trial
Sucralfate as an Adjunct to Analgesia to Improve Oral Intake in Children With Infectious Oral Ulcers: A Randomized, Double-Blind, Placebo-Controlled Trial.
We hypothesized that sucralfate along with oral analgesics (acetaminophen or ibuprofen) administered in the emergency department leads to a clinically significant improvement in oral intake in children with acute infectious oral ulcers. ⋯ Sucralfate as an adjunct to oral analgesics was not superior to placebo in improving oral intake in children with acute oral infectious ulcers.

Patient, Provider, and Clinic Characteristics Associated with Opioid and Non-Opioid Pain Prescriptions for Patients Receiving Low Back Imaging in Primary Care.
To describe characteristics of patients, providers, and clinics associated with opioid or non-opioid pain medication prescribing patterns for patients who received lower spine imaging in primary care clinics. ⋯ After adjusting for factors that could affect prescribing, the strongest differences observed in pain-medication prescribing were across racial categories and for patients with previous pain prescriptions. Further research is needed to understand these differences and to optimize prescribing.

Randomized Controlled Trial
Effects of pupillary reflex dilation-guided opioid administration on remifentanil and morphine consumption during laparoscopic surgery: A randomised controlled trial.
Analysis of pupillary reflex dilation (PRD) assesses the balance of nociception--antinociception. Laparoscopic surgery induces haemodynamic variations that are misleading. During laparoscopy, PRD guidance helps differentiate haemodynamic changes because of excess nociception from secondary changes related to the reflex release of endocrine factors. ⋯ When PRD is used to differentiate between haemodynamic events arising from noxious stimuli and those events because of other nonsurgical stimuli, then intra-operative remifentanil administration is reduced intra-operatively during laparoscopic surgery but there was no change in postoperative morphine consumption.

Randomized Controlled Trial
A Phase 1, Randomized, Double-blind, Placebo-controlled, Crossover Study to Evaluate the Pharmacodynamic Effects of VX-150, a highly selective NaV1.8 inhibitor, in Healthy Male Adults.
To evaluate the analgesic potential, safety, tolerability, and pharmacokinetics of VX-150, a pro-drug of a highly selective NaV1.8 inhibitor, in healthy subjects. ⋯ Results of this proof-of-mechanism study are supportive of the potential of VX-150, a highly selective NaV1.8 channel inhibitor, to treat various pain indications.

Randomized Controlled TrialRifampin Reduces the Plasma Concentrations of Oral and Intravenous Hydromorphone in Healthy Volunteers.
Several opioids are metabolized by the inducible cytochrome P450 (CYP) 3A isozymes. Coadministration with strong inducers of drug metabolism, such as rifampin, can dramatically reduce systemic exposure to these opioids. As the CYP metabolism of hydromorphone is of minor importance, we studied in healthy volunteers whether hydromorphone would be an effective analgesic for patients who concomitantly receive the prototypical enzyme inducer rifampin. ⋯ Rifampin significantly reduces the concentrations of oral and intravenous hydromorphone. This interaction is due to an increase in the first-pass and systemic metabolism of hydromorphone, likely involving induction of uridine 5'-diphospho- glucuronosyltransferase enzymes by rifampin. The enhancement of hydromorphone elimination should be considered when managing pain of patients who are treated with strong enzyme inducers.
