Randomized Controlled Trial
Efficacy and safety of single-dose DFN-15 for treatment of acute postsurgical dental pain: a randomized, double-blind, placebo-controlled study.
The analgesic efficacy and safety of DFN-15, a new oral liquid formulation of celecoxib with more rapid absorption than the capsule, were evaluated in the treatment of acute pain in adult patients after dental surgery. In this randomized, double-blind, placebo-controlled, dose-ranging study, 120 otherwise healthy adults who underwent the extraction of bilateral impacted mandibular third molar teeth and experienced moderate to severe pain postsurgery were randomly assigned, in a 1:1:1:1 ratio, to receive one dose of either placebo or DFN-15 at 3 doses: 62.5, 125, and 250 mg. Participants were evaluated at prespecified time points over 8 hours after study drug administration, using several instruments, including the 11-point Numerical Pain Rating Scale, 5-point Pain Relief Scale, and 5-point Treatment Satisfaction Scale. ⋯ All 3 doses of DFN-15 were significantly superior to placebo in SPID6 (least square mean difference over placebo: -756.6, -1120.7, and -1355.1, P < 0.0001 for all comparisons). In addition, DFN-15 was generally superior to placebo in other endpoints, including reduction of pain intensity, speed and magnitude of pain relief, treatment satisfaction, and rescue medication use. DFN-15 was similar to placebo in the incidence of adverse events with no apparent dose-related effects.

Reports have emerged of abrupt tapering among recipients of long-term prescription opioids to conform new prescribing guidelines. We conducted a population-based, repeated cross-sectional time-series study among very high-dose (≥200 MME) opioid recipients in Ontario, Canada, to examine changes in the monthly prevalence of rapid tapering from 2014 to 2018, defined as recipients experiencing either a ≥50% reduction in daily doses or abrupt discontinuation sustained for 30 days. Interventional autoregressive integrated moving average models were used to test for significant changes following key guidelines and drug policies and programs. ⋯ Although the prevalence of abrupt opioid discontinuation was lower, similar trends were observed. Our sensitivity analysis examining long-lasting rapid tapering found similar trends but lower prevalence, with no changes in complete discontinuation. These temporary increases in rapid tapering events highlight the need for improved communication and evidence-based resources for prescribers to minimize negative consequences of evolving policies and guidelines.

In 2019, the American College of Rheumatology conditionally recommended tramadol and conditionally recommended against nontramadol opioids for patients with hip and knee osteoarthritis. Although tramadol is known to be less prone to opioid use disorders, little is known about the differing magnitude of negative clinical outcomes, health care resource utilization, and costs of tramadol relative to nontramadol opioids. Administrative claims records for commercially insured patients with osteoarthritis who were prescribed opioids were used to compare clinical and cost outcomes during a 3-year follow-up period by conducting a pre-post analysis and a matched case-cohort analysis. ⋯ Finally, in both analyses, the nontramadol cohort incurred higher levels of inpatient and emergency department visits and all-cause costs during the 3-year follow-up period. However, tramadol patients incur a higher incremental change (+$24,013) in costs relative to their pretreatment baseline compared with nontramadol (+$18,191). These real-world findings demonstrated lower risks with tramadol relative to other opioids, albeit risks and increased health care costs were present with tramadol, highlighting the need for further strategies to improve outcomes.

Opioids relieve acute pain, but there is little evidence to support the stability of the benefit over long-term treatment of chronic noncancer pain. Previous systematic reviews consider only group level published data which did not provide adequate detail. Our goal was to use patient-level data to explore the stability of pain, opioid dose, and either physical function or pain interference in patients treated for 12 months with abuse deterrent formulations of oxycodone and hydrocodone. ⋯ In a secondary analysis of 985 patients with a measured physical function, 338 (34.3%) maintained their physical function in addition to pain and opioid dose. Of 2040 patients with pain interference measured, 788 (38.6%) met criteria in addition. In a carefully controlled environment, about one-third of patients successfully titrated on opioids to treat chronic noncancer pain demonstrated continued benefit for up to 12 months.

Prescription opioids remain an important driver of the opioid crisis in the United States. The purpose of this study was to examine recent changes in opioid prescribing patterns in the Military Health System (MHS) which is a nationwide health system service active duty military personnel and civilian beneficiaries. All patients prescribed opioid analgesics by MHS providers and filled at MHS pharmacies between 2014 and 2018 were identified. ⋯ The proportion of prescriptions written for >90 OMEs per day declined 21%. Declines in opioid prescriptions and quantities were observed in nearly all specialties over the study period. The results of this study suggest a broad-based shift towards less opioid prescribing.
