Randomized Controlled Trial
Reduction of pain and functional disability over time in patients treated with zavegepant: a post-hoc analysis of the BHV3500-301 phase 3 randomized controlled trial.
Migraine is a disabling disorder that impacts 40 million people in the US. Zavegepant is the first calcitonin gene-related peptide (CGRP) receptor antagonist nasal-spray approved for the acute treatment of migraine with or without aura in adults. This study aimed to evaluate the proportion of patients in various pain and functional disability states over 48-h, for patients treated with zavegepant 10 mg nasal-spray versus placebo. ⋯ This post-hoc analysis demonstrates the benefit of zavegepant nasal spray over placebo on two patient-centric endpoints: time spent with pain freedom and normal functioning over 48-h post-dose. These data support the use of zavegepant for providing rapid and sustained freedom from migraine pain and freedom from migraine related disability, particularly for those who would benefit from the nasal CGRP formulation.

Randomized Controlled Trial
E-52862-A selective sigma-1 receptor antagonist, in peripheral neuropathic pain: Two randomized, double-blind, phase 2 studies in patients with chronic postsurgical pain and painful diabetic neuropathy.
We report the efficacy and safety of E-52862-a selective, sigma-1 receptor antagonist-from phase 2, randomized, proof-of-concept studies in patients with moderate-to-severe, neuropathic, chronic postsurgical pain (CPSP) and painful diabetic neuropathy (PDN). ⋯ These proof-of-concept studies validate the mode of action of E-52862, a selective sigma-1 receptor antagonist. In CPSP, E-52862 resulted in clinically meaningful pain relief. In PDN, reductions in pain intensity were seen with E-52862; high placebo response rates may have prevented differentiation between E-52862 and placebo. These findings are clinically relevant given that neuropathic pain is highly incapacitating, lacking effective treatments and representing a significant unmet medical need, and support further development of sigma-1 receptor antagonists for peripheral neuropathic pain.

Randomized Controlled TrialThe Effect of Intravenous Lidocaine, Ketamine, and Lidocaine-Ketamine Combination in Colorectal Cancer Surgery: A Randomized Controlled Trial.
Colorectal resections are associated with a pronounced inflammatory response, severe postoperative pain, and postoperative ileus. The aim of this study was to evaluate the main effects of lidocaine and ketamine, and their interaction in colorectal cancer (CRC) patients after open surgery. The interaction could be additive if the effect of 2 drugs given in combination equals the sum of their individual effects, or multiplicative if their combined effect exceeds the sum of their individual effects. We hypothesized that the combination of lidocaine and ketamine might reduce the inflammatory response additively or synergistically. ⋯ Our study results do not support the use of an intraoperative combination of lidocaine and ketamine in patients undergoing open surgery for CRC.

Randomized Controlled Trial Comparative Study
Comparison of Ultrasound-Guided Single-Injection Erector Spinae Plane Block, Retrolaminar Block and Paravertebral Block for Postoperative Analgesia in Single-Incision Video-Assisted Thoracoscopic Surgery: A Three-Arm, Double-Blind, Randomized Controlled Non-Inferiority Trial.
Effective postoperative analgesia is critical for thoracic surgery. This study compares the analgesic efficacy of the erector spinae plane block (ESPB), retrolaminar block (RLB), and paravertebral block (TPVB) in single-incision video-assisted thoracoscopic surgery (SITS). ⋯ ESPB and RLB provide noninferior analgesia compared with TPVB in SITS patients and are effective alternatives that enhance safety.
