Abstract
Introduction: Multi-modal analgesia is desirable for the management of acute pain since it can provide effective pain relief at lower doses, thereby aiding tolerability. Co-crystal of tramadol-celecoxib (CTC) provides effective analgesia in models of acute pain. Co-crystallization can alter the pharmacokinetics of individual components, potentially improving tolerability. We sought to better understand the safety and tolerability of CTC in patients with acute postoperative pain.
Methods: We conducted a pooled analysis of safety data from three phase 3 randomized controlled trials in adults with acute moderate-to-severe pain following oral surgery, bunionectomy, and elective abdominal hysterectomy. We present data for CTC 200 mg twice daily (BID) and its comparators: tramadol 50 mg four times daily (QID) (one trial), tramadol 100 mg QID (two trials), celecoxib 100 mg BID (two trials), and placebo (three trials).
Results: In total, n = 551 patients received CTC 200 mg BID, n = 183 received tramadol 50 mg QID, n = 368 received tramadol 100 mg QID, n = 388 received celecoxib 100 mg BID, and n = 274 received placebo. The prevalence of adverse events (AEs) related to study drug up to 48 h was numerically lower with CTC 200 mg BID (35.9%) than with tramadol 50 mg QID (47.5%) and 100 mg QID (44.8%) but greater than with celecoxib 100 mg BID (12.4%) and placebo (20.4%). The most frequent AEs related to study drug up to 48 h were somnolence, nausea, dizziness, and vomiting, which occurred more frequently in patients receiving tramadol 100 mg QID than in those receiving CTC 200 mg BID.
Conclusion: CTC 200 mg BID appears to be better tolerated than tramadol 100 mg QID, possibly because of reduced total exposure to tramadol. This may contribute to a more favorable benefit-risk profile for CTC versus individual components, making it a promising treatment for acute pain.
期刊介绍：
Pain and Therapy is an international, open access, peer-reviewed, rapid publication journal dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of pain therapies and pain-related devices. Studies relating to diagnosis, pharmacoeconomics, public health, quality of life, and patient care, management, and education are also encouraged.
Areas of focus include, but are not limited to, acute pain, cancer pain, chronic pain, headache and migraine, neuropathic pain, opioids, palliative care and pain ethics, peri- and post-operative pain as well as rheumatic pain and fibromyalgia.
The journal is of interest to a broad audience of pharmaceutical and healthcare professionals and publishes original research, reviews, case reports, trial protocols, short communications such as commentaries and editorials, and letters. The journal is read by a global audience and receives submissions from around the world. Pain and Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of all scientifically and ethically sound research.
