Ketorolac Versus Other Non-Steroidal Anti-Inflammatory Drugs for the Management of Acute Pain: Comparative Clinical Effectiveness TITLE: Ketorolac versus Other Non-Steroidal Anti-Inflammatory Drugs for the Management of Acute Pain: Comparative Clinical Effectiveness DATE: 16 January 2017 RESEARCH QUESTION What is the comparative clinical effectiveness of ketorolac versus any other non-steroidal anti- inflammatory drug for the management of acute pain? KEY FINDINGS Four randomized controlled trials were identified regarding the comparative clinical effectiveness of ketorolac versus any other non-steroidal anti-inflammatory drug for the management of acute pain. METHODS A limited literature search was conducted on key resources including PubMed, The Cochrane Library, University of York Centre for Reviews and Dissemination (CRD) databases, Canadian and major international health technology agencies, as well as a focused Internet search. To Methodological filters were applied to limit retrieval to health technology assessments, systematic reviews, meta-analyses, randomized controlled trials, non-randomized studies, and guidelines. Where possible, retrieval was limited to the human population. The search was also limited to English language documents published between January 1, 2012 and December 20, 2016. Internet links were provided, where available. The summary of findings was prepared from the abstracts of the relevant information. Please note that data contained in abstracts may not always be an accurate reflection of the data contained within the full article.

Table 1: Selection Criteria Population Any patient with acute pain Intervention Ketorolac (Toradol) Comparator Non-steroidal anti-inflammatory drugs (e.g., ibuprofen, naproxen, etc.); Excluding aspirin and celecoxib Outcomes Clinical effectiveness, pain management, adverse events Study Designs Health technology assessments, systematic reviews, meta-analyses, randomized controlled trials, non-randomized studies RESULTS Rapid Response reports are organized so that the higher quality evidence is presented first. Therefore, health technology assessment reports, systematic reviews, and meta-analyses are presented first. These are followed by randomized controlled trials, and non-randomized studies. Four randomized controlled trials were identified regarding the comparative clinical effectiveness of ketorolac versus any other non-steroidal anti-inflammatory drug for the management of acute pain. No relevant health technology assessments, systematic reviews, meta-analyses, or non-randomized studies were identified. Additional references of potential interest are provided in the appendix. OVERALL SUMMARY OF FINDINGS Four randomized controlled trials1-4 (RCTs) were identified comparing the effectiveness of ketorolac to other non-steroidal anti-inflammatory drugs. For the management of acute low back pain, one RCT1 determined that sublingual ketorolac was non-inferior to naproxen for the reduction of pain over five days. A higher percentage of patients in the ketorolac group reported improved pain relief within the first 60 minutes after the initial dose. Adverse events included heartburn, nausea, and vomiting.1 Two RCTs2,4 compared intravenous (IV) ketorolac with injectable diclofenac and placebo for the management of post-operative pain. In one RCT,2 acute pain was managed within six hours following orthopedic surgery.2 Mean pain scores were significantly improved in the ketorolac and diclofenac groups when compared with placebo. Significantly better pain scale scores, a lower opioid requirement, and faster onset of pain relief were observed in the diclofenac group as compared to the ketorolac group.2 A second RCT4 compared IV ketorolac with injectable diclofenac and placebo for the management of acute pain following abdominal or pelvic surgery. Both the ketorolac and diclofenac groups reported a significant reduction in pain and requirements for additional morphine when compared with placebo. One serious treatment- related adverse event was reported in the ketorolac group.4 One RCT3 compared the effectiveness of intramuscular ketorolac with diclofenac for the management of pain associated with acute renal colic in the emergency department. A significant difference in pain scores between groups was reported only at 15 minutes following treatment and favored the ketorolac group. There was no significant difference in pain relief between groups at any other time point. No significant differences in adverse events were observed between groups.3 Ketorolac versus Other Non-Steroidal Anti-Inflammatory Drugs for the Management of Acute Pain 2 REFERENCES SUMMARIZED Health Technology Assessments No literature identified.

  • Efficacy and Safety of Celecoxib
    ORIGINAL PAPER Nagoya J. Med. Sci. 77. 81 ~ 93, 2015 EFFICACY AND SAFETY OF CELECOXIB COMPARED WITH PLACEBO AND ETODOLAC FOR ACUTE POSTOPERATIVE PAIN: A MULTICENTER, DOUBLE-BLIND, RANDOMIZED, PARALLEL-GROUP, CONTROLLED TRIAL NAOKI ISHIGURO1, MD, PhD; AKIO HANAOKA2, MS; TOSHIYUKI OKADA2, MS; and MASANORI ITO3, PhD 1Department of Orthopedic Surgery, Nagoya University Graduate School of Medicine, Nagoya, Japan 2Clinical Development 1, Astellas Pharma Inc., Tokyo, Japan 3Global Data Science, Astellas Pharma Global Development Inc., Northbrook, IL, US ABSTRACT Celecoxib is a nonsteroidal anti-inflammatory drug (selective cyclooxygenase-2 inhibitor) that is widely used. The efficacy and safety of celecoxib for treatment of acute postoperative pain were evaluated in Japanese patients. The objective was to assess whether celecoxib showed superiority over placebo treatment and non-inferiority versus etodolac (another selective cyclooxygenase-2 inhibitor) that has been widely used for the management of acute pain. A multicenter, double-blind, randomized, parallel-group, controlled study was performed, in which 616 patients with postoperative pain received celecoxib, etodolac, or placebo. Their impressions of study drug efficacy (overall assessment) and pain intensity were evaluated. Based on each patient’s overall assessment of pain, the efficacy rate was 63.7% in the placebo group, 76.2% in the celecoxib group, and 68.0% in the etodolac group, with these results demonstrating superiority of celecoxib to placebo and noninferiority versus etodolac. The efficacy rate was significantly higher in the celecoxib group than in the etodolac group. There were no adverse events specific to celecoxib, and the safety of celecoxib was similar to that of placebo. Celecoxib was superior to etodolac for controlling acute postoperative pain.

  • (Ketorolac Tromethamine Tablets) Rx Only WARNING TORADOL
    TORADOL ORAL (ketorolac tromethamine tablets) Rx only WARNING TORADOLORAL (ketorolac tromethamine), a nonsteroidal anti-inflammatory drug (NSAID), is indicated for the short-term (up to 5 days in adults), management of moderately severe acute pain that requires analgesia at the opioid level and only as continuation treatment following IV or IM dosing of ketorolac tromethamine, if necessary. The total combined duration of use of TORADOLORAL and ketorolac tromethamine should not exceed 5 days. TORADOLORAL is not indicated for use in pediatric patients and it is NOT indicated for minor or chronic painful conditions. Increasing the dose of TORADOLORAL beyond a daily maximum of 40 mg in adults will not provide better efficacy but will increase the risk of developing serious adverse events. GASTROINTESTINAL RISK Ketorolac tromethamine, including TORADOL can cause peptic ulcers, gastrointestinal bleeding and/or perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Therefore, TORADOL is CONTRAINDICATED in patients with active peptic ulcer disease, in patients with recent gastrointestinal bleeding or perforation, and in patients with a history of peptic ulcer disease or gastrointestinal bleeding. Elderly patients are at greater risk for serious gastrointestinal events (see WARNINGS). CARDIOVASCULAR RISK NSAIDs may cause an increased risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. This risk may increase with duration of use. Patients with cardiovascular disease or risk factors for cardiovascular disease may be at greater risk (see WARNINGS and CLINICAL STUDIES). TORADOL is CONTRAINDICATED for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery (see WARNINGS).

What is the most important information I should know about medicines called Non-Steroidal Anti- Inflammatory Drugs (NSAIDs)? NSAID medicines may increase the chance of a heart attack or stroke that can lead to death. This chance increases: • with longer use of NSAID medicines • in people who have heart disease NSAID medicines should never be used right before or after a heart surgery called a “coronary artery bypass graft (CABG).” NSAID medicines can cause ulcers and bleeding in the stomach and intestines at any time during treatment. Ulcers and bleeding: can happen without warning symptoms may cause death The chance of a person getting an ulcer or bleeding increases with: ▪ taking medicines called "corticosteroids” and “anticoagulants” ▪ longer use ▪ smoking ▪ drinking alcohol ▪ older age ▪ having poor health NSAID medicines should only be used: • exactly as prescribed • at the lowest dose possible for your treatment • for the shortest time needed What are Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)? NSAID medicines are used to treat pain and redness, swelling, and heat (inflammation) from medical conditions such as: different types of arthritis menstrual cramps and other types of short-term pain Who should not take a Non-Steroidal Anti-Inflammatory Drug (NSAID)? Do not take an NSAID medicine: • if you had an asthma attack, hives, or other allergic reaction with aspirin or any other NSAID medicine • for pain right before or after heart bypass surgery Tell your healthcare provider: • about all of your medical conditions.

  • Clinical Outcomes of Aspirin Interaction with Other Non-Steroidal Anti- Inflammatory Drugs: a Systematic Review
    J Pharm Pharm Sci (www.cspsCanada.org) 21, 48s – 73s, 2018 Clinical Outcomes of Aspirin Interaction with Other Non-Steroidal Anti- Inflammatory Drugs: A Systematic Review Zuhair Alqahtani and Fakhreddin Jamali Faculty of Pharmacy and Pharmaceutical Science, University of Alberta, Edmonton, Alberta, Canada. Received, March 16, 2018; Revised, March 30, 2018; Accepted, April 25, 2018; Published, April 27, 2018. ABSTRACT - Purpose: Concomitant use of some non-Aspirin nonsteroidal anti-inflammatory drugs (NANSAIDs) reduces the extent of platelet aggregation of Aspirin (acetylsalicylic acid). This is while many observational studies and clinical trials suggest that Aspirin reduces cardiovascular (CV) risk attributed to the use of NANSAIDs. Thus, the therapeutic outcome of the interaction needs to be assessed. Methods: We searched various databases up to October 2017 for molecular interaction studies between the drugs and long-term clinical outcomes based on randomized clinical trials and epidemiological observations that reported the effect estimates of CV risks (OR, RR or HR; 95% CI) of the interacting drugs alone or in combinations. Comparisons were made between outcomes after Aspirin alone, NANSAIDs alone and Aspirin with naproxen, ibuprofen, celecoxib, meloxicam, diclofenac or rofecoxib. Results: In total, 32 eligible studies (20 molecular interactions studies and 12 observational trials) were found. Conflicting in vitro/in vivo/ex vivo platelet aggregation data were found for ibuprofen, naproxen and celecoxib. Nevertheless, for naproxen, the interaction at the aggregation level did not amount to a loss of cardioprotective effects of Aspirin. Similarly, for ibuprofen, the results overwhelmingly suggest no negative clinical CV outcomes following the combination therapy. Meloxicam and rofecoxib neither interacted with Aspirin at the level of platelet aggregation nor altered clinical outcomes.
