Analgesic Efficacy and Hematologic Effects of Robenacoxib in Mice.
    Journal of the American Association for Laboratory Animal Science : JAALAS, 2018, 05-01, Volume: 57, Issue:3

    NSAID analgesics may confound models that require inflammation to mimic disease development in humans. This effect presents a challenge for veterinary staff and investigators, because surgery is often necessary to create mouse models of disease and NSAID are first-line analgesics used to treat postoperative pain. We evaluated robenacoxib, a NSAID highly selective for cyclooxygenase 2, in a carrageenan paw edema (CPE) assay and surgical model of venous thrombosis (VT). We generated a mouse-specific dose-response curve by using the CPE assay for robenacoxib doses of 3.2, 10, 32 and 100 mg/kg SC. Electronic von Frey assay, calipers, and novel software for measuring open-field activity revealed that all robenacoxib doses provided, identified effective analgesia at 3 and 6 h, compared with saline. In addition, the 100-mg/kg dose had measurable antiinflammatory effects but yielded adverse clinical side effects. Because the 32-mg/kg dose was the highest analgesic dose that did not decrease paw swelling, we evaluated it further by using the same nociceptive and behavioral assays in addition to a novel nest-consolidation test, and assessment of blood clotting and hematologic parameters in the surgical VT model. A single preemptive dose of either 32 mg/kg SC robenacoxib or 5 mg/kg SC carprofen protected against secondary hyperalgesia at 24 and 48 h. Neither drug altered clot formation or hematology values in the VT model. The open-field activity software and our novel nest consolidation test both identified significant postoperative discomfort but did not differentiate between saline and analgesia groups. In light of these data, a single preemptive subcutaneous dose of 32 mg/kg of robenacoxib or 5 mg/kg of carprofen did not impede this VT mode but also failed to provide sufficient postoperative analgesia.

Effect of mucoprotective plant-derived therapies on damage to colonic mucosa caused by carprofen and robenacoxib administered to healthy dogs for 21 days.
    The veterinary quarterly, 2014, Volume: 34, Issue:4

    Non-steroidal anti-inflammatory drugs (NSAIDs) may cause gastrointestinal damage in dogs.. To determine the extent to which lansoprazole, liquorice extract, and a herbal solution exhibit protective effects on colonic mucosa when administered to dogs concurrently with the NSAIDs carprofen or robenacoxib.. Thirty-five healthy beagle dogs (15 male and 20 female) aged 13-14 weeks and weighing 4.3-5.5 kg at the beginning of the experiment were included. Endoscopy and biopsy of the caudal gastrointestinal tract were performed pretreatment and on the last day of a 21-day treatment period with (1) oral carprofen; (2) carprofen and the proton-pump inhibitor lansoprazole; (3) carprofen, liquorice extract, and a herbal solution that contained extracts of thyme, icelandic lichen, hyssop, and saponariae root; (4) robenacoxib; (5) robenacoxib and lansoprazole; (6) robenacoxib, liquorice extract, and herbal solution; or (7) an empty gelatin capsule. Statistical analyses were performed with the Kruskal-Wallis, Cochran's Q, and chi-squared test with p < 0.05 considered significant.. Both carprofen and robenacoxib tested damaged the colonic mucosa with most severe microscopic lesions following administration of robenacoxib with lansoprazole. The risk of histopathological lesions in the colon increased most rapidly in robenacoxib with lansoprazole (absolute risk increase -0.85) similar to robenacoxib only (-0.75), whereas the best result was recorded following the plant remedies together with carprofen (-0.15) and the plant remedies together with robenacoxib (-0.2).. Concurrent administration of liquorice extract and an herbal solution with robenacoxib was associated with decreased severity of the NSAID-induced mucosal lesions.

Robenacoxib vs. carprofen for the treatment of canine osteoarthritis; a randomized, noninferiority clinical trial.
    Journal of veterinary pharmacology and therapeutics, 2012, Volume: 35, Issue:2

    Robenacoxib is a member of the coxib class of nonsteroidal anti-inflammatory drugs (NSAID), with high selectivity for the cyclooxygenase (COX)-2 isoform of COX. In this study, the efficacy and tolerability of robenacoxib were compared with those of carprofen in canine osteoarthritis in a multi-centre, prospective, randomized, blinded, positive-controlled noninferiority clinical trial. Both drugs were administered orally once daily at recommended dosages: robenacoxib at 1-2 mg/kg (n = 125 dogs) and racemic carprofen at 2-4 mg/kg (n = 63 dogs) for a total of 12 weeks. The efficacy of the test compounds was assessed by veterinary investigators and owners using numerical rating scales at baseline and days 7, 14, 28, 56 and 84. In both groups, all scores were significantly (P < 0.0001) improved compared with baseline at all time points (days 7-84). Robenacoxib had noninferior efficacy to carprofen for the primary endpoint, the global functional disability, both for all dogs and for the subgroup of dogs in which robenacoxib was not administered during meals. Noninferiority was also demonstrated for three of six veterinary investigator secondary endpoints and four of six owner efficacy endpoints. For haematology and clinical chemistry variables, there were some significant differences from baseline levels but no differences between groups. There were no differences between groups in the frequencies of adverse events, which were reported in 46% dogs with robenacoxib and 52% with carprofen (P = 0.44), which were most frequently mild events affecting the gastrointestinal tract. In conclusion, noninferior efficacy and tolerability of robenacoxib compared with carprofen was demonstrated in dogs with osteoarthritis.

Comparison of oral robenacoxib and carprofen for the treatment of osteoarthritis in dogs: a randomized clinical trial.
    The Journal of veterinary medical science, 2012, Volume: 74, Issue:9

    The efficacy and tolerability of robenacoxib for the treatment of osteoarthritis in dogs were evaluated in a prospective, multicenter, randomized, noninferiority design clinical trial. A total of 32 dogs presenting with osteoarthritis were allocated randomly to receive, orally once daily for 28 days, either 1-2 mg/kg robenacoxib (n=21) or 3.5-5 mg/kg carprofen (n=11). Dogs were assessed by clinicians and owners using numerical rating scale scores at baseline and days 14 and 28. The primary efficacy endpoint was the global functional disability score, which was the sum of clinician scores for standing posture, lameness at walk, lameness at trot, willingness to raise the contralateral limb and pain at palpation. There was a good to excellent level of efficacy in both treatment groups. Differences between days 14 and 28 compared to day 0 were significant for all 11 clinician and owner scores for robenacoxib, and for 6 of 11 scores for carprofen. The efficacy of robenacoxib was numerically superior to carprofen for all 13 endpoints, but differences were not statistically significant. For the global functional disability score, the estimated efficacy of robenacoxib was 1.244 (95% confidence interval 0.555-2.493) relative to carprofen. The tolerability of both treatments was good as assessed from adverse events, clinical signs, and hematology and serum biochemistry variables. In conclusion, once daily administration of robenacoxib tablets had noninferior efficacy and tolerability compared to carprofen for the treatment of the clinical signs of osteoarthritis in dogs.

Inhibition of growth of canine-derived vascular endothelial cells by non-steroidal anti-inflammatory drugs and atrial natriuretic peptide.
    The Journal of veterinary medical science, 2019, May-31, Volume: 81, Issue:5

    This study investigated the direct effects of non-steroidal anti-inflammatory drugs (NSAIDs) and atrial natriuretic peptide (ANP) on canine-derived vascular endothelial cells (VECs). VECs were isolated and cultured from canine arteries and veins. The mRNA expressions of vascular endothelial growth factor receptor 2, cyclooxygenase-2, and natriuretic peptide receptor 1 were detected in the cultured VECs. The viability of the cultured VECs was reduced in a dose-dependent manner by meloxicam, carprofen, and robenacoxib. By contrast, dose escalations of ANP had only marginal influence on the viability of cultured VECs. NSAIDs may potentially serve as not only analgesic agents against cancerous and perioperative pain but also as adjuvant anti-angiogenic drugs in dogs with malignant tumors.

Compensatory cellular reactions to nonsteroidal anti-inflammatory drugs on osteogenic differentiation in canine bone marrow-derived mesenchymal stem cells.
    The Journal of veterinary medical science, 2014, Volume: 76, Issue:5

    The suppressive effects of nonsteroidal anti-inflammatory drugs (NSAIDs) on the bone healing process have remained controversial, since no clinical data have clearly shown the relationship between NSAIDs and bone healing. The aim of this study was to assess the compensatory response of canine bone marrow-derived mesenchymal stem cells (BMSCs) to several classes of NSAIDs, including carprofen, meloxicam, indomethacin and robenacoxib, on osteogenic differentiation. Each of the NSAIDs (10 µM) was administered during 20 days of the osteogenic process with human recombinant IL-1β (1 ng/ml) as an inflammatory stimulator. Gene expression of osteoblast differentiation markers (alkaline phosphatase and osteocalcin), receptors of PGE2 (EP2 and EP4) and enzymes for prostaglandin (PG) E2 synthesis (COX-1, COX-2, cPGES and mPGES-1) was measured by using quantitative reverse transcription-polymerase chain reaction. Protein production levels of alkaline phosphatase, osteocalcin and PGE2 were quantified using an alkaline phosphatase activity assay, osteocalcin immunoassay and PGE2 immunoassay, respectively. Histologic analysis was performed using alkaline phosphatase staining, von Kossa staining and alizarin red staining. Alkaline phosphatase and calcium deposition were suppressed by all NSAIDs. However, osteocalcin production showed no significant suppression by NSAIDs. Gene expression levels of PGE2-related receptors and enzymes were upregulated during continuous treatment with NSAIDs, while certain channels for PGE2 synthesis were utilized differently depending on the kind of NSAIDs. These data suggest that canine BMSCs have a compensatory mechanism to restore PGE2 synthesis, which would be an intrinsic regulator to maintain differentiation of osteoblasts under NSAID treatment.
