COX‐2‐selective inhibitors celecoxib and deracoxib modulate transient receptor potential vanilloid 3 channels The transient receptor potential vanilloid 3 (TRPV3) channel is a heat-sensitive ion channel, which is predominantly expressed in keratinocytes. TRPV3 channels are involved in numerous physiological and pathophysiological processes within the skin, including cutaneous nociception borate (2-APB), was efficaciously enhanced by deracoxib and celecoxib, two COX-2-selective inhibitors. They exerted their potentiating effect via a direct interaction with TRPV3 as evident from excised inside-out recordings. Structurally-related COX-2 inhibitors affected TRPV3 channel gating to a much lesser degree. Similar results were obtained in HEK293 cells stably expressing cyan fluorescent

Synergistic growth inhibitory effect of deracoxib with doxorubicin against a canine mammary tumor cell line, CMT-U27 Cyclooxygenase (COX) inhibitors have been shown to exert anti-angiogenic and anti-tumor activities on many types of malignant tumors. These anticancer properties make it worthwhile to examine the possible benefit of combining COX inhibitors with other anti-cancer agents . In the present study, we evaluated the potential of deracoxib (DER) in potentiating antitumor activity of doxorubicin (DOX) in canine mammary carcinoma cells (CMT-U27). DER (50-250 µM) enhanced the antiproliferative activity of DOX by reducing the IC50 (approximately 3- to 3.5 fold). Interaction analysis of the data showed that combinations of DOX at 0.9 µM with DER (100-250 µM) produced synergism in the CMT

Doxorubicin and deracoxib adjuvant therapy for canine splenic hemangiosarcoma: A pilot study Canine hemangiosarcoma (HSA) is a highly malignant tumor for which standard chemotherapy has done little to substantially improve survival. Cyclooxygenase-2 (Cox-2) plays a role in the formation, growth, and metastasis of tumors and inhibitors have demonstrated therapeutic benefit with certain canine cancers. In this prospective study, 21 dogs received adjuvant therapy combining the selective Cox-2 inhibitor deracoxib with doxorubicin, following splenectomy for HSA. The combination was well-tolerated with only low-grade gastrointestinal and hematologic toxicities noted. An overall median survival of 150 days (range; 21 to 1506 days) was noted. Although there was no significant difference in survival

was then used to identify potential binding sites on the DOP2 protein. A virtual screening of 235 anti-parasitic compounds was performed against DOP2 using PyRx 0.8. The screening demonstrated strong binding and interactions with active site residues of the DOP2 protein for five compounds: Diclazuril, Kaempferol, Deracoxib, Clindamycin, and Diaveridine. These compounds exhibited higher binding affinity values

Efficacy and safety of deracoxib for control of postoperative pain and inflammation associated with soft tissue surgery in dogs. To investigate the effectiveness and safety of deracoxib (Deramaxx®) administered at a dose of 1-2 mg/kg/day for 3 days for control of postoperative pain and inflammation associated with soft tissue surgery in dogs. Prospective, randomized, blinded, placebo-controlled , multi-center clinical study. Dogs (n = 34). Dogs undergoing soft tissue surgeries were randomly assigned to receive either deracoxib (n = 18) or placebo (n = 16) as a preoperative treatment and again once daily for 2 additional days after surgery unless removed from the study. Dogs were evaluated before surgery and again postsurgically at predetermined times using the Glasgow Composite Pain Scale

Effects of carprofen, meloxicam and deracoxib on platelet function in dogs. To determine effects of anti-inflammatory doses of COX-2 selective NSAIDs carprofen, meloxicam, and deracoxib on platelet function in dogs and urine 11-dehydro-thromboxane B2. Randomized, blocked, crossover design with a 14-day washout period. Healthy intact female Walker Hounds aged 1-6 years and weighing 20.5-24.2 kg . Dogs were given NSAIDs for 7 days at recommended doses: carprofen (2.2 mg kg(-1), PO, every 12 hours), carprofen (4.4 mg kg(-1), PO, every 24 hours), meloxicam (0.2 mg kg(-1), PO, on the 1st day then 0.1 mg kg(-1), PO, every 24 hours), and deracoxib (2 mg kg(-1), PO, every 24 hours). Collagen/epinephrine and collagen/ADP PFA-100 cartridges were used to evaluate platelet function before and during

The Effects of Piroxicam and Deracoxib on Canine Mammary Tumour Cell Line Cyclooxygenase (COX) inhibitors, already widely used for the treatment of pain and inflammation, are considered as promising compounds for the prevention and treatment of neoplasia. The aim of our study was to determine the direct antiproliferative effects of nonsteroidal anti-inflammatory drugs (NSAIDs), piroxicam and deracoxib, at a variety of concentrations as both single and combined treatments on canine mammary carcinoma cell line CMT-U27 and to understand the mechanisms of cell death. MTT assay was performed to determine cell viability, and flow cytometric analyses were performed to evaluate apoptosis and cell cycle alterations. Significant decrease in cell viability was observed at high concentrations

The effects of epidural deracoxib on the ground reaction forces in an acute stifle synovitis model. To evaluate the efficacy of epidurally administered deracoxib to mediate the signs of a sodium urate crystal-induced stifle synovitis in dogs, and to compare the efficacy of epidural versus subcutaneously administered deracoxib. Experimental, randomized, blinded, placebo-controlled modified cross -over design. Random source, adult, mixed breed dogs (n = 24; 14 males, 10 females). Sodium urate crystals were used to create a stifle synovitis model to evaluate the efficacy of deracoxib. Dogs were divided into 4 groups: 3 mg/kg epidural deracoxib, 1.5 mg/kg epidural deracoxib, 3 mg/kg subcutaneous deracoxib, and a placebo (vehicle for deracoxib). Force plate and subjective evaluations were made

Efficacy and safety of deracoxib for the control of postoperative pain and inflammation associated with dental surgery in dogs. The efficacy and safety of deracoxib administered at 1-2 mg/kg/day for 3 days was assessed for the control of postoperative pain and inflammation associated with dental surgery in dogs. Client-owned dogs scheduled for dental extractions were premedicated with butorphanol and randomly assigned to receive either deracoxib (n = 31) or placebo (n = 31) preoperatively and again once daily for 2 additional days. Dogs were evaluated prior to and after surgery using a modified Glasgow Composite Pain Scale (mGCPS). Dogs could be rescued at any time if they scored ≥4 on the mGCPS or in cases of obvious discomfort. Rescued dogs were considered treatment failures for determining

. Dogs received aspirin (5 mg/kg, PO, q 12 h), carprofen (4 mg/kg, PO, q 24 h), deracoxib (2 mg/kg, PO, q 24 h), and meloxicam (0.1 mg/kg, PO, q 24 h) for 10 days each, with an interval of at least 14 days between treatments. On days 0 and 10, blood was collected for platelet aggregation assays, thrombelastography, and measurement of lipopolysaccharide-stimulated prostaglandin E(2), platelet . Maximum amplitude and coagulation index increased after treatment with deracoxib. Plasma concentrations of prostaglandin E(2) decreased after treatment with carprofen or deracoxib, and platelet TXB(2) production increased after treatment with aspirin. Serum concentrations of the prostacyclin metabolite 6-keto-PGF-1alpha did not change significantly after treatment with any of the drugs, although

Effects of deracoxib or buffered aspirin on the gastric mucosa of healthy dogs. Use of cyclo-oxygenase-2 specific nonsteroidal anti-inflammatory drugs such as deracoxib has been advocated because of their anti-inflammatory actions and apparently low incidence of gastrointestinal adverse effects. Deracoxib will cause less endoscopically detectable gastric injury in dogs than aspirin , a nonselective nonsteroidal anti-inflammatory drug. Twenty-four random source healthy dogs. A randomized, placebo-controlled trial compared gastroscopic findings of dogs receiving placebo (q8h), aspirin (25 mg/kg PO q8h), or deracoxib (1.5 mg/kg QD, placebo ql2h) for 28 days. Gastroscopy on days -7, 6, 14, and 28 evaluated 4 regions of the stomach separately and visible lesions were scored. Dogs were observed

, dogs were administered 4 treatments consisting of an SC injection of an NSAID or control solution (day 0), followed by oral administration of an NSAID or inert substance for 4 days (days 1 through 4). Treatment regimens included carprofen (4 mg/kg) followed by inert substance; saline (0.9% NaCl) solution followed by deracoxib (4 mg/kg); carprofen (4 mg/kg) followed by carprofen (4 mg/kg ); and carprofen (4 mg/kg) followed by deracoxib (4 mg/kg). Hematologic, serum biochemical, and fecal evaluations were conducted weekly, and clinical scores were obtained daily. Endoscopy of the GIT was performed before and on days 1, 2, and 5 for each treatment. Lesions were scored by use of a 6-point scale. No significant differences existed for clinical data, clinicopathologic data, or lesion scores

Randomised controlled clinical trial for the use of deracoxib during intense rehabilitation exercises after tibial plateau levelling osteotomy. During intense physical exercise, the cyclo-oxygenase-2 (COX-2) pathway is upregulated which contributes to soreness. The aim of this study was to determine if there was a clinical affect of deracoxib (COX-2 selective antagonist) on dogs engaged in intense rehabilitation following tibial plateau levelling osteotomy for cranial cruciate ligament rupture. Our hypothesis was that dogs receiving deracoxib would demonstrate less lameness, better range-of-motion (ROM), and faster muscle mass recovery than the control dogs. Thirty dogs were randomised to the treatment (deracoxib at 1-2 mg/kg once daily by mouth) or control (no treatment) group. Outcomes

Effect of deracoxib, a new COX-2 inhibitor, on the prevention of lameness induced by chemical synovitis in dogs. Twenty-four healthy, mixed-breed hound-type dogs were evenly and randomly assigned to a placebo control group, one of four dosages of deracoxib (0.3, 1, 3, or 10 mg/kg), or carprofen (2.2 mg/kg). Oral dosing of placebo, carprofen, or deracoxib was done 30 minutes before intraarticular injection of urate crystal suspension for induction of synovitis. Ground reaction forces, subjective clinical lameness scores, pain, joint effusion, and quantitative pain threshold responses were measured in a blinded fashion before induction of synovitis and 2, 4, 6, 8, 12, and 24 hours after injection. The medium and high dosages of deracoxib were effective in preventing lameness and pain associated

Safety and tolerability of 3-week and 6-month dosing of Deramaxx (deracoxib) chewable tablets in dogs. Although non-steroidal anti-inflammatory drugs (NSAIDs) are effective in reducing pain and inflammation, these agents have adverse effects. Selective inhibitors of COX-2 are an alternative to traditional NSAIDs. Deramaxx [Novartis Animal Health US, Inc. (NAH), Greensboro, NC, USA] contains the selective COX-2 inhibitor, deracoxib, and is approved for the relief of pain and inflammation associated with orthopedic surgery and osteoarthritis in dogs. The safety of Deramaxx was evaluated in two target animal safety studies: 40 dogs (four dogs/sex/group) received 0, 4, 6, 8, or 10 mg/kg/day deracoxib once daily for 21 days; and 60 dogs (five dogs/sex/group) received 0, 2, 4, 6, 8, or 10 mg/kg/day

Firocoxib efficacy preventing urate-induced synovitis, pain, and inflammation in dogs. This positive-control study evaluated the efficacy of firocoxib versus carprofen, deracoxib, and meloxicam for the prevention of pain and inflammation in a urate crystal synovitis model of lameness. Lameness scoring and force plate gait analysis were used to assess efficacy. The resulting lameness scores
