Mechanism of action (3)

Species not stated (3)
  • Robenacoxib is a non-steroidal anti-inflammatory drug (NSAID) of the coxib class. Repeated subcutaneous administration is not associated with a bioaccumulation of robenacoxib. Although the bioaccumulation of robenacoxib metabolites has not been tested, radiolabeled studies suggest that the various unidentified metabolites are associated with a markedly longer elimination half-life (approximately 22 hours) as compared to that of the parent molecule. The activity of these metabolites has not been evaluated. The pharmacokinetics of robenacoxib injection does not differ between male and female dogs, and is linear over the range of 0.25-4 mg/kg in dogs. Absorption Peak blood concentrations of robenacoxib are attained rapidly after subcutaneous injection in dogs. After a dosage of 2 mg/kg, peak concentrations are generally achieved within 1-2 hours post-dose. After subcutaneous administration of 1 mg/kg to dogs, systemic bioavailability ranged from 67% to 100% (average = 89%). Distribution Robenacoxib has a relatively small volume of distribution (Vss of 174 to 336 mL/kg, average = 240 mL/kg), which is consistent with a drug that is extensively bound to plasma proteins. Based upon in vitro canine plasma samples, robenacoxib is approximately 98% bound to plasma proteins when spiked at concentrations ranging from 200 – 2000 ng/mL. The corresponding canine in vitro whole blood-plasma ratio in artificially spiked blood was 0.44. Biotransformation Robenacoxib is extensively metabolized by the liver in dogs. Apart from one lactam metabolite, the identity of other metabolites is not known in dogs. Robenacoxib is excreted predominately via the biliary route in dogs (approximately 65 %); therefore, the majority of the absorbed dose (parent drug and metabolites) is eliminated in the feces. The remainder of the administered dose is eliminated in urine via the kidneys. Elimination After intravenous administration to normal healthy dogs, robenacoxib is rapidly cleared from blood (CL of 0.61 to 1.13 L/kg/h, average = 0.81 L/kg/hr) with an elimination half-life ranging from 0.41 to 1.07 hrs. After subcutaneous administration to normal healthy dogs, the terminal half-life from blood was within 1 – 4 hrs.

  • In an inflammation model in cats, robenacoxib had analgesic, anti-inflammatory and anti-pyretic actions with a rapid onset of action (0.5 h). 1 In an in vitro whole blood assay in cats, robenacoxib demonstrated selective COX-2 inhibition. 2 The clinical relevance of this data has not been shown. Robenacoxib is an analog of diclofenac. Absorption Peak blood concentrations of robenacoxib are attained rapidly after subcutaneous injection in cats. After a dosage of 2 mg/kg, a Tmax of 1 hour, a Cmax of 1464 ng/ml and an AUC(0-inf) of 3128 ng.h/ml is obtained. The injection has a systemic bioavailability of 69%, which is higher than that observed after an equivalent oral dose. A slightly less than dose proportional increase in exposure was observed with an increase in dose (a 2X dose resulted in a 1.4X increase in drug exposure; a 3X increase in dose resulted in a 2.3X increase in drug exposure). Distribution Robenacoxib has a relatively small volume of distribution (mean Vss = 190 ml/kg) and is highly bound to plasma proteins (>99%). Robenacoxib persists longer in the inflammatory exudate of a tissue cage model than in blood. The median robenacoxib elimination half-life in exudate was about 27 hours versus 2.5 hours for blood. Metabolism Robenacoxib is extensively metabolized by the liver in cats. Apart from one lactam metabolite, the identity of other metabolites is not known. Elimination Robenacoxib is rapidly cleared from blood (mean clearance [CL] = 0.44 L/kg/h) with an elimination mean half-life (t1/2) of 1.1 hours after intravenous administration. After subcutaneous administration, the terminal half-life was 1.1 hour (range of estimated values was 0.9 hour to 1.6 hours). Repeated subcutaneous administration at dosages of 2-20 mg/kg produced no change in the blood profile, with neither bioaccumulation of robenacoxib nor enzyme induction. Elimination occurs predominantly through the biliary route (fecal and urinary excretion are 60 and 16.5% respectively). The pharmacokinetics of robenacoxib injection does not differ between male and female.

Adverse reactions (5)

Species not stated (5)
  • The controlled field study (see Effectiveness) included a total of 349 healthy male and female cats in the field safety analysis. Robenacoxib injection treated cats represented 7 breeds, 4 months to 7 years old, weighing 5.5-13.2 lbs. The following table shows the number of cats exhibiting each observation. Adverse Reactions in the Postoperative Pain Field Study Adverse Reaction* Robenacoxib N = 174** Control (0.9% physiologic saline) N =175 Incision site infection,dehiscence 9 0 Increased incision site bleeding 6 4 Vomiting 5 0 Decreased appetite 4 3 Lethargy (after day of surgery) 4 2 UTI 2 0 Coughing 1 0 Fever 1 0 Semiconscious*** 1 0 Soft stool, diarrhea 0 2 *Cats may have experienced more than one type or occurrence of an event during the study. **One robenacoxib cat suffered an anesthetic-related death. ***Semiconscious cat fully recovered. The most commonly reported adverse reactions in cats treated with robenacoxib injection were infected incision sites, increased incision site bleeding, vomiting, inappetence, and lethargy. Changes in the clinical pathology values were not considered clinically significant. An additional study was conducted in client-owned cats to evaluate robenacoxib injection at a dose of 2 mg/kg administered once daily for the control of postoperative pain and inflammation associated with an onychectomy (forelimbs only) and OVH or castration. The study was a masked, negative controlled, multi-center field study in which 187 cats were enrolled in a 2:1 ratio into two groups (127 cats treated with robenacoxib injection and 60 cats treated with saline). Adverse Reactions from Additional Field Study Adverse Reaction* Robenacoxib N = 127 Control (0.9% physiologic saline) N = 60 Surgical or venipuncture site bleeding 9 3 Leukocytosis 9 2 Fever 8 11 Lethargy (after day of surgery) 7 0 Vomiting 6 0 Anorexia/ decreased appetite 6 3 Infected/drainage surgical site(s), infection 5 2 Dehiscence 1 0 Diarrhea 1 3 Bloody stool 1 0 Hypersalivation 1 2 UTI 0 1 *Cats may have experienced more than one type or occurrence of an event during the study. The mean WBC count in the robenacoxib group was 13.8 ± 5.64 103/μL (ranging from 4.4- 36.8) and the mean WBC count in the control group was 12.7 ± 5.41 103/μL (with values ranging from 2.9 - 30.1) at the end of the study. There were 6 robenacoxib cases with elevated ALT post-treatment compared to 1 control case. There were 4 robenacoxib cases with elevated AST post-treatment compared to 1 control case. The most commonly reported adverse reactions in cats treated with robenacoxib were increased incision site bleeding, leukocytosis, fever, inappetence, infected incision sites, vomiting, and lethargy. The results of the field study demonstrate that robenacoxib injection, when administered for a maximum of 3 days, is well-tolerated for the control of postoperative pain associated with onychectomy, ovariohysterectomy, and castration in cats.

Occurrences of hepatopathy, ataxia, skin lesions/urticaria, and anaphylaxis have been associated with the use of ONSIOR. In a month-long pilot study, 3 dogs that received ONSIOR developed hepatic toxicity. Two of these dogs were euthanized and a third dog recovered after prolonged hospitalization and supportive therapy. In foreign market experience, elevated liver enzymes, hepatic necrosis and death have been associated with the long term use of robenacoxib in dogs. Occurrences of liver failure, hepatitis, and cholangiohepatitis have been reported. In two other field studies, bradycardia, 2nd degree heart block in four dogs, and ventricular arrhythmia in one dog were noted in anesthetized dogs treated with ONSIOR injection. Injection site reactions (edema, necrosis, and abscesses), and anaphylactic reactions (panting, drooling, shock, pallor, dyspnea, tachypnea, ataxia) have been associated with the use of ONSIOR injection.
