Periovulatory administration of therapeutic and supratherapeutic doses of firocoxib does not impair induced ovulation or follicular dynamics in mares treated with a GnRH analogue

This study evaluated whether the administration of therapeutic and supratherapeutic doses of firocoxib during the periovulatory period affects ovulation or follicular dynamics in mares.

Study Overview

• Objective: To determine if firocoxib—a selective COX-2 inhibitor—impairs the ovulation process or preovulatory follicular development when administered to mares induced to ovulate with a GnRH analogue.
• Methodology: Seventy cycling mares were randomly assigned to one of three groups:
  • Firocoxib at 0.1 mg/kg (therapeutic dose).
  • Firocoxib at 0.3 mg/kg (supratherapeutic dose).
  • An untreated control group.
• Protocol: Treatments were administered intravenously on Day 0 (day of GnRH induction) and Day 1. Ovarian structures were monitored via transrectal ultrasonography from Day 0 through Day 4.

Key Findings

• Ovulation Integrity: All mares in all groups ovulated within 72 hours of induction. No instances of ovulatory failure or hemorrhagic anovulatory follicles were reported.
• Follicular Dynamics: There were no significant differences among the groups regarding dominant follicle diameter or the rate of follicular growth between Day 0 and Day 1.
• Safety Conclusion: Periovulatory administration of firocoxib, even at doses higher than the therapeutic recommendation, did not impair induced ovulation or follicular development.

Clinical Implications

Unlike non-selective NSAIDs—which have been shown to potentially block ovulation in mares—the high selectivity of firocoxib for the COX-2 enzyme appears to preserve essential physiological functions, such as ovulation. These findings suggest that firocoxib can be safely used during periovulatory reproductive management protocols in mares without negatively impacting ovulatory timing or follicular health.

  • Group I (GI): Flunixin meglumine (1.1 mg/kg).
  • Group II (GII): Firocoxib (0.1 mg/kg).
  • Group III (GIII): Meloxicam (0.6 mg/kg).
• Evaluations: Researchers assessed clinical, behavioral, and hematological parameters, along with peritoneal fluid (PF) analysis, before surgery and at 1, 2, 3, 5, and 7 days post-castration.

Key Findings

• Pain and Inflammation Control: All three drugs were found to be effective in controlling pain; none of the study animals required analgesic rescue.
• Clinical Observations: Horses in the FX and MX groups exhibited higher incidences of pelvic limb rigidity and significant prepuce edema compared to the FM group. Tachycardia was observed in the FX and MX groups, and hyperthermia was noted specifically in the MX group.
• Laboratory Results: All groups showed increases in leukocytes, neutrophils, monocytes, and fibrinogen levels following surgery, consistent with the expected inflammatory response to surgical trauma.
• Peritoneal Fluid: Surgery triggered an abdominal inflammatory process in all groups, evidenced by changes in the color and turbidity of the peritoneal fluid and increased protein concentration. While PF markers fluctuated, the FM group showed a faster return to normal color compared to the FX and MX groups.

Conclusions

The study concluded that while FM, FX, and MX are equally effective at controlling pain and inflammation after castration, flunixin meglumine (FM) provided more advantageous results regarding the control of local edema and body temperature.
