Effects of trometamol ketorolac eye drops on blood count, serum biochemistry, and urinalysis in healthy dogs

Abstract

ABSTRACT This study aimed to evaluate whether the use of trometamol ketorolac for 30 consecutive days may change the blood count, the serum biochemistry profile, and the urinalysis of healthy dogs. Eleven small breed dogs (4.6-10kg), with ages ranging from 1 to 9 years were enrolled in the study. Dogs received 40μL of 0.4% trometamol ketorolac eye drops, every 12 h in both eyes for 30 consecutive days. Blood and urine samples were collected at baseline, and following 15 and 30 days of the beginning of the treatment. Creatinine levels increased significantly at day 15 (1.21±0.1mg/dL) and 30 (1.22±0.1mg/dL) when compared with baseline (0.94±0.1mg/dL) (P0.05). From observations of our study, it can be concluded that the instillation of trometamol ketorolac for 30 consecutive days did not cause clinically relevant changes in the blood count, biochemistry profile and in the urinalysis of healthy dogs.
