Abstract

Angiotensin receptor blockers, such as telmisartan, are considered effective in the treatment of hypertension and proteinuria due to chronic kidney disease (CKD) in cats. It selectively blocks the AT₁ receptor and does not affect the ATâ‚‚ receptor, thus effectively blocking the activity of the renin angiotensin aldosterone system. This study aims to compare over time the changes in various indicators, including systemic hypertension and proteinuria, before and after the administration of telmisartan in cats with CKD. Decrease in blood pressure (BP) (p < 0.001) and urine protein to creatinine (UP/C) ratio (p < 0.001) were found to be statistically significant over time after the administration of telmisartan. BP and the UP/C ratio were 160 ± 22.2 and 0.50 ± 0.647 before telmisartan administration (Day 0), 150 ± 21.0 and 0.27 ± 0.487 on the 30th day (Day 30), 150 ± 17.0 and 0.25 ± 0.376 on the 60th day (Day 60), and 140 ± 17.8 and 0.15 ± 0.233 on the 90th day (Day 90) after administration, respectively. BP and UP/C were statistically significantly lower in cats with CKD over time at each time point from Day 0 to Day 90 at 30 day intervals. Especially after 90 days of telmisartan administration, the improvement of BP and UP/C were estimated to be about 20 mmHg and 0.35, respectively. In conclusion, the oral administration of telmisartan to cats with CKD is effective in improving BP and proteinuria, which has a positive effect on long-term survival in cats with CKD.
