The objective of the study was to investigate the safety of a combination tablet of benazepril and pimobendan, Fortekor PLUS ® , in a randomized, blinded, parallel‐group design study in healthy adult beagle dogs. The test article, Fortekor PLUS ® tablets, was administered orally twice daily for 6 months at one, two, and four times the highest recommended dosage of 0.5 mg/kg benazepril hydrochloride/0.25 mg/kg pimobendan (four males and four females per group). An additional control group was sham‐dosed. Fortekor PLUS ® did not induce any treatment‐related effects on body weight, food consumption, neurological, ophthalmologic or physical assessments over the 6‐month treatment period. The test article was possibly associated with an increased frequency of occasional vomiting. Fortekor PLUS ® was associated with small, but significant, increases in heart rate and reductions in PR and QT intervals, which were assessed by electrocardiography. These effects were most probably related to reflex tachycardia secondary to reduced systemic blood pressure. Statistically significant changes in some clinical pathology variables were noted after test article administration, but were considered to be of no clinical relevance as values remained within reference ranges and/or were not dose‐dependent. No treatment‐related macroscopic or microscopic findings were observed. In conclusion, Fortekor PLUS ® tablets were well tolerated in healthy adult dogs when administered at one, two, and four times the highest recommended dosage for 6 months.
