Ames, M. K., Atkins, C. E., Lee, S., Lantis, A. C., & zumBrunnen, J. R. (2015, November 30). American Journal of Veterinary Research.

By: M. Ames*, C. Atkins*, S. Lee, A. Lantis* & J. zumBrunnen

MeSH headings : Aldosterone / blood; Aldosterone / urine; Angiotensin-Converting Enzyme Inhibitors / administration & dosage; Animals; Benzazepines / administration & dosage; Blood Pressure / drug effects; Body Weight / drug effects; Dogs / physiology; Enalapril / administration & dosage; Female; Furosemide / administration & dosage; Heart Rate / drug effects; Male; Peptidyl-Dipeptidase A / blood; Renin-Angiotensin System / drug effects; Time Factors
topics (OpenAlex): Hormonal Regulation and Hypertension; Renin-Angiotensin System Studies; Heart Failure Treatment and Management
TL;DR: Administration of high doses of enalapril and benazepril significantly inhibited ACE activity, yet did not prevent increases in mean urine and serum aldosterone concentrations resulting from furosemide activation of RAAS, suggesting that ald testosterone breakthrough from ACE inhibition was a dose-independent effect of ACE inhibitors.

The effect of enalapril on furosemide‐activated renin–angiotensin–aldosterone system in healthy dogs

Lantis, A. C., Ames, M. K., Werre, S., & Atkins, C. E. (2015, March 15). Journal of Veterinary Pharmacology and Therapeutics.

By: A. Lantis*, M. Ames n, S. Werre * & C. Atkins n

MeSH headings : Aldosterone / urine; Angiotensin-Converting Enzyme Inhibitors / pharmacology; Animals; Blood Pressure / drug effects; Creatinine / urine; Diuretics / pharmacology; Dogs; Drug Interactions; Enalapril / pharmacology; Furosemide / pharmacology; Heart Rate / drug effects; Peptidyl-Dipeptidase A / blood; Renin-Angiotensin System / drug effects
topics (OpenAlex): Renin-Angiotensin System Studies; Receptor Mechanisms and Signaling; Heart Failure Treatment and Management
TL;DR: It appears that failure to suppress aldosterone suppression with furosemide stimulation may be a drug class effect, and the discrepancy between the current data and the documented benefits of enalapril likely reflects the efficacy of this ACE inhibitor in suppressing tissue RAAS, variable population responsiveness to ACE-inhibition, and/or providing additional survival benefits, possibly through as yet unknown mechanisms.

TL;DR: Benazepril decreased plasma ACE activity but did not prevent furosemide-induced RAAS activation, indicating aldosterone breakthrough (escape), particularly noteworthy in that breakthrough is observed at the time of initiation of RAAS suppression, as opposed to developing after months of therapy.
