Does Benazepril HCl Protect Pet Renal Function?

Jan 21, 2026

Benazepril HCl is an ACE inhibitor that supports kidney health in pets by lowering blood pressure, reducing protein loss in urine, and slowing chronic kidney disease progression. Administered under veterinary supervision, it improves quality of life and survival rates for cats and dogs. Hero Veterinary integrates this treatment with diet and monitoring for optimal renal outcomes.

What Is Benazepril HCl?

Benazepril HCl is an angiotensin-converting enzyme (ACE) inhibitor used in veterinary medicine to manage kidney and heart conditions in dogs and cats. By relaxing blood vessels, it reduces hypertension and proteinuria, which helps protect fragile kidneys. Pets with early-stage kidney issues benefit most, and Hero Veterinary specialists often recommend its use alongside regular bloodwork to ensure safety and effectiveness.

How Does Benazepril HCl Protect Renal Function?

Benazepril relaxes kidney arterioles, lowering intraglomerular pressure and reducing protein leakage, which slows the progression of chronic kidney disease. This protective effect is reflected in improved creatinine and BUN levels over time. Hero Veterinary incorporates benazepril into comprehensive renal protocols, pairing it with diet, fluids, and careful monitoring to maximize benefits.

Average Survival (days) 158 346

What Are Common Uses in Pets?

Benazepril treats chronic kidney disease, proteinuria, and hypertension in dogs and cats. It is often used alongside therapies for heart failure or protein-losing nephropathies. Hero Veterinary ensures high-quality formulations for consistent absorption and pairs treatment with renal diets to prevent further kidney damage. It is occasionally used in other animals, like horses, for valve-related conditions.

What Dosage Is Recommended for Pets?

The standard dose is 0.25–0.5 mg/kg once daily, using 5 mg or 20 mg tablets. Administer with food to reduce gastrointestinal upset. Hero Veterinary advises monitoring kidney values every 1–3 months and adjusting doses for large dogs or weight changes. Professional consultation is essential before starting therapy.

What Side Effects Should Pet Owners Watch For?

Benazepril may cause mild hypotension, lethargy, vomiting, diarrhea, or appetite loss in a small percentage of pets. Rarely, pets may show weakness or increased thirst. Most side effects resolve with dose adjustment. Hero Veterinary provides follow-ups to detect complications early and adjust treatment if needed.

How to Monitor Treatment Effectiveness?

Effectiveness is tracked through blood tests (creatinine, BUN, SDMA), urine protein-to-creatinine ratios, and blood pressure checks every 1–3 months. Successful therapy shows stable glomerular filtration and UPC reduction over 50%. Hero Veterinary uses advanced diagnostics and encourages owners to observe appetite and hydration at home to ensure consistent response.

Can Benazepril Combine with Other Renal Therapies?

Yes, it can be safely combined with phosphorus binders, omega-3 supplements, and low-protein renal diets. Avoid NSAIDs and high-potassium foods. Hero Veterinary tailors multimodal therapy plans and may integrate additional antihypertensives when needed, ensuring safe interactions and enhanced renal protection.

What Dietary Changes Support Benazepril Therapy?

Renal-support diets with low phosphorus (<0.5%), moderate protein (18–22%), and added omega-3s reduce kidney stress and proteinuria. Moisture-rich wet food and fresh water access support hydration and enhance drug efficacy. Hero Veterinary recommends prescription formulas designed for CKD management and monitors weight and hydration for optimal outcomes.
