Similar to pimobendan + benazepril. Enalapril is another ACE inhibitor that reduces cardiac workload. Often used interchangeably with benazepril depending on vet preference.
Why are these prescribed together?
Enalapril, like benazepril, blocks the renin-angiotensin-aldosterone system to reduce fluid retention and lower blood pressure. Combined with pimobendan's heart-strengthening effects, this provides comprehensive heart failure management.
How they interact
No direct conflict. Same complementary mechanism as pimobendan + benazepril. The main difference between enalapril and benazepril is that enalapril is exclusively cleared by the kidneys, while benazepril has dual liver/kidney clearance. Benazepril may be preferred in dogs with kidney disease.
Dosing and timing tips
Enalapril: typically twice daily, can be given with or without food. Pimobendan: twice daily on empty stomach. Can be given at the same time as long as pimobendan is on an empty stomach.
Monitoring needed
Kidney values (BUN, creatinine) - especially important with enalapril since it's entirely kidney-cleared. Blood pressure monitoring. Watch for appetite changes.
Important warnings
If kidney values rise significantly, your vet may switch from enalapril to benazepril
Do not stop abruptly
Report lethargy, weakness, or loss of appetite

Other drug interactions
Pimobendan (Vetmedin) & Furosemide (Lasix)
The most common combination for dogs in congestive heart failure. Pimobendan strengthens the heart while furosemide removes excess fluid from the lungs.
Pimobendan (Vetmedin) & Benazepril
A standard combination for managing heart failure. Pimobendan strengthens the heart while benazepril (an ACE inhibitor) reduces cardiac workload by relaxing blood vessels.
Pimobendan (Vetmedin) & Sotalol
Used together when a dog has both weakened heart muscle and dangerous arrhythmias. Common in Dobermans with DCM. Sotalol controls heart rhythm while pimobendan supports heart function.
Pimobendan (Vetmedin) & Spironolactone
Spironolactone is often added to the treatment regimen for MMVD dogs in heart failure. It provides mild diuretic effects while protecting against harmful cardiac remodeling.
Important:Never start, stop, or adjust your dog's medication without consulting your veterinarian. The dosages and protocols described here are general references - your vet will determine the right approach for your dog based on their individual condition, weight, and overall health.
