Losartan Potassium Tablet
Losartan potassium is an oral blood pressure medication (angiotensin receptor blocker) occasionally prescribed off-label for dogs or cats with hypertension, especially due to kidney disease. It helps relax blood vessels to lower blood pressure, similar to how enalapril or telmisartan are used in vet medicine, and is used under close veterinary guidance.
The uses and pharmacology described below reflect the FDA-approved labeling for this active ingredient; your veterinarian determines whether and how they apply to your animal's treatment plan.
Losartan potassium is an angiotensin II receptor antagonist utilized in veterinary medicine for cardiovascular and renal management. It is a prescription medication available for use in dogs and cats, frequently considered by veterinarians for patients presented with protein-losing nephropathy or high blood pressure. Your veterinarian will determine appropriateness based on blood work results and clinical status.
Prescription only. Use only under the direction of a licensed veterinarian. This information is not a substitute for veterinary diagnosis, prescribing or monitoring. Compounded drugs are not approved by the FDA for safety or effectiveness.
At a pharmacological level, it is considered for its role in managing the binding of angiotensin II to its receptors, providing a method for influencing vascular resistance and protein loss through the kidneys. Commonly observed effects include localized digestive changes such as vomiting or diarrhea and behavioral shifts like lethargy. Because it influences the renin-angiotensin-aldosterone system, your veterinarian will monitor for observational signs of low blood pressure or kidney stress through regular blood tests. Owners should monitor for significant shifts in thirst or energy and contact their veterinarian promptly.

Veterinarians discuss losartan in the context of kidney disease because it is considered to influence the pressure inside the kidneys and protein loss in the urine. Your veterinarian will determine if this approach is appropriate for your pet.
Your veterinarian will recommend periodic blood work to monitor kidney values and potassium levels. This monitoring ensures the management approach remains safe and suitable for your pet's renal status.
Losartan is often used in combination with other heart or blood pressure medications. Your veterinarian will determine the most appropriate protocol and monitor for observational signs of cumulative cardiovascular effects.
