Semintra is indicated for the treatment of hypertension (high blood pressure) in cats. It may also be prescribed for cats with protein-losing nephropathy (kidney disease causing protein loss in urine). This is a veterinary-specific formulation not intended for human use.
Semintra contains telmisartan, an angiotensin II receptor blocker (ARB). It works by blocking angiotensin II receptors in blood vessels, preventing the hormone from causing vasoconstriction. This results in relaxation and widening of blood vessels, reducing blood pressure and decreasing strain on the heart and kidneys.
Semintra is a prescription-only veterinary medication formulated specifically for cats. Dosage is weight-based and administered orally, typically once daily. Side effects may include mild gastrointestinal upset. It should not be used in pregnant animals. Regular blood pressure monitoring and veterinary check-ups are recommended during treatment.
