Captopril is used to treat minor to severe heart failure and high blood pressure. It lowers blood pressure, lowers the stress on the heart, and reduces fluid build-up in the lungs. It is often used in conjunction with other drugs.
It is best to give this drug on an empty stomach. If stopping use of this drug, consult your veterinarian for an effective gradual reduction in dosage.
Captopril inhibits the angiotensin converting enzyme (ACE), an enzyme that converts angiotensin I to angiotensin II. Angiotensin II acts as a potent vasoconstrictor, meaning it narrows the blood vessels. By inhibiting this enzyme, it prevents the angiotensin II from ever being created and relaxes the blood vessels. This lowers the blood pressure and reduces the amount of work the heart has to do.
Store in a tightly sealed container at room temperature.
If you miss a dose, give the dose as soon as possible. If it is almost time for the next dose, skip the missed dose, and continue with the regular schedule. Do not give your pet two doses at once.
