What is Primacor used for?

Primacor is used for the short term treatment of severe congestive heart failure. This is a condition where the heart fails to pump enough blood around the body. The symptoms of this condition include weakness, breathlessness, fluid build-up in the tissues and a blue discolouration of the skin.

Primacor also helps to maintain the output of blood from the heart in patients following heart surgery.

Primacor helps improve the efficiency with which your heart pumps blood around your body.

Primacor works by increasing the force by which your heart muscles work and opening up your blood vessels to allow blood to flow more freely.
