Persantine (Dipyridamole)

General Information

Persantine (Dipyridamole) is used in combination with ‘blood thinners’ like warfarin. It is to keep clots from forming after heart valve replacements. Clots are a serious complication that can cease heart attacks and strokes. It may also cause blocked blood vessels in the lungs or called pulmonary embolisms. The combination of medications lessens the chance of a clot forming on the valve.


How does Persantine (Dipyridamole) work?

Persantine (Dipyridamole) prevents blood cells called platelets from clumping together inside the blood vessels. It is sometimes referred to as a ‘blood thinner’ and dilates the blood vessels.

This drug works by blocking the action of an enzyme found in platelets called phosphodiesterase. Inside the platelets phosphodiesterase normally breaks down a chemical called cyclic AMP. Cyclic AMP plays a key role in blood clotting. If the level of cyclic AMP in the platelets is high this prevents the platelets from clumping together. This medication causes the levels of cyclic AMP in the platelets to rise because it stops phosphodiesterase from breaking it down. This means that this drug stops the platelets from clumping together and causing a blood clot.
