Effient is used with aspirin by patients with heart disease (recent heart attack, unstable angina) who undergo a certain heart procedure (angioplasty). This medication helps to prevent other serious heart/blood vessel problems (such as heart attacks, strokes, blood clots in stents). It works by blocking platelets from sticking together and prevents them from forming harmful blood clots. This "anti-platelet" effect helps to keep blood flowing smoothly in your body.

Pradaxa helps to prevent platelets in your blood from sticking together and forming a blood clot. pradaxa is used to prevent blood clots and to reduce the risk of stroke in people with a certain type of heart rhythm disorder. pradaxa is also used to treat or prevent blood clots in the veins of your legs (deep vein thrombosis, or DVT), or the veins in your lungs (pulmonary embolism, or PE).
