How it works
CoumadinAspirinPradaxaLovenoxHeparinXareltoEliquis
Coumadin (warfarin) prevents blood clots from forming. It doesn't break up clots that already exist. It can only stop new ones from forming or old ones from getting bigger.Aspirin is a salicylate and non-steroidal anti-inflammatory drug (NSAID). It blocks the inflammation process in your body, which relieves swelling and pain. It also prevents blood platelets from forming clots, which thins your blood.Pradaxa (Dabigatran) is an anticoagulant that stops the formation of blood clots.Lovenox (Enoxaparin) is an anticoagulant that prevents certain blood-clotting proteins from working. By stopping blood clots from forming, there's a lower chance of having a stroke or blood clots travel to your lungs.Heparin is an anticoagulant that binds with proteins and platelets to stop blood clots from being made and traveling to the brain, heart, and lungs.Xarelto (rivaroxaban) is an anticoagulant that stops blood clots from forming.Eliquis (apixaban) is a factor Xa inhibitor anticoagulant that stops the formation of blood clots in your body so you're less likely to have a stroke or heart attack.
