What is the action of dipyridamole?

Dipyridamole appears to act in vivo by synergistically modifying several biochemical pathways, including: a) inhibition of platelet cAMP-phosphodiesterase; b) potentiation of adenosine inhibition of platelet function by blocking reuptake by vascular and blood cells, and subsequent degradation of adenosine; and possibly …

Is enoxaparin an anticoagulant?

warfarin dipyridamole Using dipyridamole together with warfarin can cause you to bleed more easily. You may need a dose adjustment in addition to testing of your prothrombin time or International Normalized Ratio (INR).

Is aspirin an anticoagulant?

“The primary effect of aspirin as an anticoagulant is thought to involve platelet function; however, aspirin is also an anti-inflammatory,” said Kenneth Mann, PhD, a professor from the department of biochemistry at the University of Vermont. Less clear are other methods by which aspirin acts as an anticoagulant.

Is Lovenox a LMWH?

Who needs dual antiplatelet therapy?

Dual-antiplatelet therapy should be administered for at least 12 months in patients with first-generation drug-eluting stents (DESs) and 6 months in those with second-generation DESs because earlier discontinuation is associated with a high risk of stent thrombosis.

Is Aggrenox and Plavix the same?

Plavix (clopidogrel) is a cheap, generically available blood thinner that protects you from clots after you’ve had a heart attack or surgery. Prevents blood clots that can cause a stroke.
