Information and Resources
Antiplatelet Medicines for Peripheral Arterial Disease
Examples
| Generic Name | Brand Name |

How It Works
Antiplatelets work in various ways to prevent blood clots.
Why It Is Used
These medicines may be used instead of aspirin (which is also an antiplatelet medicine) or after a person has had a procedure (such as bypass surgery, atherectomy, or angioplasty) performed on a blood vessel.
How Well It Works
These medicines can prevent the formation of blood clots in people who have peripheral arterial disease (PAD).1 Antiplatelet medicines may help lower the risk of heart attack and stroke in people who have PAD.
Side Effects
Some side effects of these antiplatelet medicines may include:
- Stomach irritation.
- Bleeding in the stomach or intestines.
- Allergic reaction.
- Increased bruising.
- Bleeding (hemorrhage) in the brain or other internal organs.
- Lowered numbers of blood cells.
See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
What To Think About
All antiplatelet medicines increase the risk of bleeding.
The best dosage and length of treatment with these medicines is still under study.
Clopidogrel may not work as well as it should in some people, because their bodies may not break down the drug properly. If your doctor thinks that your body is not using clopidogrel properly, he or she may give you a genetic test. This test checks to see if you have genes that let your body use clopidogrel. But experts aren't sure yet whether genetic changes keep clopidogrel from working. If you have concerns about the medicine, talk to your doctor. Do not stop taking clopidogrel unless your doctor tells you to.
