Study Notes
Oral Antiplatelet Drugs
- Examples: aspirin, clopidogrel
- Mechanism of Action: Inhibit platelet aggregation in the arteries, preventing thrombus formation
- Aspirin and clopidogrel block different platelet activation pathways.
- Low-dose aspirin (80 mg/day) is typically used for antiplatelet effects.
Nursing Considerations for Oral Antiplatelet Drugs
- Assess history of intracranial hemorrhage, upper GI bleeding, peptic ulcer disease, or known bleeding tendencies.
- Monitor for and report increased bruising, petechiae, purpura, and apparent or occult bleeding.
- Do not administer concurrently with warfarin.
Intravenous Antiplatelet Drugs
- Examples: abciximab, eptifibatide, tirofiban
- Mechanism of Action: Block the final common pathway of platelet activation, making them more effective than oral antiplatelet drugs.
- Increased risk of bleeding compared to oral antiplatelet drugs.
Nursing Considerations for Intravenous Antiplatelet Drugs
- Determine history of bleeding disorders, intracranial hemorrhage, or recent trauma or surgery.
- Inquire about recent use of oral antiplatelet or anticoagulant drugs.
- Monitor CBC, including hemoglobin, hematocrit, and platelet count, and clotting studies.
- Monitor vital signs and ECG during therapy.
- Maintain separate IV lines for blood draws and administration of other drugs during infusion.
- Closely observe for and immediately report anaphylaxis or bleeding uncontrolled by pressure.
- Keep resuscitation equipment readily available.
- Maintain bedrest during infusion.
