🩸 Anticoagulants & Antiplatelet Drugs - Nursing Notes 🩸

1. What are they?

  • Anticoagulants = prevent clots from forming or growing (affect clotting factors)

  • Antiplatelets = stop platelets from sticking together (affect platelet aggregation)


πŸ§ͺ Anticoagulants (Blood Thinners)

Common Drugs:

  • Heparin (IV/Subcut) – fast-acting

  • Enoxaparin (Clexane) – Low Molecular Weight Heparin

  • Warfarin (Coumadin) – oral, long-term

  • DOACs (Direct Oral Anticoagulants) – e.g., apixaban, rivaroxaban, dabigatran

πŸ”₯ Mnemonic for Heparin & Warfarin Differences:

"HEP WAR"

  • Heparin = Emergency, PTT monitoring

  • Warfarin = Along-term, RINR monitoring


🩹 Monitoring Anticoagulants:

  • Heparin β†’ monitor aPTT (activated Partial Thromboplastin Time)

  • Warfarin β†’ monitor INR (International Normalized Ratio)

    • Target INR: usually 2–3

  • Antidotes:

    • Heparin β†’ Protamine sulfate

    • Warfarin β†’ Vitamin K


πŸ§ͺ Antiplatelet Drugs

Common Drugs:

  • Aspirin – inhibits thromboxane A2 (irreversible)

  • Clopidogrel (Plavix) – blocks ADP receptors on platelets

  • Ticagrelor, Prasugrel – newer ADP inhibitors

πŸ”₯ Mnemonic for Antiplatelet Drugs:

"A Cool Plate"

  • Aspirin

  • Clopidogrel

  • Prasugrel

  • (Plate = think Platelet)


🚨 Nursing Considerations

  • Watch for bleeding: gums, urine, stool, bruising, petechiae

  • Fall precautions (↑ risk of bleeding)

  • Soft toothbrush & electric razor

  • Avoid high-risk sports or activities

  • Check labs (aPTT, INR, platelet count)

  • Teach patient: No NSAIDs unless doctor-approved (↑ bleeding risk)


🧠 Quick Recap Mnemonic: "CLOTT"

  • Check labs (INR, aPTT)

  • Look for bleeding signs

  • Oral hygiene: soft toothbrush

  • Teach about safety

  • Tell doctor if unusual bleeding happens
