Antiplatelets

Cardiovascular

Mark this drug class

Examples

aspirinclopidogrel

Prefix / Suffix: No consistent suffix

Physiology

Platelets clump together to form clots. Antiplatelets prevent this aggregation, reducing clot formation in arteries.

Mechanism of Action

They inhibit platelet activation and aggregation, preventing clot formation.

Indications

Myocardial infarction prevention
Stroke prevention
Post-stent placement

Side Effects / Adverse Effects

Bleeding (reduced clot formation)
GI irritation (especially aspirin)
Bruising

Contraindications

Active bleeding
Peptic ulcer disease
Bleeding disorders

Nursing Considerations

Monitor for signs of bleeding — gums, urine, stool (early detection prevents complications)
Hold before surgery (reduces bleeding risk during procedures)
Do not give aspirin to children (risk of Reye's syndrome)
Assess for GI discomfort or bleeding (common with aspirin use)
Ensure adherence after stent placement (prevents stent thrombosis — a high-risk complication)
