Description
💊🛡️ Aspirin 75mg + Clopidogrel 75mg Capsule: Dual Antiplatelet Therapy for Heart and Stroke Protection
Aspirin 75mg + Clopidogrel 75mg is a widely used dual antiplatelet medication prescribed to reduce the risk of heart attacks, strokes, and other cardiovascular events. This fixed-dose combination works by preventing the formation of blood clots in arteries, especially in patients with coronary artery disease (CAD), acute coronary syndrome (ACS), or those who have undergone angioplasty with stent placement.
Together, these two drugs target different pathways of platelet activation, offering stronger and synergistic protection against arterial thrombosis compared to monotherapy.
🔬 Mechanism of Action
🔹 Aspirin (75mg)
Aspirin irreversibly inhibits cyclooxygenase-1 (COX-1) enzyme, leading to a reduction in thromboxane A2, a chemical that promotes platelet aggregation and vasoconstriction. This action prevents platelets from sticking together and forming clots.
🔹 Clopidogrel (75mg)
Clopidogrel is a prodrug that is converted in the liver to its active form. It selectively and irreversibly blocks the P2Y12 ADP receptor on the platelet surface, preventing ADP-mediated platelet activation and aggregation.
✅ Combined effect: By blocking two different platelet activation pathways, the combination offers enhanced protection from arterial clot formation—the main cause of heart attacks and ischemic strokes.
📌 Indications and Uses
This combination is prescribed for the prevention of thrombotic cardiovascular events in high-risk patients:
-
Acute Coronary Syndrome (ACS): including unstable angina, NSTEMI, STEMI
-
Post-percutaneous coronary intervention (PCI): with or without stent placement
-
Chronic stable angina or CAD
-
Ischemic stroke or Transient Ischemic Attack (TIA)
-
Peripheral arterial disease (PAD)
-
Secondary prevention of cardiovascular or cerebrovascular events
💊 Dosage and Administration
-
Standard dose: One capsule daily, with or without food
-
Taken at the same time every day to maintain steady blood levels
-
Usually prescribed for 12 months post-ACS or PCI, and sometimes continued longer in high-risk patients as per cardiologist’s advice
-
Not to be stopped abruptly without medical consultation
⚠️ Precautions and Warnings
-
Contraindicated in:
-
Active bleeding disorders
-
Peptic ulcer disease
-
Hemorrhagic stroke
-
Hypersensitivity to salicylates or clopidogrel
-
-
Use with caution in:
-
Elderly patients
-
Kidney or liver impairment
-
Asthma, especially if aspirin-sensitive
-
Monitor regularly for:
-
Signs of bleeding
-
Hemoglobin and platelet count
-
Liver function if prolonged use
🤒 Side Effects
Common:
-
Gastric irritation, acidity, or ulcers (aspirin-related)
-
Easy bruising, minor bleeding
-
Headache, dizziness
Serious (but rare):

Seek immediate care if symptoms like black/tarry stools, vomiting blood, or unusual bleeding appear.
🔄 Drug Interactions
-
Avoid with:
-
NSAIDs (increased bleeding risk)
-
Warfarin or other anticoagulants
-
Certain SSRIs, proton pump inhibitors (PPIs) like omeprazole (may reduce clopidogrel effectiveness)

Keep out of reach of children
📝 Conclusion
Aspirin 75mg + Clopidogrel 75mg capsule is a cornerstone in the secondary prevention of cardiovascular and cerebrovascular events. Its dual antiplatelet action significantly reduces the risk of heart attacks and strokes, especially after cardiac procedures. When taken regularly under medical supervision, it offers life-saving protection against arterial thrombosis.
