Drug Class: Dual Antiplatelet Combination | Form: Oral Tablet | Prescription Status: Prescription Only (Rx) — DRAP Registered
What is Noclot-EA 75/75mg Tablet? Noclot-EA 75/75mg contains Clopidogrel 75mg and Aspirin 75mg — a fixed-dose dual antiplatelet combination targeting platelet aggregation through two completely different and complementary mechanisms simultaneously. This dual antiplatelet therapy (DAPT) is specifically indicated for patients with acute coronary syndrome — including unstable angina, non-ST elevation myocardial infarction, and ST elevation myocardial infarction — and patients undergoing coronary stent placement where preventing dangerous in-stent thrombosis is critically important. Clinical trials have conclusively demonstrated that DAPT with Clopidogrel and Aspirin produces significantly superior protection against cardiovascular death, heart attack, and stroke compared to Aspirin alone in high-risk coronary patients. The fixed-dose combination simplifies the dual antiplatelet regimen into a single daily tablet — improving compliance which is the most critical factor in preventing life-threatening stent thrombosis. Stopping this medicine suddenly without cardiologist advice can be fatal.
What is Noclot-EA 75/75mg Used For?
- Acute coronary syndrome — unstable angina, NSTEMI, and STEMI management (شدید دل کی بیماری میں خون کے لوتھڑے کی روک تھام)
- Post-coronary stent placement — keeping stents open after angioplasty procedure (اسٹینٹ کے بعد خون کے لوتھڑے کی روک تھام)
- Secondary prevention of heart attack — long-term protection in established coronary artery disease (دوبارہ دل کے دورے کی روک تھام)
- Secondary prevention of ischaemic stroke and TIA — protection after transient ischaemic attack (فالج کی دوبارہ روک تھام)
- Peripheral artery disease — reducing cardiovascular event risk in patients with blocked leg arteries
- Atrial fibrillation — stroke prevention in selected patients under cardiologist supervision
How Does it Work? Clopidogrel 75mg irreversibly blocks P2Y12 ADP receptors on platelet surfaces — preventing ADP-mediated platelet activation and aggregation for the entire 7 to 10-day lifespan of each affected platelet. Since platelets cannot synthesise new receptors, this inhibition is permanent until new platelets are produced. Aspirin 75mg irreversibly inhibits COX-1 enzyme in platelets — permanently blocking thromboxane A2 production that normally triggers platelet clumping. By simultaneously blocking two completely independent platelet activation pathways — ADP receptor signalling through Clopidogrel and thromboxane A2 synthesis through Aspirin — Noclot-EA produces markedly stronger antiplatelet protection than either medicine alone, significantly reducing the risk of arterial thrombus formation in high-risk coronary patients.
Dosage and Administration
⚠️ Never stop without explicit cardiologist advice — stopping DAPT after coronary stent placement triggers life-threatening in-stent thrombosis within hours. Always take with food to reduce gastrointestinal irritation from Aspirin component. Never combine with other NSAIDs regularly — greatly increases bleeding risk. Carry emergency card informing healthcare providers of dual antiplatelet therapy.

Who Should NOT Take Noclot-EA 75/75mg?
- Active bleeding — stomach ulcer, intracranial bleeding, or any active significant bleeding source
- Allergy to Clopidogrel, Aspirin, Salicylates, or any NSAID
- Severe liver disease — impaired Clopidogrel activation through hepatic CYP enzymes
- Severe kidney impairment — use with caution; increased bleeding risk
- Aspirin-sensitive asthma — Aspirin-induced bronchospasm
- Haemophilia or other significant hereditary bleeding disorders
- Third trimester of pregnancy — strictly contraindicated
- Children and adolescents under 18 years — Aspirin risk of Reye's syndrome
- Currently taking Methotrexate above 15mg weekly
- Severe uncontrolled hypertension — bleeding risk significantly elevated
Side Effects
Common: Easy bruising and longer bleeding from minor cuts — expected antiplatelet effect (چھوٹی چوٹ سے زیادہ خون آنا — متوقع اثر), mild stomach discomfort and heartburn from Aspirin component — reduced by taking with food, mild nausea, mild headache.
Serious — Stop and seek emergency help immediately: Gastrointestinal bleeding — dark tarry stools or vomiting blood (پیٹ سے خون — فوری ہسپتال جائیں), signs of intracranial bleeding — sudden severe headache with vomiting and confusion (فوری ہسپتال جائیں), Thrombotic Thrombocytopaenic Purpura — TTP; fever with neurological symptoms and bruising — rare but life-threatening (فوری ہسپتال جائیں), severe allergic reaction — sudden widespread rash, swelling of face or throat, difficulty breathing (فوری مدد لیں), Aspirin-induced bronchospasm — sudden severe wheezing in sensitive patients (فوری مدد لیں), significant unexplained bruising or prolonged bleeding from minor wounds suggesting excessive antiplatelet effect, signs of haemorrhagic stroke — sudden severe headache, vision loss, one-sided weakness (فوری ہسپتال جائیں).
Drug Interactions
| Medicine | Interaction |
|---|---|
| Omeprazole / Esomeprazole | Significantly reduce Clopidogrel conversion to active form through CYP2C19 inhibition — reduces antiplatelet effectiveness; use Pantoprazole or Rabeprazole as preferred PPI with Clopidogrel |
| Warfarin / other anticoagulants | Greatly increased bleeding risk with dual antiplatelet — triple therapy requires strict specialist supervision and regular INR monitoring |
| NSAIDs (Ibuprofen, Diclofenac) | Ibuprofen may compete with Aspirin for COX-1 binding reducing cardioprotection — significantly increased gastrointestinal bleeding with both NSAID components |
| SSRIs (Fluoxetine, Sertraline) | Increased gastrointestinal bleeding risk with dual antiplatelet combination |
| Methotrexate | Aspirin increases Methotrexate toxicity — avoid above 15mg weekly Methotrexate |
| Fluconazole / Fluvoxamine | CYP2C19 inhibitors reduce Clopidogrel activation — reduced antiplatelet effectiveness |
| Antidiabetic medicines | Aspirin may enhance hypoglycaemic effect — monitor blood glucose in diabetic patients |
| Uricosuric agents (Probenecid) | Aspirin even at low dose reduces uric acid excretion — may worsen gout |
| Alcohol (شراب) | Significantly increases gastrointestinal bleeding risk from both components — avoid completely |

FAQs
Q: Can Noclot-EA 75/75mg ever be stopped if I feel completely well after my heart attack or stent procedure? Never stop without explicit cardiologist advice — feeling well does not mean stent protection is no longer needed. Stopping DAPT prematurely after coronary stent placement triggers in-stent thrombosis — a catastrophic clot forming inside the stent causing sudden complete coronary artery blockage, massive heart attack, and potentially death within hours. Your cardiologist will determine the safest duration based on your stent type, individual bleeding risk, and cardiovascular risk profile.
Q: Which PPI is safest to take with Noclot-EA for stomach protection? Omeprazole and Esomeprazole significantly inhibit the CYP2C19 enzyme responsible for converting Clopidogrel to its active antiplatelet form — reducing Clopidogrel effectiveness by up to 40%. Pantoprazole and Rabeprazole have significantly less CYP2C19 inhibition and are the preferred gastroprotective choices for patients requiring stomach protection alongside Clopidogrel-containing dual antiplatelet therapy. Always inform your cardiologist of all medicines you are taking including stomach acid medicines.
Q: What should I do if I need surgery or a dental procedure while taking Noclot-EA? Never stop Noclot-EA without consulting your cardiologist first — stopping DAPT for any procedure must be carefully planned balancing bleeding risk against catastrophic stent thrombosis risk. Your cardiologist and the surgeon or dentist must communicate and jointly decide whether to continue, temporarily stop, or bridge with alternative antiplatelet therapy. Most minor dental procedures can be performed safely without stopping antiplatelet medicines — never make this decision independently.
