Loprin 75 mg — Heart Protection, Stroke Prevention Pakistan

What Is Loprin 75?

Loprin is Highnoon Laboratories' brand name for low-dose aspirin (75 mg). It is an enteric-coated tablet — it does not dissolve in the stomach, but in the intestines, reducing stomach irritation.

What Is Loprin 75 Used For?

1. Heart Attack Prevention (Secondary)

To prevent future events in patients who have already had a heart attack.

2. Stroke Prevention (Secondary)

In patients with a previous ischaemic stroke or TIA (mini-stroke).

3. Coronary Artery Disease

In patients with confirmed CAD or angina.

4. After Stent Placement

Loprin is taken lifelong after a heart stent (alongside Plavix for the first year).

5. After Bypass Surgery

After CABG (coronary artery bypass graft).

6. Atrial Fibrillation (Some Cases)

When anticoagulation is needed but Warfarin cannot be used.

7. High-Risk Diabetic Patients

With multiple risk factors (high BP, high cholesterol, smoking history).

8. Pre-Eclampsia Prevention

In high-risk pregnancies, started from 12+ weeks.

Dosage

Who Should Take Loprin? (Secondary Prevention)

Definite indications:

• Previous heart attack (MI)
• Previous ischaemic stroke or TIA
• Confirmed coronary artery disease
• Stent placement (PCI)
• Coronary bypass surgery (CABG)
• Peripheral artery disease (PAD)

Primary Prevention — NOT Routinely Recommended

If there has been no prior cardiac event, Loprin is not routinely recommended — the bleeding risk may outweigh the benefit. Many people in Pakistan start Loprin on their own — this is wrong.

Discuss with your doctor if:

• Age 50+ with multiple risk factors (diabetes + high BP + high cholesterol + smoking)
• Strong family history of early heart disease
• 10-year cardiovascular risk > 20%
• Low personal bleeding risk

Side Effects

Common:

• Mild bleeding (cuts bleed longer)
• Stomach upset (reduced with enteric coating)
• Easy bruising
• Heartburn

Serious:

• GI bleeding — the biggest concern (1–2% per year)
• Haemorrhagic stroke — rare
• Severe allergic reaction
• Tinnitus (at high doses)

Bleeding Warning Signs — See Doctor Immediately

• Vomiting blood
• Black tarry stools
• Uncontrolled nosebleed
• Blood in urine
• Sudden severe headache (intracranial bleed)
• Purple bruising on skin without injury

When to Avoid Loprin

• Active bleeding (anywhere)
• Active stomach ulcer
• Bleeding disorders (haemophilia)
• Severe asthma (NSAID-sensitive)
• Aspirin allergy
• Children under 16 (Reye's syndrome)
• Third trimester of pregnancy (full dose)
• Severe liver or kidney disease

Before Surgery

Stop Loprin 5–7 days before elective surgery. In emergency surgery, the doctor will decide.

After stent placement, never stop aspirin without consulting a cardiologist — the risk of clot formation is very high.

Drug Interactions

• Warfarin, DOACs: Significantly increased bleeding risk
• NSAIDs (Brufen, Voltral): Doubles stomach ulcer risk; reduces aspirin's antiplatelet effect
• SSRIs (antidepressants): GI bleeding risk
• Steroids: Increased bleeding risk
• Methotrexate: Toxicity
• ACE inhibitors: Reduced blood pressure control
• Alcohol: Stomach bleeding

Stomach Protection

Adding a PPI (Risek 20, Pantop) is common practice for long-term Loprin users when risk factors are present:

• Age 60+
• Previous GI bleed
• Taking NSAIDs or steroids simultaneously
• H. pylori positive

Aspirin Resistance

In 5–10% of patients, aspirin is not effective — known as "aspirin resistance". A cardiologist can arrange a platelet function test. The alternative is Plavix (clopidogrel).

Dental Procedures

Continue Loprin for routine dental work (extractions, cleanings) — the bleeding is manageable. Only stop for major surgery.

Brands in Pakistan

• Loprin (Highnoon)
• Aspart 75/150
• Cardiprin 100
• Disprin CV
• Generic low-dose aspirin

Conclusion

Loprin 75 (low-dose aspirin) is life-saving for heart attack and stroke survivors and patients with coronary artery disease. However, it is not routinely recommended for healthy individuals — the bleeding risk outweighs the benefit. Take after food, stop 5–7 days before surgery, and see a doctor for any GI bleeding signs.
