Nitroglycerine SR 6.4 mg

Cardiovascular diseases remain one of the leading causes of morbidity and mortality in India. Among these, angina pectoris (chest pain due to reduced blood flow to the heart) is a common and serious condition that significantly affects daily life and overall well-being. Effective long-term management is essential to prevent complications such as heart attack and heart failure.

NITROQUICK 6.4, formulated with Nitroglycerin Sustained Release (SR) 6.4 mg, is a well-established medication used for the prevention and long-term management of angina. Its sustained-release formulation ensures prolonged therapeutic action, helping patients maintain stable heart function and improved quality of life.

This in-depth blog covers everything you need to know about NITROQUICK 6.4, including its composition, mechanism of action, clinical uses, benefits, dosage guidelines, side effects, precautions, drug interactions, and its role in modern cardiac care.

Understanding Angina and Coronary Artery Disease

Angina pectoris is chest pain or discomfort that occurs when the heart muscle does not receive enough oxygen-rich blood. It is usually caused by coronary artery disease (CAD), where plaque buildup narrows or blocks the coronary arteries.

Common Symptoms of Angina

• Chest tightness, pressure, or pain

• Pain radiating to the left arm, neck, jaw, or back

• Shortness of breath

• Fatigue

• Sweating or dizziness

Angina is often triggered by physical exertion, emotional stress, cold weather, or heavy meals. If not managed properly, it may progress to a heart attack.

Introduction to NITROQUICK 6.4

NITROQUICK 6.4 is a prescription medicine containing Nitroglycerin SR 6.4 mg, designed for long-term prevention of angina attacks. Nitroglycerin is a nitrate that has been used for decades in cardiology due to its rapid and reliable effect on blood vessels.

The sustained-release (SR) formulation in NITROQUICK 6.4 allows the medicine to release gradually over time, ensuring continuous protection against chest pain throughout the day.

It is commonly prescribed by cardiologists and physicians across India as part of comprehensive heart disease management.

Composition of NITROQUICK 6.4

• Active Ingredient: Nitroglycerin

• Strength: 6.4 mg

• Dosage Form: Sustained Release Oral Tablet

Each tablet is carefully formulated to provide prolonged action while minimizing fluctuations in drug levels.

What is Nitroglycerin?

Nitroglycerin is a nitrate vasodilator that works by relaxing blood vessels, thereby improving blood flow to the heart muscle. It has been a cornerstone in the treatment of angina and other ischemic heart conditions for many years.

Nitroglycerin does not cure coronary artery disease but helps control symptoms and reduce the frequency and severity of angina attacks.

How NITROQUICK 6.4 Works (Mechanism of Action)

NITROQUICK 6.4 works through a well-defined cardiovascular mechanism:

• Converts into nitric oxide in the body

• Relaxes smooth muscles in blood vessel walls

• Causes dilation of veins and arteries

• Reduces workload on the heart

• Improves oxygen supply to the heart muscle

By lowering the heart’s oxygen demand and increasing blood flow, NITROQUICK 6.4 helps prevent angina episodes.

Sustained Release Advantage of NITROQUICK 6.4

The sustained-release formulation offers several benefits:

• Provides prolonged and consistent drug release

• Reduces the need for frequent dosing

• Maintains stable blood nitrate levels
