Sep 25, 2025

Nitroglycerin tablet (marketed as NITROQUICK 6.4) is an essential medication for patients dealing with heart conditions, particularly angina (chest pain). Nitroglycerin controlled release tablets like NITROQUICK 6.4 are designed to provide long-lasting relief from chest pain by improving blood flow to the heart. If you're looking for a reliable treatment to manage your heart health, this medication might be a crucial part of your therapy plan. In this article, we'll explore the uses, dosage, benefits, and potential side effects of nitroglycerin tablets, as well as why you should consider choosing Steris Healthcare for your medication needs.

What is Nitroglycerin Tablet (NITROQUICK 6.4)?

Nitroglycerin tablet, specifically in the controlled release form like NITROQUICK 6.4 mg, is a well-known medication used to treat angina (chest pain) and other heart-related conditions. Nitroglycerin works by relaxing and widening the blood vessels, which improves blood flow to the heart. This reduces the workload on the heart, helping to prevent or relieve the pain associated with angina.

Unlike standard nitroglycerin tablets, nitroglycerin controlled release tablets like NITROQUICK 6.4 mg offer a sustained release of the active ingredient, ensuring long-lasting effects over an extended period. This feature allows the medication to provide continuous support to patients, helping to manage chronic angina effectively.

Nitroglycerin Tablet Uses

Nitroglycerin tablet is commonly used for several heart-related conditions, including:

  • Angina Pectoris (Chest Pain): The primary use of nitroglycerin tablet is to relieve chest pain caused by insufficient blood flow to the heart. By dilating blood vessels, nitroglycerin eases the pressure on the heart, reducing pain and discomfort.

  • Preventing Angina Attacks: When taken regularly, nitroglycerin controlled release tablets can help prevent angina attacks, allowing patients to go about their daily activities without worrying about sudden chest pain.

  • Acute Coronary Syndrome (ACS): In certain cases, nitroglycerin may be prescribed to manage acute coronary syndrome, which involves a range of conditions associated with reduced blood flow to the heart.

How Nitroglycerin Tablet Works

The active ingredient in nitroglycerin tablet is a nitrate compound. Nitroglycerin works by increasing the amount of nitric oxide in the blood vessels, which helps dilate them, improving circulation. This process:

  • Reduces the oxygen demand of the heart: By widening the blood vessels, the heart doesn’t have to work as hard to pump blood, which can relieve the symptoms of angina.

  • Improves blood flow: By expanding the blood vessels, nitroglycerin allows more blood (and oxygen) to reach the heart, helping to prevent or reduce chest pain.

Because of its controlled release formulation, NITROQUICK 6.4 mg ensures that the body receives a steady supply of the medication, minimizing the risk of sudden chest pain or discomfort throughout the day.

Dosage and Administration of Nitroglycerin SR (6.4 mg)

The typical dosage of nitroglycerin 6.4 mg is one tablet taken once or twice daily, depending on your healthcare provider’s recommendations. The nitroglycerin dose may be adjusted based on the severity of your condition and how your body responds to the treatment.

Important tips for taking nitroglycerin tablets:

  • Take it as prescribed: Always follow the dosage instructions given by your doctor. Do not take more than the prescribed dose to avoid potential side effects.

  • Swallow the tablet whole: Do not crush or chew the tablet, as this can interfere with the controlled release mechanism.

  • Timing is key: To ensure continuous relief, take the tablet at the same time each day as part of your heart health routine.

  • Monitor your symptoms: If you notice any side effects or changes in your condition, contact your healthcare provider immediately.

Nitroglycerin Side Effects

While nitroglycerin 6.4 mg is generally safe when used as prescribed, it can cause side effects in some people. Common side effects include:

  • Headache: A frequent side effect of nitroglycerin is a headache, which occurs due to the widening of blood vessels.

  • Dizziness or lightheadedness: Nitroglycerin can cause a drop in blood pressure, leading to dizziness, especially when standing up quickly.

  • Flushing or redness of the skin: Some people may experience skin flushing as a result of the blood vessels dilating.

  • Nausea: A small percentage of people may feel nauseous while taking this medication.

Serious side effects are rare but can occur, including severe allergic reactions or a significant drop in blood pressure. If you experience any unusual symptoms, it’s important to consult your doctor immediately.
