Nitro SR Tablet 2.6 mg contains Nitroglycerin, a long-acting nitrate used for the prevention of angina pectoris (chest pain) associated with coronary artery disease. The “SR” (Sustained Release) formulation is specially designed to release the medication gradually over an extended period, ensuring continuous therapeutic effect and long-lasting protection against angina episodes.

Angina develops when the heart muscle does not receive sufficient oxygen due to narrowed or blocked coronary arteries. Nitro SR Tablet helps prevent these episodes by relaxing and widening blood vessels, thereby improving blood flow and reducing the workload on the heart. Unlike fast-acting sublingual forms of nitroglycerin used for immediate relief, the sustained-release tablet is intended for regular use to reduce the frequency and severity of angina attacks.

Each tablet contains 2.6 mg of nitroglycerin in a controlled-release matrix. After oral administration, the medication is slowly absorbed, maintaining steady blood levels throughout the dosing interval. This makes Nitro SR Tablet 2.6 mg suitable for patients who require ongoing angina prophylaxis under medical supervision.

Indications

Nitro SR Tablet 2.6 mg is indicated for:

• Long-term prevention of chronic stable angina

• Reduction in the frequency of angina attacks

• Adjunct therapy in coronary artery disease

It is not intended for the rapid relief of acute chest pain. Patients experiencing sudden angina should use a fast-acting nitrate as prescribed by their physician.

Key Features

• Active Ingredient – Nitroglycerin: A well-established vasodilator used in cardiovascular care.
• Sustained-Release Formula: Provides prolonged anti-anginal effect through gradual drug release.
• Prevention-Focused Therapy: Reduces the occurrence of chest pain episodes with regular use.
• Improves Cardiac Efficiency: Decreases heart workload and enhances coronary blood flow.
• Convenient Oral Dosage: Easy-to-administer tablet for routine daily therapy.

Mechanism of Action

Nitroglycerin works by converting to nitric oxide in the body. Nitric oxide relaxes vascular smooth muscle, leading to dilation of veins and arteries. Venous dilation reduces the volume of blood returning to the heart (preload), thereby decreasing cardiac workload and oxygen demand. Arterial dilation improves blood supply to the myocardium (heart muscle). These combined effects help prevent oxygen imbalance that triggers angina.

The sustained-release design ensures that therapeutic levels of nitroglycerin are maintained over time, helping to protect against predictable episodes of chest pain, particularly during daily activities.

Dosage and Administration

• Take the tablet exactly as prescribed by your physician.

• Swallow the tablet whole with water; do not crush or chew.

• It is usually taken on an empty stomach for optimal absorption, unless otherwise directed.

• Follow a nitrate-free interval schedule if advised, to prevent tolerance.

Regular follow-up is important to monitor blood pressure and treatment response.

Precautions and Safety Information

Common side effects may include headache, flushing, dizziness, or low blood pressure due to vasodilation. Patients should rise slowly from sitting or lying positions to reduce the risk of lightheadedness.

Nitro SR Tablet must not be used together with phosphodiesterase-5 (PDE-5) inhibitors, as this combination can cause severe hypotension. Inform your healthcare provider about all current medications and underlying health conditions.

Store in a cool, dry place away from direct sunlight and moisture.
