Nitro-Dur functions primarily as a prophylactic intervention, not intended for immediate relief of acute angina attacks but rather for the prevention of these episodes through continuous administration of nitroglycerin. This medication belongs to the class of drugs known as nitrates which help by dilating blood vessels and increasing blood flow to the heart muscle, thus reducing its workload and oxygen demand

The centerpiece of Nitro-Dur therapy is nitroglycerin, a potent vasodilator. The main mechanism of action involves relaxation of vascular smooth muscles, which results in dilation of peripheral veins and coronary arteries. This dilation reduces myocardial oxygen consumption and helps prevent the onset of chest pain associated with angina, particularly in situations where the heart’s demand for oxygen exceeds the supply.

Nitro-Dur is an essential component in the spectrum of cardiac treatment modalities, specifically designed to prevent episodes of angina pectoris (chest pain). By utilizing a controlled release of nitroglycerin through a transdermal patch, Nitro-Dur delivers consistent and sustained medication absorption directly through the skin into the bloodstream, ensuring prolonged therapeutic effects. This method of delivery is particularly beneficial for patients seeking a convenient and efficient way to manage angina symptoms, thus improving their quality of life and supporting their long-term cardiac health.

Additional information



● Prevention of Angina Pectoris: Nitro-Dur is extensively prescribed to prevent angina pectoris. It does not provide immediate relief from acute angina attacks but is used as part of a comprehensive preventative cardiac care program.

Patient Guidelines

● Patients prescribed with Nitro-Dur should adhere to the following usage guidelines:

● Start using Nitro-Dur patches as instructed by a healthcare provider, usually one patch applied each day.

● Apply the patch on a clean, dry, and hairless area of skin, preferably on the upper body or upper arm.

● Remove the patch after 12-14 hours to allow a nitrate-free interval of 10-12 hours each day, typically during nighttime. This regimen helps prevent the development of tolerance to nitrates.

● Rotate patch application sites daily to avoid skin irritation.

Safety Precautions

● Pregnancy and Lactation: Consultation with a healthcare provider is crucial as the effects of nitroglycerin on unborn babies or nursing infants are not well-established.

● Hypotension: Patients with low blood pressure should use Nitro-Dur cautiously, as further reduction in blood pressure may occur leading to possible complications.
