Nitro Spray 400 mcg/spray contains Nitroglycerin, a fast-acting nitrate medication used for the rapid relief and prevention of angina pectoris (chest pain) caused by coronary artery disease. This convenient sublingual spray delivers a precise dose of nitroglycerin directly into the bloodstream through the lining of the mouth, providing quick onset of action during acute episodes of chest discomfort.

Angina occurs when the heart muscle does not receive enough oxygen-rich blood, typically due to narrowed coronary arteries. Nitro Spray works by relaxing and widening blood vessels, especially the veins and coronary arteries. This vasodilatory effect reduces the workload of the heart and improves oxygen supply to the heart muscle, helping to relieve chest pain quickly and effectively.

Each metered spray delivers 400 micrograms of nitroglycerin, ensuring accurate and consistent dosing. The spray formulation offers ease of use, portability, and rapid absorption, making it ideal for emergency situations or prior to activities that may trigger angina symptoms, such as physical exertion or emotional stress.

Indications

Nitro Spray 400 mcg/spray is indicated for:

• Rapid relief of acute angina attacks

• Short-term prevention of angina triggered by exercise or stress

• Management of chest pain associated with coronary artery disease

It is intended for adult patients under medical supervision and should always be used as prescribed by a healthcare professional.

Key Features

• Active Ingredient – Nitroglycerin: A well-established nitrate for rapid vasodilation and angina relief.
• Fast-Acting Sublingual Spray: Quick absorption through the oral mucosa ensures rapid onset of action.
• Precise Metered Dose: Each spray delivers 400 mcg for accurate administration.
• Portable and Convenient: Compact packaging allows easy carrying for emergency use.
• Proven Cardiovascular Support: Helps reduce cardiac workload and improve oxygen delivery to the heart.

Mechanism of Action

Nitroglycerin is converted in the body to nitric oxide, a natural vasodilator. Nitric oxide relaxes smooth muscle cells in blood vessel walls, leading to dilation of veins and arteries. Venous dilation reduces the amount of blood returning to the heart (preload), decreasing cardiac workload. Arterial dilation improves blood flow in the coronary arteries, enhancing oxygen supply to the heart muscle. Together, these effects relieve chest pain and improve overall cardiac efficiency during angina episodes.

Dosage and Administration

• Administer one spray under or onto the tongue at the onset of chest pain.

• Do not inhale the spray.

• If pain persists, additional sprays may be used at 5-minute intervals, as directed by a physician.

• Seek immediate medical attention if chest pain continues after the recommended doses.

• For prevention, use 5–10 minutes before activities known to trigger angina.

Patients should remain seated or lying down while using the spray to minimize the risk of dizziness or fainting.

Precautions and Safety Information

Common side effects may include headache, flushing, dizziness, or lightheadedness due to blood vessel dilation. These effects are usually temporary but should be discussed with a healthcare provider if persistent or severe.

Nitro Spray should not be used with phosphodiesterase-5 (PDE-5) inhibitors used for erectile dysfunction, as this combination may cause a dangerous drop in blood pressure. Inform your physician about all current medications and underlying medical conditions before starting therapy.

Store the spray at room temperature and keep the container tightly closed when not in use.
