Nitrolingual (Nitroglycerin SPRAY) 0.4mg/ 15.4ml

Nitrolingual is used to manage conditions related to cardiovascular health, particularly those involving angina pectoris. It is indicated for the following:

• Acute angina pectoris: Provides rapid relief of chest pain associated with angina attacks.
• Prophylaxis of angina attacks: Prevents angina attacks before activities that may trigger them, such as physical exertion or emotional stress.
• Acute heart failure: Helps manage acute left ventricular failure by reducing the workload on the heart.
• Coronary spasms: Relieves spasms in the coronary arteries during catheterization procedures.

• Nitroglycerin is bio-converted to nitric oxide, which causes vasodilation of veins and arteries. This reduces preload and afterload, decreasing myocardial oxygen demand and improving blood flow to the heart. The sublingual administration ensures rapid absorption and onset of action.

Nitrolingual may cause various side effects, ranging from common to serious. Common Side Effects:

• Headache: Often mild to moderate and transient.
• Dizziness: Due to the vasodilatory effects of the medication.
• Flushing: Redness or warmth in the face and neck.
• Nausea: Mild gastrointestinal discomfort.

Serious or Rare Side Effects

• Severe hypotension: Low blood pressure that may cause fainting or dizziness.
• Syncope: Temporary loss of consciousness due to reduced blood pressure.
• Methemoglobinemia: A condition where the blood cannot carry oxygen effectively.
• Allergic reactions: Rare but may include rash, itching, or swelling.

Nitrolingual should be used with caution and under medical supervision. Important precautions include:

• Avoid alcohol: Consuming alcohol may enhance the hypotensive effects.
• Monitor blood pressure: Regularly check blood pressure, especially when starting treatment.
• Avoid sudden position changes: May cause dizziness or fainting due to blood pressure drops.
• Inform healthcare provider: About all medications being taken to avoid interactions.
• Store below 25°C: Keep in the original pack, protect from moisture.

Nitrolingual may interact with other medications, leading to potentially harmful effects. Major Interactions (Avoid):

• Phosphodiesterase-5 inhibitors: Such as sildenafil, tadalaffil, or vardenafil, which can cause severe hypotension.
• Other nitrates: Concurrent use may lead to excessive vasodilation and hypotension.

Moderate Interactions (Monitor Closely)

• Calcium channel blockers: May enhance hypotensive effects.
• Beta-blockers: May reduce the effectiveness of Nitrolingual.
• Diuretics: May increase the risk of hypotension.
