Overview of Nitroglycerin Ointment

Nitroglycerin Ointment is a widely used topical medication for the management of chronic anal fissures and angina pectoris.

• Anal fissures are small tears in the lining of the anus, often caused by constipation, straining, or trauma. They are common among adults and especially frequent in women after pregnancy. Roughly 1 in 10 individuals experience an anal fissure at some point in their life.

• Angina, on the other hand, is chest pain or discomfort caused by reduced blood flow to the heart due to coronary artery disease (CAD). In the United States, nearly 10 million people suffer from angina each year, with stable angina affecting about 3–4% of adults over 20 years.

Both conditions can lead to serious health complications if left untreated. Nitroglycerin Ointment, belonging to the nitrate class of medicines, plays a vital role in relaxing blood vessels, reducing pain, and improving blood circulation under proper medical supervision.

Uses of Nitroglycerin Ointment

• Anal Fissures → Relieves pain, reduces anal sphincter spasm, and promotes faster healing.

• Angina Pectoris → Helps relax coronary blood vessels, improve blood flow, and ease chest pain.

Composition

• Active Ingredient: Nitroglycerin

• Category: Vasodilator (works by releasing nitric oxide to dilate blood vessels).

How to Apply Nitroglycerin Ointment

1. Clean and dry the affected area thoroughly.

2. Use gloves or an applicator to apply a small prescribed amount.

3. For anal fissures, apply directly to the anal area.

4. Wash hands properly after application.

Benefits of Nitroglycerin Ointment

• Relieves Pain – Provides quick comfort from anal fissure pain and angina discomfort.

• Improves Blood Circulation – Enhances healing by increasing blood flow to affected tissues.

• Reduces Muscle Spasms – Relaxes smooth muscles in blood vessels, reducing tension and strain.

Mechanism of Action

Nitroglycerin in the ointment releases nitric oxide (NO), which relaxes smooth muscles and dilates blood vessels. This leads to:

• Improved blood flow

• Reduced pain intensity

• Faster tissue repair and healing
