Revatio Uses

Revatio is approved for treating pulmonary arterial hypertension (PAH) in adults. It works by blocking a certain enzyme in the lungs, which causes the blood vessels in the lungs to stay relaxed to improve blood flow. Although there is no cure for PAH, using Revatio can improve a person's ability to exercise and delay serious complications, such as lung transplants and loss of life.

What Is Revatio Used For?

Revatio® (sildenafil citrate) is a prescription medication licensed to improve the ability to exercise and to slow down worsening conditions in people with pulmonary arterial hypertension (PAH).
Pulmonary arterial hypertension is high blood pressure in the vessels that carry blood to the lungs. These vessels are called the pulmonary arteries. When these arteries become too narrow or stiff, the heart has to work harder to pump blood through them. As the heart works harder, it begins to enlarge. Eventually heart failure may occur.
PAH is a serious condition that can cause life-threatening complications if left untreated. Unfortunately, there is no cure for PAH.
There are many causes of pulmonary arterial hypertension. Sometimes, the cause is not known. When the cause is known, it can be due to one of the following:
Early in the disease, some people may not have any symptoms at all. Others may have symptoms during times of physical activity or exercise. The early symptoms of PAH may include:
  • Shortness of breath during exercise or activity
  • Lack of energy
  • Tiredness.
As the disease progress, symptoms become more severe. These later symptoms may include:
  • Chest pain
  • Dizziness or fainting
  • Lightheadedness
  • Swelling of the lower legs, ankles, or feet.
Most of the symptoms of pulmonary arterial hypertension make it difficult to exercise or take part in physical activity. Revatio can reduce these symptoms and help improve the ability to exercise. It can also slow down worsening conditions that lead to negative outcomes of the disease, such as lung transplants, the need for additional medications, or even loss of life.
Currently, there is no cure for PAH. Treatment is usually aimed at the underlying cause, when a cause is known. In addition, treatment is used to relieve symptoms of the disease.
Treatment to improve symptoms may include the following:
  • Oxygen -- to treat shortness of breath
  • Diuretics (such as furosemide) -- to reduce fluid accumulation and swelling
  • Warfarin or other anticoagulant medications -- to reduce the risk of a blood clot
  • Digoxin -- to help the heart work more efficiently
  • Exercise -- to improve endurance.
Other treatment is used to dilate or expand the pulmonary arteries, making it easier for the heart to pump blood through them. Revatio falls under this type of treatment. Other medications that help to open up the blood vessels in the lungs include:
