Short overview of Revatio

Revatio, also known as sildenafil citrate, is a medication primarily used to treat pulmonary arterial hypertension (PAH). It belongs to a class of drugs called phosphodiesterase-5 inhibitors, which work by relaxing the blood vessels in the lungs to allow blood to flow more easily.

How does Revatio work?

Revatio works by inhibiting the enzyme phosphodiesterase-5 (PDE-5), which regulates blood flow in the lungs. By blocking this enzyme, Revatio helps to relax the smooth muscle cells in the blood vessels, leading to vasodilation and improved blood flow. This can reduce the symptoms of PAH and improve exercise capacity in patients with the condition.

What is PAH?

Pulmonary arterial hypertension (PAH) is a type of high blood pressure that affects the arteries in the lungs and the right side of the heart. It is a serious condition that can lead to shortness of breath, fatigue, chest pain, and other symptoms. PAH can be caused by various underlying conditions, such as connective tissue diseases, congenital heart defects, or exposure to certain drugs or toxins.

Who can benefit from Revatio?

Revatio is approved for the treatment of PAH in adults and children. It can help improve exercise capacity and delay clinical worsening in patients with the condition. In clinical trials, Revatio has been shown to significantly improve the ability to exercise and quality of life in patients with PAH.

Side effects of Revatio

Like all medications, Revatio can cause side effects in some people. Some common side effects may include headache, flushing, upset stomach, and nasal congestion. In rare cases, more serious side effects such as sudden vision loss or hearing loss may occur. It is important to discuss any potential side effects with your healthcare provider.


Revatio is an effective medication for the treatment of pulmonary arterial hypertension, helping patients improve their exercise capacity and quality of life. If you have been diagnosed with PAH, talk to your doctor about whether Revatio may be a suitable treatment option for you.
