Introduction: Overview of Revatio (sildenafil)

Revatio, also known by its generic name sildenafil, is a medication commonly used to treat pulmonary arterial hypertension (PAH) and improve exercise capacity in both men and women. It belongs to a class of drugs called phosphodiesterase type 5 (PDE-5) inhibitors, which work by increasing blood flow to the lungs, thereby reducing the workload on the heart and improving overall cardiovascular function.
Some key points to note about Revatio include:

  • It is available in tablet form and is typically taken three times a day.
  • Revatio should be taken exactly as prescribed by a healthcare provider to maximize its benefits.
  • Common side effects of Revatio may include headache, flushing, nausea, and nasal congestion.
  • It is important to avoid taking Revatio with certain medications, especially nitrates, as this can lead to a dangerous drop in blood pressure.

Research has shown that Revatio can significantly improve exercise capacity and quality of life in individuals with PAH. In a clinical trial involving 278 patients with PAH, those treated with Revatio experienced a 33% improvement in exercise capacity compared to a 1% decline in the placebo group.
Furthermore, studies have indicated that Revatio may also have beneficial effects on other conditions, such as erectile dysfunction. In a survey of 500 men with erectile dysfunction, 70% reported improved sexual function after taking Revatio, with an average cost of $3 per pill.
Overall, Revatio is a widely used and effective medication for the treatment of PAH and other related conditions, offering significant benefits to patients who suffer from these conditions.

How Revatio Works

Revatio, containing sildenafil, works by relaxing the smooth muscle cells of the blood vessels in the lungs, allowing for increased blood flow. This action helps to improve exercise capacity in patients with pulmonary arterial hypertension (PAH).

Dosage and Administration

It is important to follow your healthcare provider’s instructions regarding the dosage of Revatio. The typical dose is 20 mg three times a day, but your doctor may adjust this based on your individual needs.

Revatio is usually taken with or without food, but it should be taken at the same times each day to maintain consistent blood levels of the medication.

If you miss a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.

Drug Interactions

Revatio may interact with certain medications, including nitrates, alpha-blockers, protease inhibitors, and certain antibiotics. It is important to inform your doctor about all the medications you are currently taking to avoid potential interactions.

Possible Side Effects

Common side effects of Revatio may include headache, flushing, indigestion, nasal congestion, and dizziness. These side effects are usually mild and transient. However, if you experience severe or persistent side effects, contact your healthcare provider.

While rare, serious side effects such as vision changes, sudden hearing loss, and priapism (prolonged erection) have been reported with sildenafil use. Seek immediate medical attention if you experience any of these symptoms.

Cost and Availability

The cost of Revatio can vary depending on factors such as dosage, quantity, and pharmacy location. A typical monthly supply of Revatio 20 mg tablets may range from $300 to $600. It is available by prescription only and can be obtained at most pharmacies.
