Background of Revatio

Revatio, which is the name for sildenafil, is mainly prescribed to treat pulmonary arterial hypertension (PAH). Pfizer, a pharmaceutical company, originally developed Revatio as an essential treatment option in the field of cardiovascular medicine.

Chemical Composition and Classification

Sildenafil, found in Revatio, falls under a group of medications called phosphodiesterase 5 (PDE5) inhibitors. It is classified based on its structure and the particular enzymatic pathway it affects in the body.


Primary Indications

Revatio is a medication that relaxes muscles of the blood vessels and increases blood flow to particular areas of the body 1It is used to treat pulmonary arterial hypertension (PAH) and improve exercise capacity in men and women 1Sildenafil under the name Viagra is used to treat erectile dysfunction (impotence) in men 1.

Revatio is also used to decrease the risks associated with high altitude pulmonary edema 1High-altitude pulmonary edema (HAPE) is a life-threatening non-cardiogenic pulmonary edema and the most common fatal manifestation of severe high-altitude illness 2. HAPE develops due to exposure to low oxygen levels at high altitudes. Environmental factors, such as cold air, can worsen your symptoms by causing increased stress on your lungs. Your risk for altitude illness may be greatest above 8,000 feet (about 2,500 meters) 3. 3Healthline 2UpToDate

How Revatio Differentiates from Similar Medications

Although PDE5 inhibitors are available, like tadalafil and vardenafil, Revatio distinguishes itself in several ways. It has received FDA approval specifically for treating PAH. Its longer half-life ensures prolonged effects. It has an established safety record based on years of clinical use.

How It Works

Mechanism of Action in the Body

Revatio functions by blocking the action of the PDE5 enzyme, which ultimately causes a rise in cyclic guanosine monophosphate (cGMP) levels in blood vessels found in the lungs. The increased cGMP levels prompt vasodilation, leading to a decrease in blood pressure.

Time to Onset and Duration of Effect

After being taken by mouth, Revatio reaches its levels in the blood within one hour. Its therapeutic effects start after and last for around 4 to 6 hours.

Off-label Use

Overview of Off-label Prescriptions

Although Revatio has not been officially approved for other uses, doctors have prescribed it for off-label uses based on real-world evidence and studies that highlight the advantages of using Revatio for purposes other than its main approved uses 1One example of off-label use is in treating high altitude pulmonary edema (HAPE) 23HAPE is a life-threatening non-cardiogenic pulmonary edema and the most common fatal manifestation of severe high-altitude illness 2.

Revatio’s effectiveness in treating other conditions is still being studied, and it is important to note that when considering off-label uses, a comprehensive assessment of risks versus benefits must be conducted using expertise as the guiding factor 1. 2: Healthline 3UpToDate
