Overview of Revatio – Description
Revatio is a prescription drug that contains the active ingredient sildenafil, which is also found in Viagra. It belongs to a class of medications known as phosphodiesterase type 5 inhibitors and is primarily used to treat pulmonary arterial hypertension (PAH).
What is Revatio?
Revatio is a pharmaceutical medication that contains sildenafil. Sildenafil is a potent phosphodiesterase type 5 (PDE5) inhibitor, which means it helps relax the blood vessels in the lungs to increase blood flow and decrease the strain on the heart.
Main Uses
Revatio is mainly prescribed for the treatment of pulmonary arterial hypertension (PAH) in adults. PAH is a condition characterized by high blood pressure in the arteries that supply the lungs, leading to shortness of breath, fatigue, and ultimately, heart failure. By dilating the blood vessels in the lungs, Revatio helps reduce the symptoms associated with PAH and improves the ability to exercise.
How Revatio Works
When sildenafil, the active ingredient in Revatio, enters the body, it selectively inhibits the enzyme phosphodiesterase type 5, which is responsible for breaking down a natural compound called cyclic guanosine monophosphate (cGMP). By preventing the breakdown of cGMP, sildenafil helps increase its levels, resulting in relaxation and dilatation of the pulmonary blood vessels.
Administration and Dosage
Revatio is available in tablet form and is typically taken orally three times a day, with or without food. The dosage prescribed by the healthcare professional may vary depending on the individual’s specific condition, response to treatment, and other factors. It is important to follow the prescribed dosage and administration instructions given by the healthcare provider.
Possible Side Effects
Like any medication, Revatio may cause side effects. Common side effects include headache, dizziness, flushing, indigestion, and nasal congestion. It’s crucial to consult a healthcare professional if these side effects persist or worsen. Additionally, in rare cases, Revatio can cause more serious side effects such as sudden vision loss or hearing impairment. If such symptoms occur, immediate medical attention is necessary.

2. Uses of Revatio
Revatio, a prescription medication containing sildenafil, is primarily used for the treatment of pulmonary arterial hypertension (PAH). PAH is a condition characterized by high blood pressure in the arteries of the lungs, leading to shortness of breath, dizziness, and fatigue.
Revatio works by relaxing and widening the blood vessels in the lungs, reducing the resistance to blood flow and improving exercise capacity in patients with PAH. It belongs to a class of drugs called phosphodiesterase type 5 inhibitors.
2.1 Treatment of Pulmonary Arterial Hypertension (PAH)
Revatio is the first FDA-approved oral therapy for the treatment of PAH. Clinical studies have shown that Revatio can improve exercise ability and delay the progression of PAH symptoms.
2.2 Off-label Use
In addition to its approved use for PAH, Revatio is sometimes prescribed off-label for other conditions like erectile dysfunction (ED). However, it’s important to note that Revatio is not equivalent to Viagra, as it contains a different dose of sildenafil and is specifically formulated for the treatment of PAH.
If you are seeking treatment for ED, it is recommended to discuss with your healthcare provider about alternative medications or therapies specifically indicated for that condition.
2.3 Pediatric Use
Revatio is also approved for the treatment of pediatric patients (aged 1 to 17 years) with PAH to improve exercise capacity. The dosing for pediatric patients differs from that of adult patients. It is crucial to consult with a pediatric specialist for proper dosage and administration.
2.4 Combination Therapy
Revatio may be used in combination with other PAH treatments, such as prostacyclin analogs, endothelin receptor antagonists, or calcium channel blockers, as recommended by a healthcare professional. The combination therapy aims to maximize the therapeutic effects and improve patient outcomes.
It’s important to note that the use of Revatio for any condition should be under the guidance of a qualified healthcare professional. Always follow the prescribed dosage and safety instructions provided by your healthcare provider.

Use of Revatio in Treating Pulmonary Arterial Hypertension (PAH)
Pulmonary arterial hypertension (PAH) is a condition characterized by high blood pressure in the arteries that supply the lungs. It can lead to symptoms such as shortness of breath, fatigue, chest pain, and fainting. PAH is a serious condition that requires appropriate and effective treatment.
Revatio, a prescription medication containing sildenafil as its active ingredient, has been approved by medical professionals for the treatment of PAH. Sildenafil belongs to a class of drugs known as phosphodiesterase type 5 inhibitors, which work by relaxing and widening the blood vessels, reducing the strain on the heart and improving blood flow to the lungs.
How does Revatio specifically help in treating PAH?
Revatio effectively targets the narrow blood vessels in the lungs, easing their constriction and reducing the resistance to blood flow. By improving blood circulation in the pulmonary arteries, Revatio helps to lower blood pressure and alleviate the symptoms associated with PAH.
Studies have shown that Revatio can significantly improve exercise capacity and delay the progression of PAH. It has been observed to enhance the ability to perform physical activities and improve overall quality of life for patients living with this condition.
How is Revatio typically prescribed for PAH?
The dosage and duration of Revatio treatment for PAH vary depending on individual factors such as age, severity of the condition, and response to the medication. It is important to follow the dosing instructions provided by a healthcare professional or specified on the prescription label.
Revatio is available in tablet form and is usually taken three times a day, with or without food. To ensure maximum effectiveness, it is recommended to take the medication at regular intervals. Missing a dose should be avoided, but if it happens, it should be taken as soon as possible unless it is close to the next scheduled dose.
| Age Group | Dosage |
|---|---|
| Adults | 20 mg tablet, three times a day |
| Children (1-17 years) | Dosage based on weight and determined by the healthcare professional |
It is crucial to take Revatio as prescribed and not to exceed the recommended dosage. Regular monitoring and follow-up with a healthcare provider are essential to assess the effectiveness of the medication and adjust the treatment plan accordingly.
Possible side effects and precautions
Like any medication, Revatio may cause side effects, although not everyone experiences them. Common side effects include headache, facial flushing, indigestion, dizziness, and nasal congestion. These side effects are usually mild and temporary.
However, if any severe or persistent side effects occur, it is important to seek medical attention immediately. This could include symptoms such as chest pain, vision changes, sudden hearing loss, or an erection lasting longer than four hours.
Prior to taking Revatio, it is essential to inform your healthcare provider of any existing medical conditions or medications you are currently taking. Certain medications and underlying health conditions may interact or be contraindicated with Revatio, posing potential risks and complications.
To gain a comprehensive understanding of Revatio, its uses, and related precautions, it is always advisable to consult reliable sources and medical professionals. For more information, refer to reputable websites such as the U.S. Food and Drug Administration (FDA) or consult your healthcare provider directly.
