About Revatio
Revatio is a prescription-only medication approved in Australia for the treatment of pulmonary arterial hypertension (PAH). Containing the active ingredient sildenafil, it belongs to the phosphodiesterase-5 (PDE5) inhibitor class and works by relaxing the blood vessels of the lungs, allowing blood to flow more easily and reducing the heart’s workload. Although sildenafil is widely recognised for treating erectile dysfunction, the Revatio formulation is specifically licensed for cardiovascular conditions, with the typical tablet strength of 20 mg. It provides a targeted therapy for patients whose lungs cannot adequately oxygenate the blood, helping to improve exercise capacity and delay disease progression.
What is Revatio?
Revatio is the branded version of sildenafil designed for pulmonary arterial hypertension. Approved by the Therapeutic Goods Administration (TGA) in 2006, it is supplied as 20 mg oral tablets that must be prescribed by a qualified health professional. As a PDE5 inhibitor, Revatio is part of a well-established drug class used to modulate vascular tone. The product is manufactured by Pfizer, a global pharmaceutical company with a long history of cardiovascular research. In Australia, Revatio is listed on the Pharmaceutical Benefits Scheme (PBS) for eligible patients, reflecting its recognised therapeutic value for PAH.
How Revatio Works
Revatio blocks the enzyme phosphodiesterase-5, which normally breaks down cyclic guanosine monophosphate (cGMP) in smooth-muscle cells. By inhibiting PDE5, the drug allows cGMP to accumulate, leading to prolonged relaxation of pulmonary arterial smooth muscle. This vasodilation lowers pulmonary vascular resistance and improves blood flow through the lungs. The effect begins within 30-60 minutes after ingestion, with a half-life of roughly 4 hours, allowing once- or twice-daily dosing depending on disease severity. Sildenafil is metabolised primarily by the liver enzyme CYP3A4 and excreted in the urine, so drug interactions that affect this pathway can alter Revatio’s plasma levels.
Why Revatio is Used for Heart & Circulation Conditions
- Improves Exercise Capacity - By reducing pulmonary artery pressure, patients can walk farther and perform daily activities with less breathlessness. Clinical trials show a median increase of 30-40 metres in the 6-minute walk test.
- Delays Disease Progression - Lower vascular resistance eases the right ventricle’s workload, slowing right-heart failure development, which is a leading cause of mortality in PAH.
- First-Line Therapy in PAH - Australian and international guidelines (e.g., ESC/ERS) list PDE5 inhibitors as initial oral therapy for patients with mild-to-moderate disease.
- Combination Therapy Compatibility - Revatio can be combined with endothelin receptor antagonists (e.g., bosentan) or prostacyclin analogues, offering a synergistic approach for high-risk patients.
- Evidence-Based Dosing - Studies support 20 mg three times daily for most adults, with adjustments based on tolerance and response, providing a flexible regimen that matches individual needs.
Off-Label and Investigational Uses of Revatio
While Revatio is formally approved only for PAH, the underlying sildenafil molecule has been investigated for several other cardiovascular conditions. Small-scale trials have explored its use in right-heart failure secondary to congenital heart disease, chronic thromboembolic pulmonary hypertension, and high-altitude pulmonary edema. These studies suggest modest hemodynamic benefits, but the evidence remains limited and the TGA has not extended approval beyond PAH. Off-label use should only be considered under the supervision of a qualified healthcare provider, and patients must be fully informed of the experimental nature of such treatment.
Is Revatio Right for You?
Revatio is appropriate for adults diagnosed with pulmonary arterial hypertension who require vasodilatory therapy to improve functional status. Ideal candidates are individuals with WHO functional class II-III symptoms, stable liver function, and no contraindications such as concurrent nitrate therapy. Patients with severe renal impairment may need dose reduction, while those with severe hepatic dysfunction should avoid the drug altogether. Pregnant or breastfeeding women are generally advised against use because safety data are lacking. As always, the prescribing clinician will weigh the benefits against potential risks, taking into account comorbidities such as hypertension, coronary artery disease, or visual disorders.
Taking Revatio Effectively
- Timing: Take the 20 mg tablet with a glass of water, preferably at the same times each day to maintain steady plasma concentrations. Some clinicians recommend doses in the morning, midday, and early evening to avoid nighttime hypotension.
- Food Interactions: A high-fat meal can delay absorption, but overall exposure is unchanged; meals are not contraindicated but consistent timing helps predict effects.
- Alcohol: Moderate alcohol intake is permissible, but excessive consumption may amplify vasodilatory effects, leading to dizziness or low blood pressure.
- Missed Dose: If a dose is forgotten and the scheduled time is within 4 hours, take it promptly. Skip it if more than 4 hours have passed and resume the regular schedule; do not double up.
- Travel: For long trips, keep tablets in original packaging with a copy of the prescription. Consider using a temperature-stable container if climate conditions are extreme.
Understanding Side Effects and How to Manage Them
Most adverse events stem from the vasodilatory action of sildenafil. Common side effects include headache, flushing, dyspepsia, and nasal congestion-these result from systemic blood-vessel relaxation. Simple measures such as staying hydrated, using over-the-counter antacids for indigestion, or applying a cold compress for flushing can alleviate discomfort. Visual disturbances (e.g., blurred vision or a blue tint) occur in a minority of patients due to PDE6 inhibition in the retina; these are usually transient and resolve without intervention. Rare but serious reactions-such as sudden vision loss, hearing impairment, or severe hypotension-require immediate medical attention. Patients should be instructed to seek help if they experience chest pain, fainting, or persistent visual changes.

Frequently Asked Questions
-
How quickly will I notice improvement after starting Revatio? Most patients report a reduction in breathlessness within a few weeks, but optimal benefits often become evident after 8-12 weeks of consistent therapy.
-
Can I take Revatio if I am already on a nitrate medication? No. Combining PDE5 inhibitors with nitrates can cause dangerous drops in blood pressure and is contraindicated.
-
Is it safe to use Revatio while traveling to high-altitude locations? Sildenafil may help prevent high-altitude pulmonary edema, but it should only be used under medical guidance and not as a substitute for proper acclimatization.
-
What should I do if I miss a dose while on a twice-daily schedule? Take the missed tablet as soon as you remember if it is within four hours of the scheduled time; otherwise, skip it and continue with your regular dosing times.
-
Are there any dietary restrictions while on Revatio? Grapefruit juice can inhibit CYP3A4 metabolism, potentially increasing sildenafil levels. It is advisable to limit or avoid grapefruit products.
-
How does Revatio compare with other PAH therapies like bosentan? Revatio targets the nitric oxide pathway, whereas bosentan blocks endothelin receptors. Both have proven efficacy; clinicians often select one based on patient tolerance, side-effect profile, and potential drug interactions.
-
Can Revatio be used in children with PAH? The drug is not approved for pediatric use in Australia, and dosing data in children are limited. Treatment in this population should be managed with specialist paediatric PAH medications.
-
Will Revatio affect my ability to drive or operate machinery? Some patients experience dizziness or visual changes, especially when first starting therapy. Until you know how the medication affects you, avoid activities that require full alertness.
-
Is Revatio covered by private health insurance? Coverage varies by insurer and policy. Many patients rely on the PBS subsidy; checking your specific plan’s formulary is recommended.
-
What monitoring is required while taking Revatio? Regular follow-up appointments to assess exercise capacity, echocardiography, and liver function tests are standard to ensure the drug remains safe and effective.
-
Can I switch from generic sildenafil for erectile dysfunction to Revatio for PAH? Although both contain sildenafil, Revatio is formulated and dosed specifically for PAH. Switching should only occur under physician direction, with appropriate dose adjustments.
