It belongs to the phosphodiesterase-5 (PDE-5) inhibitor class, which is primarily used to treat pulmonary arterial hypertension (PAH). The drug improves blood flow in the lungs, reducing the workload on the heart and helping patients achieve better exercise capacity. Revatio is also recognized for its role in certain secondary vascular conditions, although its approved indication focuses on PAH. ## Quick Reference Facts ``` **Active Ingredient** : Sildenafil Citrate **Form** : pill 20 mg **Primary Uses** : Pulmonary arterial hypertension (PAH) ``` ## What is Revatio? Revatio is a generic formulation of sildenafil citrate, the same compound marketed under well-known brand names such as Viagra and Revatio. As a generic product, it contains the identical active molecule and meets bioequivalence standards set by health regulators, ensuring the same therapeutic effect as the branded versions. The medication is manufactured by several licensed pharmaceutical companies that adhere to Good Manufacturing Practice (GMP) guidelines. It is categorized as a PDE-5 inhibitor and is approved by major regulatory agencies for the treatment of PAH in adult patients. ## How Revatio Works Sildenafil citrate inhibits the enzyme phosphodiesterase-5, which normally degrades cyclic guanosine monophosphate (cGMP) in smooth-muscle cells. By blocking PDE-5, Revatio allows cGMP to accumulate, leading to relaxation of pulmonary arterial smooth muscle and dilation of the blood vessels in the lungs. This vasodilation reduces pulmonary vascular resistance, lowers the pressure the right side of the heart must generate, and consequently improves oxygen delivery during activity. The onset of action typically occurs within 30-60 minutes, with peak effects around 1-2 hours, and the drug’s half-life is approximately 4 hours, supporting a three-times-daily dosing schedule for PAH. ## Conditions Treated with Revatio - **Pulmonary Arterial Hypertension (PAH)** - Revatio relaxes pulmonary arteries, decreasing pulmonary arterial pressure and improving exercise capacity in patients with PAH. - **Chronic Thromboembolic Pulmonary Hypertension (CTEPH)** - In selected cases, PDE-5 inhibition helps alleviate residual vascular obstruction after surgical or interventional therapy. - **Right-Heart Failure Secondary to PAH** - By lowering afterload on the right ventricle, Revatio can contribute to better right-heart function, although it is not a standalone treatment for heart failure. ## Is Revatio the Right Medication for You? Revatio is appropriate for adult patients diagnosed with PAH who require long-term vasodilator therapy. It is especially beneficial for individuals who remain symptomatic despite optimal background treatment, such as endothelin-receptor antagonists or prostacyclin analogues. The drug is unsuitable for patients with a known hypersensitivity to sildenafil or any PDE-5 inhibitor, those using nitrates (e.g., nitroglycerin) because of dangerous hypotension, and patients with severe uncontrolled hypertension or recent major cardiovascular events. Physicians will usually assess baseline liver and kidney function before initiating therapy, as dose adjustments may be needed in hepatic or renal impairment. ## Buying Revatio from [our online pharmacy](https://liabilis.com/order-revatio-online-en.html) ### Why Choose Our Service?

Dosage may be adjusted based on tolerability and clinical response. - **Missed Dose** - If a dose is missed and the next scheduled dose is more than 4 hours away, take the missed dose. If the next dose is sooner, skip the missed one and resume the regular schedule. Do not double-dose. - **Overdose** - Symptoms of overdose may include severe headache, dizziness, visual disturbances, or a sudden drop in blood pressure. Seek immediate medical attention or contact a poison control center. - **Administration Tips** - Revatio can be taken with or without food. Avoid excessive alcohol, as it may enhance hypotensive effects. Caution is advised when operating machinery or driving until you know how the medication affects you. ## Safety Information ### ⚠️ Who Should Not Take Revatio - Known allergy to sildenafil citrate or any PDE-5 inhibitor. - Concurrent use of organic nitrates or nitric oxide donors. - Uncontrolled severe hypertension (systolic > 180 mm Hg or diastolic > 110 mm Hg). - Recent (within 30 days) major cardiovascular events such as myocardial infarction or stroke. - Severe hepatic impairment (Child-Pugh class C) or end-stage renal disease not on dialysis. ### Common Side Effects - Headache (most frequent, usually mild). - Flushing or warmth in the face and neck. - Dyspepsia or indigestion. - Nasal congestion. - Visual changes (e.g., color tinge, blurred vision) - typically transient. These effects are generally self-limiting; dose reduction or administration with food may improve tolerability. ### Serious Side Effects (Seek Immediate Medical Help) - Sudden loss of vision in one or both eyes (possible non-arteritic anterior ischemic optic neuropathy). - Sudden hearing loss or ringing in the ears. - Prolonged, painful erection lasting > 4 hours (iap). - Severe hypotension causing fainting or syncope. - Chest pain or new onset arrhythmias. If any of these occur, discontinue Revatio and obtain emergency medical care. ### Drug & Food Interactions - **Nitrates** (e.g., nitroglycerin, isosorbide dinitrate): additive vasodilation → life-threatening hypotension. - **Alpha-blockers** (e.g., prazosin, doxazosin): may cause symptomatic hypotension; monitor blood pressure closely. - **CYP3A4 inhibitors** (e.g., ketoconazole, erythromycin, HIV protease inhibitors): increase sildenafil plasma levels → dose reduction recommended. - **CYP3A4 inducers** (e.g., rifampin, carbamazepine): decrease sildenafil exposure → may reduce efficacy. - **High-fat meals**: can delay absorption and slightly lower peak concentrations; not contraindicated but may affect timing. ## Off-Label and Investigational Uses of Revatio - **Heart Failure with Preserved Ejection Fraction (HFpEF)** - Small trials suggest PDE-5 inhibition may improve pulmonary pressures and exercise tolerance in selected HFpEF patients, though larger studies are required. - **Raynaud’s Phenomenon** - Limited case series report symptom relief, but evidence remains inconclusive and the use is not approved. - **Systemic Sclerosis-Related Pulmonary Hypertension** - Investigational protocols explore Revatio as part of combination therapy; efficacy data are still emerging. All off-label applications must be undertaken only under the direct supervision of a qualified healthcare professional, as safety and benefit profiles have not been formally validated by regulatory agencies. ## Storage & Handling - Store Revatio tablets at controlled room temperature (20 °C-25 °C / 68 °F-77 °F). Protect from excess heat, moisture, and direct sunlight. - Keep the container tightly closed and out of reach of children. - Do not use tablets beyond the printed expiration date; discard any product that appears discolored or degraded. - For disposal, follow local pharmaceutical waste guidelines or return to a pharmacy take-back program. ## Frequently Asked Questions **Practical Use & Lifestyle** - **Can I travel internationally with Revatio?** - Yes, but carry the medication in its original packaging with a copy of the prescription. Check the destination country’s import regulations for prescription drugs before departure. - **Should I avoid grapefruit while taking Revatio?** - Grapefruit juice can inhibit CYP3A4, raising sildenafil levels and increasing side-effect risk. It is advisable to limit grapefruit consumption. - **Is it safe to exercise after taking Revatio?** - Revatio is intended to improve exercise capacity in PAH. Begin physical activity gradually and follow your physician’s guidance, especially during the initial treatment phase. **Product & Formulation Details** - **What do Revatio tablets look like?** - Generic 20 mg sildenafil tablets are typically round, white to off-white, and may be scored to facilitate splitting. Appearance can vary slightly between manufacturers. - **Are there any inactive ingredients I should be aware of?** - Common excipients include lactose, microcrystalline cellulose, and magnesium stearate. Patients with specific intolerances should verify the full ingredient list on the product label. **Regulatory & Safety Nuances** - **Will Revatio appear on a standard drug test?** - Sildenafil is not part of routine employment drug-screening panels, but specialized testing can detect it if specifically requested. - **Can elderly patients use Revatio safely?** - Older adults may be more sensitive to blood-pressure effects. Dose adjustments and careful monitoring are recommended, particularly if concomitant medications affect vascular tone. - **Is Revatio safe during pregnancy or breastfeeding?** - Sildenafil is classified as Category B for pregnancy in animal studies, but human data are insufficient. It is generally avoided unless the benefits outweigh potential risks, and it is not recommended while breastfeeding. **Scientific & Clinical Curiosity** - **How does Revatio differ from Viagra?** - Both contain sildenafil citrate; the primary distinction lies in the approved indication. Viagra is marketed for erectile dysfunction, whereas Revatio is authorized for pulmonary arterial hypertension. - **What pivotal trial led to Revatio’s approval?** - The pivotal Phase III study demonstrated that three times daily dosing of 20 mg sildenafil significantly improved six-minute walk distance and hemodynamic parameters in PAH patients, supporting regulatory approval. ## Glossary **Phosphodiesterase-5 (PDE-5) Inhibitor** : A class of drugs that block the PDE-5 enzyme, leading to increased cGMP levels and vasodilation of blood vessels. **Pulmonary Arterial Hypertension (PAH)** : A progressive disease characterized by high blood pressure in the arteries that supply the lungs, resulting in right-heart strain. **Bioequivalence** : A regulatory standard indicating that two drug products release the same amount of active ingredient into the bloodstream at comparable rates. **cGMP (Cyclic Guanosine Monophosphate)** : A cellular messenger that promotes smooth-muscle relaxation; its concentration is increased when PDE-5 is inhibited. ## Disclaimer The information presented about **Revatio** is intended for general educational purposes and does not substitute professional medical advice.
