Pharmacokinetics
Revatio 20 mg is primarily administered to manage pulmonary arterial hypertension. It contains sildenafil citrate, a potent phosphodiesterase-5 inhibitor. Upon oral ingestion, it reaches peak plasma concentration within an hour. Metabolism occurs mainly in the liver, through cytochrome P450 enzymes. The half-life is about four hours. It is excreted predominantly via feces. Sildenafil 20 mg is absorbed efficiently when administered intravenously, with swift systemic availability.
Food impacts the drug’s absorption slightly. The presence of high-fat meals can delay absorption, lowering peak concentrations. However, the overall bioavailability remains unaffected. Clinically, this makes it versatile for patients with varying dietary needs. The predictable pharmacokinetic profile ensures consistency across administrations.
Areas of Use
Revatio is prescribed for treating pulmonary arterial hypertension. It alleviates symptoms by relaxing blood vessels, reducing blood pressure in the lungs. This allows better oxygen flow, improving exercise capacity. It’s sometimes used off-label for altitude sickness and Raynaud’s phenomenon, though this requires medical discretion.
Revatio’s role in managing heart conditions makes it crucial for those with specific cardiovascular concerns. It’s not designed for erectile dysfunction, despite its active ingredient’s presence in other medications for such conditions.
Who Can and Cannot Take Revatio
Most adults can safely use sildenafil 20 mg for pulmonary arterial hypertension. However, those with severe liver or kidney impairment should avoid it. It’s contraindicated in patients using nitrates or nitric oxide donors, due to risk of significant hypotension. Children and pregnant women should only use it under strict medical supervision.
Allergies to sildenafil or any formulation components preclude its use. Those with rare hereditary galactose intolerance should also refrain from taking Revatio tablets due to excipient content. Comprehensive medical history is vital to determine suitability.
Missed Dose
If a dose is missed, take it as soon as remembered. If it’s near the time for the next dose, skip the missed one. Doubling doses can lead to adverse effects. Consistency in administration aids in managing the condition effectively. Adhering to the prescribed schedule ensures optimal benefit from the medication.
Adverse Effects
Common side effects include headaches, flushing, and indigestion. Some may experience nasal congestion or visual disturbances. Rare but severe reactions encompass sudden hearing loss or heart attack symptoms. These require immediate medical attention.
- Vision changes, especially blue-tinted vision
- Prolonged erections (priapism)
- Rapid heartbeat or palpitations
Continuous monitoring for these symptoms can prevent complications. Report any unexpected reactions to a healthcare provider promptly. This ensures safety and effectiveness throughout the treatment course.
