Revatio, known scientifically as Sildenafil 20 mg, plays a significant role in addressing pulmonary arterial hypertension. This condition demands a precise medical intervention. Understanding the pharmacological journey of this drug offers insights into its role in therapy.

Pharmacokinetics

Sildenafil is swiftly absorbed in the body. Its bioavailability hovers around 40%, affected by high-fat meals which delay absorption. The compound shows a maximum plasma concentration approximately 1 hour post-administration. It binds extensively to plasma proteins, specifically albumin and alpha-1 acid glycoprotein. Its half-life is about 4 hours, suggesting its requirement for multiple dosing throughout the day.

The liver primarily metabolizes Sildenafil through CYP3A4 and CYP2C9. It undergoes extensive first-pass metabolism, with a clearance of 41 L/h. Renal and fecal pathways facilitate its excretion. Hepatic impairment prolongs its effect, necessitating dose adjustment in such patients.

Dosage Information

The standard dose of Revatio is 20 mg, administered thrice daily. This ensures a steady state of drug levels in the body. The interval between doses must be approximately 4-6 hours. Dose adjustments are not generally required in geriatric patients or those with mild to moderate renal impairment. In severe renal or hepatic impairment, caution is advised, often entailing a reduced frequency.

Patients must adhere to their prescribed regimen. Missed doses should be taken as soon as remembered unless the next dose is near. Doubling doses to compensate is not recommended. Adherence maximizes therapeutic outcomes while minimizing adverse effects.

FDA-Approved Indications

The FDA endorses Revatio for the treatment of pulmonary arterial hypertension (PAH). It targets the elevation of pulmonary blood pressure. PAH, a life-threatening disorder, impairs physical activity due to elevated pressures in the pulmonary arteries. Sildenafil 20 mg ameliorates this condition by dilating pulmonary vessels, thus reducing the arterial pressure.

Its role in enhancing exercise capacity is well-documented. Clinical trials underpin its efficacy, showcasing improvements in hemodynamics and functional capacity. Notably, this medication is not approved for pediatric use, highlighting the need for cautious application based on demographic and individual health factors.

Cautions with Other Medicines

Drug interactions with Sildenafil necessitate caution. Nitrate use is contraindicated due to the risk of hypotension. Alpha-blockers can precipitate symptomatic blood pressure drops, necessitating staggered administration. Cautious co-administration with CYP3A4 inhibitors, such as erythromycin or ketoconazole, is recommended.

Concomitant use of protease inhibitors requires dose reduction. Antihypertensives may have their effect amplified, thus close monitoring of blood pressure is advised. Patients should disclose all concurrent medications to their healthcare provider to mitigate interaction risks.

How to Cope with Side Effects of Revatio

Revatio is associated with side effects such as headaches, flushing, dyspepsia, and nasal congestion. Most are mild to moderate and diminish with continued therapy. Adequate hydration and avoiding triggers, such as bright lights or hot weather, can alleviate headaches and flushing.

Gastrointestinal discomfort may be mitigated by smaller, more frequent meals. Over-the-counter antacids may relieve dyspepsia. Persistent or severe symptoms warrant medical consultation. Early identification and management are crucial to ensuring compliance and optimizing treatment efficacy.

Purchase Revatio No Prescription

Acquiring Revatio without a prescription is inadvisable. It is crucial to ensure proper medical guidance when using this medication. Professional consultation ensures that the treatment aligns with individual health profiles and safety parameters.

Pharmacies require valid prescriptions to dispense this drug. Patients are encouraged to consult healthcare providers to discuss treatment suitability. Medical oversight guarantees the appropriateness of therapy, minimizing the potential for adverse effects and interactions.

Side Effect	Management
Headache	Hydration, rest, OTC analgesics
Flushing	Avoid heat, stay cool
Dyspepsia	Small meals, antacids
Nasal Congestion	Nasal decongestants
