Generic Viagra Black (Sildenafil Citrate)

Introduction

Viagra Black is a tablet formulation that contains the active compound sildenafil citrate. It is supplied at a strength of 200 mg per pill and belongs to the class of phosphodiesterase-type 5 (PDE5) inhibitors. The medication is primarily approved for the treatment of erectile dysfunction (ED) in adult men. Sildenafil citrate is also the active ingredient in other licensed products, such as those marketed under brand names such as Viagra and Revatio, which are authorized for the same primary indication and, in the case of Revatio, for pulmonary arterial hypertension. The 200 mg dosage provides a higher-strength option for individuals who have not achieved satisfactory results with lower doses, under medical supervision.

What is Viagra Black?

Viagra Black is a generic tablet that delivers sildenafil citrate, the same molecule found in the well-known brand-name products Viagra and Revatio. The product is manufactured by an undisclosed pharmaceutical company that follows Good Manufacturing Practice (GMP) standards and holds the necessary regulatory approvals for distribution in the regions where it is sold.

Viagra Black is the generic version of well-known medications, containing the active compound sildenafil citrate. Our online pharmacy provides this generic alternative as a cost-effective treatment option for patients who need a reliable PDE5 inhibitor but prefer a lower-cost formulation.

How Viagra Black Works

Sildenafil citrate inhibits the enzyme phosphodiesterase-type 5 (PDE5). In the corpus cavernosum of the penis, nitric oxide released during sexual stimulation activates guanylate cyclase, increasing cyclic guanosine monophosphate (cGMP). Elevated cGMP relaxes smooth muscle, allowing blood to fill the erectile tissue. PDE5 breaks down cGMP, terminating the erection. By blocking PDE5, sildenafil prolongs the presence of cGMP, enhancing and sustaining erections in response to sexual arousal.

Pharmacokinetic data indicate that peak plasma concentrations occur within 30-60 minutes after oral ingestion. The therapeutic effect typically lasts 4-6 hours, although efficacy may persist up to 12 hours in some individuals. Sildenafil is metabolized mainly by the cytochrome P450 enzymes CYP3A4 and CYP2C9 and eliminated primarily via renal excretion.

Conditions Treated with Viagra Black

• Erectile Dysfunction (ED): Sildenafil citrate is approved by the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for the treatment of ED in adult men. The drug improves erectile response by enhancing the nitric-oxide-cGMP pathway, enabling successful intercourse when sexual stimulation is present.

• Pulmonary Arterial Hypertension (PAH) - off-label: While the branded formulation Revatio is specifically approved for PAH, the same active molecule (sildenafil) can be used under specialist supervision for this indication. In PAH, inhibition of PDE5 leads to pulmonary vascular smooth-muscle relaxation, reducing pulmonary arterial pressure and improving exercise capacity.

Off-Label and Investigational Uses of Viagra Black

Sildenafil citrate has been studied in several clinical contexts beyond its approved indications. Evidence from peer-reviewed trials suggests potential benefits, but these uses lack formal regulatory approval.

• Raynaud’s Phenomenon: Small-scale studies have shown that sildenafil may improve digital blood flow in severe Raynaud’s, likely through vasodilation of peripheral arteries.

• High-Altitude Pulmonary Edema (HAPE): Preliminary research indicates that PDE5 inhibition can reduce hypoxic pulmonary vasoconstriction, offering protective effects in high-altitude exposure.

• Benign Prostatic Hyperplasia (BPH)-related lower urinary tract symptoms: Some trials report that sildenafil improves urinary flow rates, possibly via smooth-muscle relaxation in the prostate and bladder neck.

• Fertility in men: Limited data suggest that sildenafil could enhance seminal parameters by improving testicular blood flow, though results are inconsistent.

These applications are not approved by regulatory agencies. Patients should only consider off-label use after a thorough discussion with a qualified healthcare provider who can evaluate the risk-benefit profile for the individual case.

Is Viagra Black the Right Medication for You?

Viagra Black is appropriate for adult males who have a confirmed diagnosis of erectile dysfunction and who have not achieved satisfactory outcomes with lower-strength PDE5 inhibitors (e.g., 25 mg, 50 mg, or 100 mg). It is also considered for patients requiring a higher potency dose under specialist guidance.

Suitable candidates typically:

• Have a medically documented cause of ED (vascular, neurogenic, psychogenic, or medication-related).
• Are not taking nitrates or nitric-oxide donors, as concurrent use can cause dangerous hypotension.
• Have normal renal and hepatic function or mild impairment that does not require dose reduction.

The medication is contraindicated in:

• Patients with a known hypersensitivity to sildenafil or any tablet excipients.
• Individuals using potent CYP3A4 inhibitors (e.g., ketoconazole, ritonavir) without dose adjustment.
• Those with severe cardiovascular disease where sexual activity may pose a risk (e.g., recent myocardial infarction, uncontrolled arrhythmias).

Risks, Side Effects, and Interactions

Common

• Headache
• Facial flushing
• Dyspepsia (indigestion)
• Nasal congestion
• Visual disturbances (e.g., blue-tinted vision)

These events are generally mild, transient, and resolve without medical intervention.

Rare

• Priapism (prolonged erection lasting >4 hours)
• Sudden hearing loss
• Severe hypotension when combined with nitrates

Patients experiencing any of these symptoms should seek medical attention promptly.

Serious

• Cardiovascular events (myocardial infarction, stroke) in patients with pre-existing heart disease.
• Non-arteritic ischemic optic neuropathy (vision loss).
• Allergic reactions such as angioedema or anaphylaxis.

Immediate emergency care is required for serious adverse reactions.

Drug-Drug Interactions

• Nitrates (e.g., nitroglycerin, isosorbide dinitrate): additive vasodilatory effect → risk of severe hypotension.
• Potent CYP3A4 inhibitors (ketoconazole, itraconazole, clarithromycin, ritonavir): increase sildenafil plasma levels → higher risk of side effects; dose reduction may be necessary.
• Alpha-blockers (e.g., tamsulosin, doxazosin): may cause additive blood-pressure lowering; monitor closely.

Drug-Food Interactions

• High-fat meals can delay absorption, postponing onset of action by up to 1 hour.
• Alcohol in excess may exacerbate blood-pressure lowering and increase the likelihood of dizziness.

Use: Dosing, Missed Dose, Overdose

Standard dosing for erectile dysfunction starts at 50 mg taken about 30 minutes before sexual activity, not more than once per day. The dose may be increased to 100 mg or 200 mg based on efficacy and tolerability. For patients requiring the 200 mg strength, a physician may prescribe this as a single daily dose or as needed, adhering to the once-daily limit.

If a dose is missed, there is no “missed dose” concept because sildenafil is taken only when sexual activity is anticipated. Patients should simply wait until the next appropriate opportunity; duplication of a dose within a 24-hour period is not recommended.

In the event of a suspected overdose, patients should seek immediate medical attention. Symptoms of overdose may include profound hypotension, fainting, severe headache, or prolonged erection. Management is supportive, focusing on blood-pressure stabilization and monitoring for priapism.

Practical precautions

• Take the tablet with water; food can be consumed but a high-fat meal may delay effect.
• Avoid excessive alcohol, which can increase dizziness and lower blood pressure.
• Do not operate heavy machinery or drive if you feel impaired after dosing.

FAQ

• What is the appearance of a Viagra Black 200 mg tablet? The tablet is typically round, blue-white, and imprinted with “200 mg” on one side and the manufacturer’s logo on the other.

• Can Viagra Black be stored in a humid environment? Sildenafil tablets should be kept in a dry place at controlled room temperature (15-25 °C). High humidity can degrade the active ingredient over time.

• Is it safe to travel internationally with Viagra Black? When traveling, keep the medication in its original packaging with a copy of the prescription (if required). Check the destination country’s import regulations; many allow personal import of up to three months’ supply for personal use.

• Does Viagra Black appear on standard drug tests? Sildenafil is not typically screened for in standard occupational drug tests. However, specialized testing could detect it if specifically requested.

• How does the 200 mg dose differ from lower strengths in terms of efficacy? Clinical trials have shown a dose-response relationship: higher doses can increase the likelihood of achieving an erection sufficient for intercourse, particularly in patients who did not respond to 50 mg or 100 mg.

• What inactive ingredients are present in Viagra Black? Common excipients include lactose, microcrystalline cellulose, magnesium stearate, and silicon dioxide. Patients with specific allergies should review the full ingredient list.

• Are there regional formulation differences for sildenafil tablets? Formulation may vary slightly between manufacturers, affecting tablet color, size, and disintegration time, but the active dose and bioavailability remain consistent across approved products.

• Can sildenafil be used in patients with mild renal impairment? Mild renal impairment generally does not require dose adjustment, but severe impairment (eGFR < 30 mL/min) may necessitate a lower starting dose and careful monitoring.

• What is the mechanism behind sildenafil’s effect on pulmonary hypertension? By inhibiting PDE5 in pulmonary vascular smooth muscle, sildenafil increases cGMP levels, leading to vasodilation and reduced pulmonary arterial pressure, which improves exercise capacity in PAH patients.

• Is it advisable to take Viagra Black with a high-fat meal before sexual activity? A high-fat meal can delay the onset of action by up to an hour, potentially reducing spontaneity. For a more predictable effect, a light meal or fasting state is preferred.
