Viagra Gold - Vigour (Sildenafil Citrate)

Introduction

Viagra Gold - Vigour is a tablet formulation that contains the phosphodiesterase-5 (PDE-5) inhibitor Sildenafil Citrate. It is supplied in an 800 mg strength and belongs to the class of oral vasodilators used primarily for erectile dysfunction (ED). The product is manufactured by a pharmaceutical company that distributes the medication internationally, and it is listed under the same active ingredient as the well-known brand products marketed under names such as Viagra and Revatio. In addition to its approved use for ED, Sildenafil Citrate is approved in many jurisdictions for the treatment of pulmonary arterial hypertension (PAH). Some clinicians also consider it for off-label applications that have emerging evidence, but such uses are not authorized by regulators such as the U.S. Food and Drug Administration (FDA) or the European Medicines Agency (EMA).

What is Viagra Gold - Vigour?

Viagra Gold - Vigour is a tablet that delivers the active pharmaceutical ingredient Sildenafil Citrate. The medication is classified as a phosphodiesterase-5 (PDE-5) inhibitor. It was originally developed by Pfizer and later generic-produced by various licensed manufacturers worldwide. The specific product is marketed under the name “Viagra Gold - Vigour” and is supplied in an 800 mg tablet form for oral administration.

How Viagra Gold - Vigour Works

Sildenafil Citrate selectively blocks the enzyme PDE-5, which normally degrades cyclic guanosine monophosphate (cGMP) in smooth-muscle cells. In the corpus cavernosum of the penis, sexual stimulation releases nitric oxide, leading to increased cGMP levels. Elevated cGMP causes smooth-muscle relaxation and vasodilation, allowing more blood to fill the erectile tissue. By inhibiting PDE-5, Sildenafil Citrate prolongs the cGMP signal, facilitating erection when sexual arousal occurs.

For pulmonary arterial hypertension, the same mechanism relaxes pulmonary arterial smooth muscle, decreasing pulmonary vascular resistance and improving exercise capacity. Onset of action is typically 30-60 minutes after ingestion, with a therapeutic window of up to 12 hours. The drug is metabolized mainly by hepatic CYP3A4 (and to a lesser extent CYP2C9) and has an elimination half-life of approximately 3-5 hours.

Conditions Treated with Viagra Gold - Vigour

• Erectile Dysfunction (ED) - The principal approved indication. Sildenafil Citrate improves erectile response by enhancing blood flow to the penis during sexual stimulation.
• Pulmonary Arterial Hypertension (PAH) - Commercially sold under the brand name Revatoi in many countries. The drug reduces pulmonary arterial pressure, improves hemodynamics, and increases six-minute walk distance in patients with PAH.

These indications are supported by extensive clinical trial data and are reflected in the product labeling approved by regulatory agencies.

Off-Label and Investigational Uses of Viagra Gold - Vigour

• Raynaud’s Phenomenon - Small pilot studies have reported that low-dose sildenafil may reduce the frequency of digital vasospasm episodes. Evidence remains limited and the safety profile for chronic use in this population is not fully characterized.
• High-Altitude Pulmonary Edema (HAPE) Prophylaxis - Experimental data suggest that PDE-5 inhibition can improve pulmonary arterial pressure at high altitude, potentially lowering HAPE risk. Formal regulatory approval for this indication does not exist.
• Heart Failure with Preserved Ejection Fraction (HFpEF) - Ongoing trials are evaluating whether sildenafil can improve exercise capacity and quality of life in HFpEF patients. Results are pending and the therapy remains investigational.

These off-label applications have not been authorized by the FDA, EMA, or equivalent bodies. Patients should discuss any contemplated off-label use with a qualified healthcare professional, as the benefit-risk balance may differ from that of approved indications.

Is Viagra Gold - Vigour the Right Medication for You?

Suitable candidates for the approved indications include adult males with documented erectile dysfunction who have adequate sexual stimulation and no contraindications, as well as adults diagnosed with pulmonary arterial hypertension who meet criteria for PDE-5 inhibitor therapy.

Clinical scenarios that favor use:

• Inadequate response to lifestyle modification or oral agents of other classes for ED.
• Need for a rapid-onset oral therapy (30-60 minutes).
• PAH patients requiring oral vasodilator therapy without the need for continuous infusion.

Contraindications and cautions:

• Concomitant use of nitrates (e.g., nitroglycerin) or nitric-oxide donors, which can cause severe hypotension.
• Severe uncontrolled hypertension or recent myocardial infarction.
• Known hypersensitivity to sildenafil or any tablet excipients.
• Historic non-arteritic optic neuropathy (NAION) or significant visual disturbance.

Patients with renal or hepatic impairment may require dose adjustments, and those with certain cardiac conditions (e.g., severe aortic stenosis) should be evaluated carefully before initiating therapy.

Risks, Side Effects, and Interactions

Common

• Headache
• Flushing (warmth, redness)
• Dyspepsia (indigestion)
• Nasal congestion
• Visual disturbances (blurred vision, color tinting)

Rare

• Priapism (prolonged erection > 4 hours)
• Auditory loss or ringing in the ears (tinnitus)
• Severe hypotension, especially when combined with nitrates
• Skin rash or mild urticaria

Serious

• Cardiovascular events (myocardial infarction, stroke) in high-risk patients
• Sudden vision loss due to non-arteritic optic neuropathy (NAION)
• Life-threatening hypotension requiring emergency care

Drug-Drug Interactions

• Nitrates (e.g., isosorbide dinitrate, nitroglycerin) → additive vasodilation, risk of severe hypotension.
• Alpha-blockers (e.g., tamsulosin) → may enhance blood pressure-lowering effect.
• CYP3A4 inhibitors (e.g., ketoconazole, ritonavir) → increase sildenafil plasma concentrations; dose reduction recommended.
• CYP3A4 inducers (e.g., rifampin, carbamazepine) → decrease efficacy; may require higher dose.

Food and Lifestyle

• High-fat meals can delay onset of action by up to 1 hour.
• Moderate alcohol consumption is generally tolerated, but excessive intake may increase risk of hypotension and dizziness.
• Patients should avoid operating heavy machinery until they know how the medication affects them.

Use: Dosing, Missed Dose, Overdose

• Standard dosing for ED: Starting dose is typically 50 mg taken orally about 30-60 minutes before sexual activity. Depending on efficacy and tolerability, the dose may be increased to 100 mg or decreased to 25 mg. The maximum recommended frequency is once per day.
• PAH dosing: The approved regimen is usually 20 mg three times daily, taken with food to improve absorption.

Because Viagra Gold - Vigour is supplied as an 800 mg tablet, patients must consult a healthcare professional to verify the appropriate strength and to ensure the tablet can be safely divided or if a lower-strength product is more suitable.

• Missed dose: If a dose is forgotten and the scheduled time for the next dose is less than 12 hours away, skip the missed dose. Do not double-dose to compensate.
• Overdose: Symptoms may include severe headache, hypotension, prolonged erection, or visual changes. Seek emergency medical attention promptly. Supportive care (intravenous fluids, blood pressure monitoring) is the mainstay of treatment; there is no specific antidote.

Practical precautions:

• Take the tablet whole with a glass of water; do not crush or chew.
• Food may delay onset but does not affect overall efficacy.
• Avoid consuming large amounts of alcohol before or after dosing.
• Refrain from operating vehicles or heavy machinery until the individual’s response to the medication is known.

FAQ

• What temperature range should I store Viagra Gold - Vigour in?

  • The tablets should be kept at 20-25 °C (68-77 °F). Protect them from excess heat, moisture, and direct sunlight to maintain potency.

• Can I travel internationally with this medication?

  • Yes, but you should keep the medication in its original packaging, carry a copy of the prescription (if applicable), and verify the import regulations of the destination country to avoid customs issues.

• Does the tablet contain any allergens?

  • Inactive ingredients may include lactose, corn starch, and magnesium stearate. Patients with known allergies to these substances should confirm the exact composition with the supplier.

• How does the 800 mg dose compare to the typical 100 mg tablet?

  • The 800 mg tablet contains eight times the standard 100 mg strength. It is intended for patients whose clinicians have prescribed a higher total daily dose, often divided into several administrations.

• Will taking sildenafil affect a urine drug test?

  • Sildenafil is not classified as a controlled substance and is not screened for in standard occupational drug testing panels.

• Is there a risk of developing tolerance with regular use?

  • Clinical experience suggests that tolerance is uncommon; however, efficacy may diminish if the underlying cause of ED changes (e.g., progression of vascular disease).

• Can I use this medication if I have a mild liver condition?

  • Mild hepatic impairment usually does not require dose adjustment, but moderate to severe liver disease may increase plasma levels, necessitating a lower dose under medical supervision.

• What is the difference between Viagra Gold - Vigour and Revatio?

  • Both contain sildenafil citrate, but Revatio is formulated specifically for PAH at lower daily doses (20 mg three times daily), whereas Viagra Gold - Vigour is marketed primarily for ED and may be supplied in higher strengths.

• Does the medication interact with over-the-counter herbal supplements?

  • Certain herbal products, such as ginkgo biloba or yohimbine, can affect blood pressure and may potentiate sildenafil’s hypotensive effect. Discuss all supplements with a healthcare provider.

• How long does the tablet remain effective after the expiration date?

  • After the printed expiration date, the stability and potency cannot be guaranteed. Use of expired medication is discouraged because degradation may reduce efficacy or increase the risk of adverse reactions.

• Is it safe to take Viagra Gold - Vigour with antihypertensive medication?

  • Generally, sildenafil can be combined with most antihypertensives, but concurrent use with agents that cause profound vasodilation (e.g., nitrates) is contraindicated. Monitoring blood pressure after the first dose is advisable.

• Can I take this medication while on a low-carb diet?

  • A low-carbohydrate diet does not directly affect sildenafil metabolism. However, drastic dietary changes may alter overall cardiovascular health, which should be discussed with a clinician.
