Brand Viagra Information

Introduction

Brand Viagra is a medication whose primary therapeutic purpose is to treat erectile dysfunction (ED) in adult men. It contains the active compound sildenafil, a phosphodiesterase‑5 (PDE‑5) inhibitor that enhances blood flow to the penis during sexual stimulation. In the United Kingdom, Brand Viagra is classified among the best‑selling products for men’s health and is widely prescribed for ED. The drug is also approved for the treatment of pulmonary arterial hypertension (PAH) under the brand name Revatio, reflecting a recognized secondary use.

What is Brand Viagra?

Brand Viagra is a tablet formulation that delivers a fixed dose of sildenafil citrate. The product belongs to the class of PDE‑5 inhibitors, which were first introduced in the early 199s. The original brand‑name version, Viagra, was developed and marketed by Pfizer after a series of clinical trials demonstrated its efficacy and safety for erectile dysfunction. Brand Viagra is manufactured by licensed pharmaceutical partners that adhere to the United Kingdom’s Medicines and Healthcare products Regulatory Agency (MHRA) standards for quality and safety.

How Brand Viagra Works

Sildenafil works by selectively inhibiting the enzyme phosphodiesterase‑5 in the smooth muscle cells lining the corpus cavernosum of the penis. Under normal circumstances, sexual arousal releases nitric oxide (NO), which stimulates the production of cyclic guanosine monophosphate (cGMP). cGMP relaxes smooth muscle, allowing blood to fill the erectile tissue. PDE‑5 degrades cGMP, terminating the erection. By blocking this enzyme, sildenafil prolongs the action of cGMP, facilitating sustained inflow of blood and thus supporting erection in response to sexual stimulation.

Key pharmacokinetic points:

• Onset of action: 30–60 minutes after oral intake, depending on food intake and individual metabolism.
• Peak plasma concentration: Approximately 1 hour post‑dose.
• Duration of effect: Typically 4–6 hours, with residual activity up to 12 hours in some individuals.
• Elimination: Primarily hepatic metabolism via CYP3A4, with a half‑life of about 4 hours.

Conditions Treated with Brand Viagra

• Erectile Dysfunction (ED) – The most common indication. In the UK, ED affects an estimated 20 % of men aged 40–70, with prevalence rising with age and comorbid conditions such as diabetes and cardiovascular disease. Sildenafil improves the ability to achieve and maintain an erection sufficient for sexual activity.
• Pulmonary Arterial Hypertension (PAH) – Under the brand Revatio, sildenafil is indicated for PAH, a rare condition characterized by high pressure in the pulmonary arteries that leads to shortness of breath and reduced exercise capacity. By dilating pulmonary vessels, sildenafil reduces pulmonary vascular resistance.

Suitable Candidates for Brand Viagra Treatment

• Men with diagnosed erectile dysfunction who have a functional vascular system and no contraindications to PDE‑5 inhibition.
• Patients with PAH who require oral vasodilator therapy as part of a comprehensive treatment plan.
• Individuals who have tried lifestyle modification (e.g., weight loss, smoking cessation) without sufficient improvement in erectile function.

Contraindications and cautionary scenarios

• Men taking nitrates (e.g., nitroglycerin) for angina, as concurrent use can cause severe hypotension.
• Patients with severe uncontrolled hypertension or recent myocardial infarction, because sudden vasodilation may stress the cardiovascular system.
• Individuals with known hypersensitivity to sildenafil or any tablet excipients.
• Use in children and adolescents is not approved.

Risks, Side Effects, and Interactions

Common

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

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

Rare

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

Patients experiencing any rare event should seek medical advice promptly.

Serious

• Cardiovascular events (e.g., myocardial infarction, stroke) in patients with pre‑existing heart disease.
• Life‑threatening hypotension leading to syncope or falls.

Any serious adverse reaction warrants immediate emergency care.

Drug–Drug Interactions

• Nitrates (e.g., glyceryl trinitrate, isosorbide dinitrate) – risk of profound hypotension.
• Alpha‑blockers (e.g., tamsulosin) – may cause additive blood pressure lowering.
• CYP3A4 inhibitors (e.g., ketoconazole, erythromycin, ritonavir) – increase sildenafil plasma levels, raising the risk of side effects.
• CYP3A4 inducers (e.g., rifampicin, carbamazepine) – may reduce efficacy.

Patients should disclose all current medications to their healthcare provider before initiating Brand Viagra.

Practical Use: Dosing, Missed Dose, Overdose

• Standard starting dose for ED: 50 mg taken as a single tablet, orally, approximately 1 hour before anticipated sexual activity.
• Dose adjustments: May be increased to 100 mg or decreased to 25 mg based on efficacy and tolerability. No more than one tablet per 24‑hour period.
• PAH dosing: Typically 20 mg three times daily, taken at evenly spaced intervals.

Missed dose – If an ED dose is missed, it should be taken as soon as possible, but not later than 4 hours before the next planned sexual activity. Do not take two tablets together to “make up” for a missed dose.

Overdose – Symptoms may include severe hypotension, prolonged erection, or marked dizziness. Seek urgent medical attention. Supportive care, such as intravenous fluids and blood pressure monitoring, is the mainstay of treatment.

Practical precautions

• Food: High‑fat meals can delay absorption and reduce peak concentration; advisable to take the tablet on an empty stomach for faster onset.
• Alcohol: Moderate consumption is generally safe, but excessive intake can exacerbate hypotensive effects and impair sexual performance.
• Comorbidities: Patients with severe liver impairment should use a reduced dose (25 mg) due to slower drug clearance.

FAQ

• Is Brand Viagra available in both brand‑name and generic forms in the UK?
  Yes. The original brand‑name product, Viagra, is manufactured by Pfizer, while generic versions containing the same amount of sildenafil are produced by multiple licensed manufacturers. Generic formulations are typically less expensive but meet the same regulatory standards.

• What is the recommended storage condition for Brand Viagra tablets?
  Store tablets at room temperature (15–30 °C). Keep the medication in the original blister pack, away from moisture, direct sunlight, and heat sources such as radiators or car dashboards.

• Does the appearance of Brand Viagra tablets differ between regions?
  In the UK, generic sildenafil tablets often have a distinct imprint, shape, and colour that vary by manufacturer. The original Pfizer product is a blue, diamond‑shaped tablet marked with “VIAGRA 100 mg.” Regional variations reflect differing inactive excipients and regulatory labelling requirements.

• Can Brand Viagra be safely imported for personal use under UK law?
  Personal import of medicines for personal use is permitted if the product is for a legitimate medical purpose, is not a controlled substance, and the quantity does not exceed a three‑month supply. Importers must ensure the medication is sourced from a reputable, MHRA‑registered supplier.

• Are there any specific warnings for Asian populations taking Brand Viagra?
  Pharmacogenomic studies indicate that individuals of East Asian descent may have reduced CYP3A4 activity, leading to higher plasma levels of sildenafil. Clinicians often start with a lower dose (25 mg) and titrate based on response and tolerability.

• How does alcohol consumption affect the efficacy of Brand Viagra?
  Moderate alcohol intake does not substantially alter sildenafil pharmacokinetics, but excessive drinking can impair the physiological processes required for erection and may increase the risk of hypotension. Patients are advised to limit alcohol to a few units when planning sexual activity.

• What are the differences between the 25 mg, 50 mg, and 100 mg dosages?
  The 25 mg dose is intended for patients who are sensitive to side effects or who are initiating therapy. The 50 mg dose is the standard starting point for most men. The 100 mg dose is reserved for those who have not achieved satisfactory results with lower doses and who tolerate the medication well.

• Does taking a high‑fat meal delay the onset of action?
  Yes. A high‑fat meal can reduce the rate of absorption, postponing the peak plasma concentration by up to 60 minutes. For quicker onset, the tablet should be taken on an empty stomach or after a light meal.

• Is there a risk of false‑positive drug tests when using Brand Viagra?
  Sildenafil is not a substance screened for in standard workplace or sport drug‑testing panels. It is not listed as a prohibited substance by the World Anti‑Doping Agency (WADA), and routine tests will not detect it.

• How long has sildenafil been on the market, and what were its original development goals?
  Sildenafil was first patented in 1989 and approved by the US FDA in 1998 for erectile dysfunction. Initially, the compound was investigated as a potential treatment for angina pectoris because of its vasodilatory properties. The unexpected erectile effect redirected its development toward ED, leading to worldwide commercial success.
