Silagra Information

Introduction

Silagra is a prescription medication used primarily for the treatment of erectile dysfunction (ED) in adult men. The product contains the active compound sildenafil, a phosphodiesterase‑5 (PDE‑5) inhibitor that enhances erectile response by improving blood flow to the penile tissue. In Hong Kong, erectile dysfunction affects an estimated 10 % of men aged 40 years and older, making effective and affordable therapy a public health priority. Silagra is marketed within the men's health therapeutic group and is also recognised for off‑label use in pulmonary arterial hypertension (PAH) when prescribed by a specialist.

What is Silagra?

Silagra is a tablet formulation that delivers sildenafil citrate in fixed doses. It belongs to the class of phosphodiesterase‑5 inhibitors, which were first introduced in the early 199s for the management of erectile dysfunction. The medication is manufactured by a licensed pharmaceutical company that complies with Good Manufacturing Practice (GMP) standards; the exact manufacturer may vary by batch, but all suppliers are required to hold a valid registration with the Hong Kong Department of Health.

Silagra is the generic version of the well‑known brand Viagra®, containing the same active ingredient, dosage strengths, and therapeutic profile. Our online pharmacy provides this generic alternative as a cost‑effective treatment option for men who require reliable ED management without the premium price of brand‑name products.

How Silagra Works

Sildenafil exerts its effect by selectively blocking the enzyme phosphodiesterase‑5 (PDE‑5) in smooth‑muscle cells of the corpus cavernosum. Under sexual stimulation, nitric oxide (NO) is released from endothelial cells and nerve endings, triggering the synthesis of cyclic guanosine monophosphate (cGMP). cGMP relaxes smooth muscle, allowing arterial inflow and erection. PDE‑5 normally degrades cGMP, limiting the duration of an erection. By inhibiting PDE‑5, sildenafil prolongs cGMP activity, resulting in sustained smooth‑muscle relaxation and enhanced penile rigidity.

The pharmacokinetic profile of sildenafil shows rapid absorption, with peak plasma concentrations occurring 30–120 minutes after oral ingestion. Food, especially high‑fat meals, can delay absorption by up to one hour but does not affect overall exposure. The drug’s elimination half‑life is approximately 4 hours, and it is primarily cleared by hepatic metabolism via CYP3A4, with renal excretion accounting for a minor portion of the dose. These properties explain the typical onset of action within 30 minutes and a therapeutic window lasting up to 6 hours.

Conditions Treated with Silagra

• Erectile Dysfunction (ED) – The principal indication. Sildenafil restores the physiological cascade needed for an erection in men with vasculogenic, neurogenic, or psychogenic ED.
• Pulmonary Arterial Hypertension (PAH) – Approved in several jurisdictions for the treatment of PAH under the brand name Revatio®. In PAH, sildenafil reduces pulmonary vascular resistance, improving exercise capacity and delaying disease progression.

In Hong Kong, the prevalence of ED rises sharply after age 50, with lifestyle factors such as diabetes, hypertension, and smoking contributing to endothelial dysfunction. Sildenafil’s vasodilatory action directly addresses this pathophysiology, making it a first‑line oral therapy according to local clinical guidelines.

Who is Silagra For?

Silagra is appropriate for adult men who:

• Have a documented diagnosis of erectile dysfunction and require pharmacologic assistance to achieve satisfactory sexual performance.
• Are able to take oral medication and have no contraindications to PDE‑5 inhibition (e.g., concurrent nitrate therapy).
• Possess stable cardiovascular status; mild to moderate hypertension or controlled coronary artery disease are not absolute barriers.

Silagra is not recommended for:

• Men taking nitrates (e.g., nitroglycerin) or nitric‑oxide donors, because combined vasodilation can cause profound hypotension.
• Patients with severe left‑ventricular outflow obstruction, recent myocardial infarction (within 30 days), or uncontrolled severe hypertension (>180/110 mmHg).
• Individuals with known hypersensitivity to sildenafil or any tablet excipients.

Risks, Side Effects, and Interactions

Common

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

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

Rare

• Priapism (erection lasting >4 hours) – requires urgent evaluation.
• Sudden hearing loss or tinnitus.
• Severe allergic reactions, including rash, pruritus, or angioedema.

Serious

• Cardiovascular events (e.g., myocardial infarction, stroke) in patients with pre‑existing heart disease.
• Non‑arteritic anterior ischemic optic neuropathy (NAION) – rare but vision‑threatening.
• Life‑threatening hypotension when combined with nitrates or potent α‑blockers.

Clinically Relevant Drug–Drug Interactions

• Nitrates (nitroglycerin, isosorbide dinitrate): additive vasodilation → severe hypotension.
• Alpha‑blockers (e.g., tamsulosin): may cause symptomatic blood pressure drops; stagger dosing by at least 4 hours.
• CYP3A4 inhibitors (ketoconazole, ritonavir, clarithromycin): increase sildenafil plasma levels → higher risk of adverse events; dose reduction may be necessary.
• CYP3A4 inducers (rifampin, carbamazepine): reduce sildenafil exposure → may diminish efficacy.

Patients should disclose all current medications, including over‑the‑counter products and herbal supplements, to their healthcare provider before initiating Silagra.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing for ED:

  • Initiate with 50 mg taken as a single tablet about 30 minutes before anticipated sexual activity.
  • The dose may be adjusted to 25 mg (for those with mild hepatic impairment or heightened sensitivity) or increased to 100 mg (maximum) based on efficacy and tolerability.
  • Do not exceed one tablet per 24‑hour period.

• Pulmonary arterial hypertension (when prescribed by a specialist):

  • Typical regimen is 20 mg taken three times daily, spaced evenly (e.g., morning, midday, evening).

• Missed dose: If an erection does not occur, a missed dose should be ignored; take the next dose at the usual time. Do not double‑dose to compensate.

• Overdose: Signs may include severe hypotension, prolonged erection, dizziness, or fainting. Immediate medical evaluation is essential. Symptomatic treatment (e.g., intravenous fluids, vasopressors) is administered in a clinical setting.

• Food & Alcohol: A high‑fat meal can delay absorption; moderate alcohol intake is permissible but excessive consumption may exacerbate hypotension and dizziness.

• Comorbidities: Dose adjustment may be required for patients with moderate hepatic impairment (Child‑Pugh B) or severe renal dysfunction (eGFR < 30 mL/min).

FAQ

• **Can Silagra be taken with a high‑fat meal?
  Yes, a high‑fat meal may delay the onset of action by up to one hour but does not reduce overall effectiveness. To achieve the quickest effect, take the tablet on an empty stomach or after a light meal.

• **What are the visual side effects associated with Silagra?
  Some users report transient changes such as blue‑tinted vision, increased sensitivity to light, or blurred vision. These effects are typically mild, resolve within a few hours, and do not indicate permanent ocular damage.

• **Is it safe to store Silagra in a humid environment like a bathroom?
  Silagra tablets should be stored at a controlled room temperature (15–30 °C) away from moisture, direct sunlight, and heat sources. A bathroom’s fluctuating humidity can degrade the tablet’s integrity over time.

• **Does Silagra require prescription verification before shipment?
  Our online pharmacy operates as a broker and works with licensed overseas pharmacies that require a valid prescription from a qualified healthcare professional before dispensing.

• **Can travelers bring Silagra into Hong Kong for personal use?
  Yes, personal import of up to a 30‑day supply of prescription medication is permitted for residents, provided the medication is for personal use and accompanied by a copy of the prescription.

• **Are there differences in tablet appearance between regional manufacturers?
  Generic sildenafil tablets, including Silagra, may vary in color, shape, and imprint depending on the source manufacturer, but all contain the same amount of active ingredient and meet the same regulatory standards.

• **What is the typical shelf‑life of Silagra tablets?
  The standard expiration period is two years from the date of manufacture, as indicated on the product label. Always check the expiry date before use.

• **How does Silagra compare to older ED drugs such as alprostadil?
  Sildenafil (Silagra) works systemically to enhance the natural erectile response, whereas alprostadil is administered locally (injection or intraurethral). Sildenafil is generally preferred for its oral route, rapid onset, and ease of use, while alprostadil may be considered when PDE‑5 inhibitors are contraindicated.

• **Is there a risk of developing tolerance to Silagra with long‑term use?
  Clinical studies have not demonstrated significant pharmacologic tolerance to sildenafil over extended periods. Effectiveness is maintained when the medication is used as prescribed.

• **Can Silagra affect results of drug testing for employment?
  Sildenafil is not a controlled substance and is not screened for in standard occupational drug tests. However, specialized testing for performance‑enhancing agents may detect it if specifically requested.

• **Do Asian populations experience different side‑effect profiles with Silagra?
  Pharmacogenomic data suggest similar efficacy and safety across ethnic groups. Minor variations in metabolism due to CYP3A4 activity have not translated into clinically significant differences in dosing for the majority of Asian patients.

Glossary

Phosphodiesterase‑5 (PDE‑5) Inhibitor

A class of drugs that block the enzyme responsible for breaking down cGMP, thereby promoting smooth‑muscle relaxation and increased blood flow in the penis.

cGMP (Cyclic Guanosine Monophosphate)

A messenger molecule that mediates the relaxation of smooth muscle tissue during sexual arousal; its levels are increased by nitric oxide and sustained by PDE‑5 inhibition.

Priapism

An erection lasting longer than four hours that is not related to sexual stimulation; it is a medical emergency because prolonged ischemia can damage penile tissue.
