Generic Sildigra Information

Introduction

Sildigra is a tablet formulation containing the phosphodiesterase‑5 (PDE5) inhibitor sildenafil. It is classified under the therapeutic group “Erectile Dysfunction (ED) – Men’s Health”. In Hong Kong, sildenafil‑based medicines are prescribed for men who experience difficulty achieving or maintaining an erection sufficient for sexual activity. The same active compound is also approved for the treatment of pulmonary arterial hypertension (PAH) under a different brand name. Sildigra provides a cost‑effective, locally accessible option for patients seeking reliable symptom control while meeting Hong Kong regulatory standards.

What is Sildigra?

Sildigra is a tablet containing 25 mg, 50 mg, or 100 mg of sildenafil citrate, the same active ingredient found in the original brand‑name product Viagra® (Pfizer) for erectile dysfunction and Revatio® for pulmonary arterial hypertension. The product is manufactured by an internationally accredited pharmaceutical company that complies with Good Manufacturing Practice (GMP) guidelines; the specific manufacturer is listed on the packaging supplied to our pharmacy.

Sildigra is the generic version of these well‑known brands, containing the identical chemical entity and delivering comparable therapeutic outcomes when taken as directed. Our online pharmacy provides this generic alternative as a cost‑effective treatment option for adult men in Hong Kong.

How Sildigra Works

Sildenafil belongs to the phosphodiesterase‑5 inhibitor class. In the cavernous tissue of the penis, sexual stimulation triggers the release of nitric oxide (NO). NO activates guanylate cyclase, which increases cyclic guanosine monophosphate (cGMP). Elevated cGMP relaxes smooth muscle, allowing arterial inflow and erection.

PDE5 is an enzyme that rapidly degrades cGMP. By selectively inhibiting PDE5, sildenafil prolongs the cGMP signal, maintaining smooth‑muscle relaxation and facilitating blood flow. The effect is activity‑dependent; the drug does not cause an erection without sexual stimulation.

Typical pharmacokinetic parameters:

• Onset of action: 30–60 minutes after oral ingestion.
• Peak plasma concentration: 1–2 hours.
• Duration of effect: Up to 4–6 hours, varying with dose and individual metabolism.
• Elimination half‑life: Approximately 4 hours, primarily via hepatic metabolism (CYP3A4) and renal excretion.

For PAH, the same mechanism reduces pulmonary vascular resistance by dilating pulmonary arterial smooth muscle, improving exercise capacity.

Conditions Treated with Sildigra

• Erectile Dysfunction (ED) – The principal indication. In Hong Kong, epidemiological surveys estimate that 10–20 % of men aged 40–70 experience some degree of ED, a prevalence that rises with age, diabetes, hypertension, and metabolic syndrome. Sildenafil restores sufficient erectile rigidity for satisfactory sexual intercourse.

• Pulmonary Arterial Hypertension (PAH) – Although the branded formulation Revatio is the typical label for PAH, the same active ingredient is used off‑label in some jurisdictions. In Hong Kong, PAH prevalence is low (≈15 cases per million) but carries high morbidity; PDE5 inhibition reduces pulmonary artery pressure and improves functional class.

• Secondary Uses (off‑label) – Some clinicians prescribe sildenafil for Raynaud’s phenomenon, high‑altitude pulmonary edema, and certain forms of benign prostatic hyperplasia‑related lower urinary tract symptoms, owing to its vasodilatory properties. These uses are not formally approved in Hong Kong and should be undertaken only under specialist supervision.

Who is Sildigra For?

• Adult men with clinically diagnosed erectile dysfunction who are otherwise healthy or have stable chronic conditions (e.g., controlled hypertension, type 2 diabetes).

• Patients with pulmonary arterial hypertension when prescribed by a cardiology or respiratory specialist, typically at lower daily doses (e.g., 20 mg three times daily).

• Men who have failed non‑pharmacologic ED interventions such as vacuum devices or lifestyle modifications.

• Individuals seeking a discreet, affordable oral therapy that can be taken on an “as‑needed” basis (30 minutes to 1 hour before sexual activity).

Contraindications / situations where Sildigra may not be appropriate:

• Concurrent use of nitrates (e.g., nitroglycerin) or nitric‑oxide donors, because combined vasodilation can cause severe hypotension.
• Unstable cardiovascular disease (recent myocardial infarction, uncontrolled angina, severe arrhythmia).
• Severe hepatic or renal impairment without dose adjustment.
• Known hypersensitivity to sildenafil or any tablet excipients (e.g., lactose, magnesium stearate).
• Patients aged < 18 years; safety and efficacy have not been established in the pediatric population.

A thorough medical history and physical examination are essential before initiating therapy.

Risks, Side Effects, and Interactions

Common

• Headache
• Flushing (warmth or reddening of the face, neck, or chest)
• Dyspepsia or indigestion
• Nasal congestion
• Visual disturbances (blurred vision, color tinge, increased light sensitivity)

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

Rare

• Priapism (prolonged erection lasting > 4 hours) – requires prompt medical attention to prevent permanent tissue damage.
• Sudden hearing loss or tinnitus.
• Severe hypotension (particularly when combined with antihypertensive agents).
• Dermatologic reactions (rash, urticaria).

Serious

• Cardiovascular events (myocardial infarction, stroke) – rare but more likely in patients with pre‑existing severe cardiac disease.
• Vision loss due to non‑arteritic anterior ischemic optic neuropathy (NAION).
• Severe allergic reaction (anaphylaxis).

Clinically Relevant Drug–Drug Interactions

• Nitrates (e.g., glyceryl trinitrate, isosorbide dinitrate) – contraindicated; additive vasodilation may cause life‑threatening hypotension.
• Potent CYP3A4 inhibitors (ketoconazole, itraconazole, ritonavir, clarithromycin) – increase sildenafil plasma levels; dose reduction recommended.
• CYP3A4 inducers (rifampin, carbamazepine, phenytoin) – decrease efficacy; consider alternative therapy.
• Alpha‑blockers (tamsulosin, doxazosin) – may cause additive blood pressure lowering; start with the lowest sildenafil dose and monitor.
• Other PDE5 inhibitors – concurrent use is not advised due to overlapping mechanisms and increased toxicity risk.

Patients should disclose all current medications, including over‑the‑counter products and herbal supplements, before starting Sildigra.

Practical Use: Dosing, Missed Dose, Overdose

• Standard starting dose for ED: 50 mg taken as a single tablet, approximately 30 minutes to 1 hour before anticipated sexual activity. Depending on efficacy and tolerability, the dose may be adjusted to 25 mg (for patients requiring a lower dose) or 100 mg (maximum recommended dose). The medication may be taken with or without food; a high‑fat meal can delay onset by up to 2 hours.

• Maximum frequency: No more than one dose per 24‑hour period.

• Pulmonary arterial hypertension dosing (off‑label): Typically 20 mg taken three times daily, spaced evenly (e.g., 8 am, 2 pm, 8 pm). This lower, scheduled regimen differs from the as‑needed ED dosing.

• Missed dose: If a dose is forgotten and the individual is not sexually active for the next 24 hours, the dose should be discarded. Do not double the next dose.

• Overdose: Symptoms may include severe headache, dizziness, hypotension, prolonged erection, or visual disturbances. If an overdose is suspected, seek immediate medical attention; supportive care (intravenous fluids, blood pressure monitoring) is the primary treatment.

• Precautions:

  • Avoid excessive alcohol, which can exacerbate hypotension and dizziness.
  • Patients with cardiovascular disease should undergo an exercise stress test before initiating therapy to confirm they can tolerate sexual activity.
  • Renal or hepatic impairment may require dose reduction; consult a physician for individualized guidance.

FAQ

• Is Sildigra available in both brand‑name and generic forms in Hong Kong?
  Yes. The brand‑name product Viagra® contains the same active ingredient, sildenafil citrate, as Sildigra. The generic formulation provides identical therapeutic effects at a lower cost, making it a popular choice for many patients.

• What is the optimal way to store Sildigra tablets?
  Store the tablets at room temperature (15–30 °C) in a dry place, away from direct sunlight, moisture, and heat sources. Keep the container tightly closed and out of reach of children.

• Can I travel with Sildigra on an international flight?
  Yes. Carry the medication in its original packaging with a clear label, and retain a copy of the prescription or a doctor's note if requested by customs. It is advisable to keep the tablets in hand luggage to avoid temperature extremes in the cargo hold.

• Does the formulation of Sildigra differ between regions such as the US, EU, and Asia?
  The active ingredient (sildenafil citrate) and its dosage strengths are consistent worldwide. Inert excipients may vary slightly to meet local regulatory guidelines, but these differences do not affect the drug’s efficacy or safety profile.

• Are there any specific warnings for Asian populations using sildenafil?
  Pharmacokinetic studies suggest that Asian patients may experience slightly higher plasma concentrations at equivalent doses, potentially increasing the incidence of mild side effects such as headache or flushing. Starting at the lower 25 mg dose is often recommended, with titration based on tolerance.

• Can Sildigra be safely imported for personal use in Hong Kong?
  Personal import of a 30‑day supply of prescription medicines for personal use is permitted under Hong Kong regulations, provided the medication is for a legitimate medical condition and the patient holds a valid prescription. Our online pharmacy assists with compliant import documentation.

• What should I do if I experience a painful erection lasting more than four hours?
  This condition, known as priapism, is a medical emergency. Seek immediate care at the nearest Accident & Emergency department. Timely treatment is essential to prevent permanent penile tissue damage.

• Does Sildigra interact with common over‑the‑counter supplements such as ginseng or L‑arginine?
  Herbal supplements that influence nitric‑oxide pathways (e.g., ginseng, yohimbine) may theoretically augment sildenafil’s vasodilatory effect, increasing the risk of hypotension. Discuss any supplement use with a healthcare professional before starting therapy.

• How does the cost of Sildigra compare with brand‑name Viagra in Hong Kong?
  Generic sildenafil typically costs 30–60 % less per tablet than the branded counterpart, depending on the dosage strength and retail outlet. Purchasing from our online pharmacy further reduces cost due to bulk sourcing and minimized overhead.

• Is there any risk of failing a drug test after taking Sildigra?
  Standard workplace drug screening panels do not include sildenafil, as it is not a controlled substance. However, a comprehensive toxicology screen could detect the compound if specifically requested.

• What is the difference between Sildigra’s use for erectile dysfunction and for pulmonary arterial hypertension?
  For ED, sildenafil is taken on an “as‑needed” basis at higher doses (25–100 mg) shortly before sexual activity. For PAH, it is prescribed at lower, scheduled doses (typically 20 mg three times daily) to maintain steady plasma concentrations that lower pulmonary artery pressure.

Glossary

Phosphodiesterase‑5 (PDE5) Inhibitor

A class of drugs that block the PDE5 enzyme, preventing breakdown of cyclic guanosine monophosphate (cGMP) and thereby promoting smooth‑muscle relaxation and increased blood flow.

cGMP (Cyclic Guanosine Monophosphate)

A second messenger molecule that mediates vascular smooth‑muscle relaxation; its levels rise after nitric‑oxide activation and are sustained by PDE5 inhibition.

Priapism

A prolonged, often painful erection lasting more than four hours, unrelated to sexual stimulation, requiring urgent medical treatment to prevent tissue damage.

Hypotension

An abnormally low blood pressure, which can cause dizziness, fainting, or shock if severe; sildenafil can lower blood pressure especially when combined with other vasodilators.
