Cenforce Professional

Introduction

Cenforce Professional is a tablet containing the phosphodiesterase‑5 (PDE5) inhibitor sildenafil. It is prescribed for the treatment of erectile dysfunction (ED) and is classified within men’s health medicines. In Hong Kong the drug is available only with a valid medical prescription and is regulated by the Department of Health. Sildenafil, the active compound, facilitates the physiological process that leads to erection when sexual stimulation occurs. Although its primary indication is ED, the drug is also used off‑label for pulmonary arterial hypertension under a different dosage regimen.

What is Cenforce Professional?

Cenforce Professional is a generic formulation of sildenafil citrate. The medication is produced by a range of manufacturers that specialise in generic erectile‑dysfunction therapy; exact origin varies by batch but all comply with Good Manufacturing Practice (GMP) standards required by international health authorities.

It contains the same 100 mg dose of sildenafil as the well‑known brand Viagra® (Pfizer) and other approved generics. Our online pharmacy provides this generic alternative as a cost‑effective treatment option for men who meet the clinical criteria for sildenafil therapy.

How Cenforce Professional Works

Sildenafil selectively inhibits the enzyme phosphodiesterase‑5 (PDE5) that degrades cyclic guanosine monophosphate (cGMP) in the smooth muscle of the corpus cavernosum. Sexual arousal releases nitric oxide (NO), which stimulates guanylate cyclase to increase cGMP levels. Elevated cGMP relaxes smooth muscle, allowing inflow of blood and erection. By blocking PDE5, sildenafil prolongs cGMP activity, enhancing the natural erectile response.

Typical onset of action occurs within 30–60 minutes after oral ingestion, with a clinical effect lasting up to 4–6 hours. The drug is metabolised principally by hepatic CYP3A4 and CYP2C9 enzymes; the elimination half‑life is approximately 4 hours, after which it is excreted mainly in the urine. Food, especially high‑fat meals, can delay absorption and modestly reduce peak plasma concentrations.

Conditions Treated with Cenforce Professional

• Erectile Dysfunction (ED) – The primary, FDA‑ and HKHA‑approved indication. ED prevalence in Hong Kong is estimated at 15 %–20 % of men aged 40 years and older, reflecting both physiological and psychosocial contributors.
• Pulmonary Arterial Hypertension (PAH) – Sildenafil is approved at lower doses (20 mg three times daily) for PAH, improving exercise capacity and haemodynamic parameters. This indication is not the typical use of the 100 mg “Professional” strength and requires specialist supervision.

The drug’s efficacy in ED is supported by numerous randomized controlled trials, demonstrating significant improvement in International Index of Erectile Function (IIEF) scores compared with placebo.

Patient Groups Most Likely to Benefit

• Men aged 18 – 65 years with diagnosed organic or psychogenic erectile dysfunction who have normal cardiovascular status.
• Patients with diabetes mellitus who experience endothelial dysfunction, a common cause of ED; sildenafil improves penile blood flow without affecting glycaemic control.
• Individuals on stable antihypertensive therapy (excluding nitrates) who experience medication‑related erectile issues; sildenafil is generally safe with most blood‑pressure agents.
• Patients with PAH under specialist care, using the lower dosage regimen.

Contra‑indications include men taking nitrates (e.g., nitroglycerin), those with severe uncontrolled hypertension (>185/120 mmHg), recent history of stroke or myocardial infarction (<6 weeks), or those with known hypersensitivity to sildenafil or any tablet excipients.

Risks, Side Effects, and Interactions

Common

• Headache
• Flushing (warmth or redness of face, neck, or chest)
• Nasal congestion or rhinitis
• Dyspepsia (indigestion)
• Visual disturbances (blurred vision, a blue‑tinted hue)

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

Rare

• Priapism (prolonged erection > 4 hours) – requires emergency treatment to prevent permanent tissue damage.
• Sudden hearing loss or tinnitus.
• Severe hypotension, especially when combined with other vasodilators.

Serious

• Cardiovascular events (myocardial infarction, stroke) in patients with pre‑existing unstable cardiac disease.
• Severe allergic reactions (anaphylaxis) manifesting as rash, swelling, airway compromise.
• Vision loss due to non‑arteritic anterior ischemic optic neuropathy (NAION).

Drug–Drug Interactions

• Nitrates (e.g., isosorbide dinitrate, nitroglycerin) – co‑administration can cause profound hypotension; contraindicated.
• Alpha‑blockers (e.g., tamsulosin) – may increase the risk of symptomatic hypotension; dose adjustment and careful monitoring are advised.
• CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin, ritonavir) – can raise sildenafil plasma concentrations, potentially intensifying side effects; dose reduction may be necessary.
• CYP3A4 inducers (e.g., rifampicin, carbamazepine) – may lower efficacy; consider alternative therapy.

Patients should disclose all prescription, over‑the‑counter, and herbal products to the evaluating clinician.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing – The typical starting dose for ED is 50 mg taken as needed, approximately one hour before anticipated sexual activity. Depending on efficacy and tolerability, the dose may be increased to 100 mg or reduced to 25 mg. The maximum recommended frequency is once per 24 hours.
• Missed dose – If a dose is forgotten, it should be taken only when sexual activity is anticipated. If the scheduled time is within 4 hours of the next planned dose, skip the missed tablet to avoid exceeding the daily maximum.
• Overdose – Symptoms may include severe headache, hypotension, prolonged erection, or visual changes. Immediate medical attention is advised. Management is supportive; there is no specific antidote.
• Food and alcohol – A high‑fat meal may delay onset; moderate alcohol consumption is permissible but excessive intake can increase the risk of hypotension and dizziness.
• Comorbidities – Patients with severe renal or hepatic impairment require dose adjustment (often 25 mg).

FAQ

• What is the difference between Cenforce Professional and the original brand Viagra?
  Cenforce Professional contains the same active ingredient, sildenafil citrate, at the same strength as Viagra. The formulation, bioavailability, and clinical effect are equivalent, but the generic version is typically less expensive because it does not carry the brand‑name premium.

• How should Cenforce Professional be stored to maintain potency?
  The tablets should be kept at room temperature, between 15 °C and 30 °C, away from direct sunlight, moisture, and heat sources. Do not store in bathrooms or near kitchen stoves, as humidity and temperature fluctuations can degrade the medication.

• Can I import Cenforce Professional for personal use in Hong Kong?
  Personal import of prescription medicines is permissible if the product is accompanied by a valid Hong Kong prescription and meets the standards of the Department of Health. Our online pharmacy assists customers by ensuring the medication complies with import regulations and provides the necessary documentation for customs clearance.

• Is it safe to take Cenforce Professional with antihypertensive drugs?
  Sildenafil can be used concurrently with most blood‑pressure medications, such as ACE inhibitors, beta‑blockers, and calcium channel blockers. However, when combined with alpha‑blockers or nitrate therapy, the risk of symptomatic hypotension increases and requires medical supervision.

• How long does it take for Cenforce Professional to work after taking a dose?
  On average, the onset of erectile response occurs within 30 to 60 minutes. Eating a heavy, high‑fat meal may delay absorption, extending the time to effect by up to 2 hours.

• What should I do if I experience a prolonged erection lasting more than four hours?
  A sustained erection (priapism) is a medical emergency. Seek immediate care at the nearest emergency department or call an ambulance. Prompt treatment is essential to prevent permanent penile tissue damage.

• Does the dosage need to be adjusted for older adults?
  For men aged 65 years and older, a lower starting dose of 25 mg is often recommended to minimise side‑effects, especially if the individual has comorbidities such as renal or hepatic impairment. Dose titration should be guided by a health professional.

• Can Cenforce Professional be used as part of a telemedicine treatment plan?
  Yes. Licensed telemedicine providers in Hong Kong can evaluate eligibility, prescribe sildenafil, and coordinate delivery through our online pharmacy. The virtual consultation must include a thorough medical history and assessment of contraindications.

• Do I need a prescription to buy Cenforce Professional in Hong Kong?
  Purchasing Cenforce Professional from a local pharmacy in Hong Kong requires a valid prescription from a qualified healthcare professional. Our online service streamlines this requirement. Every order undergoes a mandatory professional evaluation conducted by an independent, licensed healthcare professional who assesses the health information provided by the customer during checkout. The purpose is to ensure the medication is both safe and medically appropriate for the individual. If the reviewing professional requires more detail to make a safe assessment, our care team will contact the customer to clarify the necessary information. This process upholds the highest standards of patient safety while facilitating convenient access.

• How can I verify the authenticity of the tablets I receive?
  Authentic Cenforce Professional tablets bear a batch number, expiry date, and manufacturer’s imprint on each pill. Our pharmacy provides a QR code on the packaging that links to an online verification portal where the batch details can be cross‑checked with the supplier’s database.

• Are there any specific warnings for Asian populations taking sildenafil?
  Clinical studies have not identified ethnicity‑specific safety concerns for sildenafil. However, some Asian patients may have a higher prevalence of concomitant use of herbal supplements (e.g., ginkgo biloba) that could potentiate bleeding risk when combined with nitrate therapy. Patients should disclose all complementary medicines to the evaluating clinician.
