Genegra Information

Introduction

Genegra contains the phosphodiesterase‑5 (PDE5) inhibitor sildenafil and is classified for the treatment of erectile dysfunction (ED) and related aspects of men’s health. In Hong Kong, sildenafil‑based therapy is widely prescribed for men who experience difficulty achieving or maintaining an erection sufficient for sexual activity. The medication is manufactured by a licensed pharmaceutical firm (specific manufacturer details may vary by supplier) and is marketed under the generic name Genegra. In addition to its primary indication, sildenafil is sometimes used off‑label for pulmonary arterial hypertension, though Genegra is not approved for that purpose in Hong Kong.

What is Genegra?

• Classification – Genegra is a prescription‑only oral tablet belonging to the PDE5 inhibitor class.
• Active ingredient – Each tablet contains sildenafil citrate, the same molecule found in well‑known brand names such as Viagra® and Revatio®.
• Development – Sildenafil was first approved by the U.S. Food and Drug Administration (FDA) in 1998 for erectile dysfunction. Generic formulations like Genegra were introduced after the original patents expired, providing a cost‑effective alternative.
• Manufacturer – The specific manufacturer may differ depending on the source, but all approved versions must meet the quality standards set by the Hong Kong Pharmacy and Poisons Board.

How Genegra Works

Sildenafil selectively blocks the enzyme phosphodiesterase‑5, which normally degrades cyclic guanosine monophosphate (cG ​c) in the smooth muscle of the corpus cavernosum. By inhibiting PDE5, sildenafil allows cG ​c to accumulate, leading to relaxation of the smooth muscle and increased blood flow into the penis during sexual stimulation.

Key pharmacologic points:

• Onset – Oral absorption typically yields peak plasma concentrations within 30–120 minutes; many men notice an effect within 30–60 minutes.
• Duration – The therapeutic effect can last up to 4–6 hours, although individual responses vary.
• Metabolism and clearance – Sildenafil is metabolised primarily by hepatic CYP3A4 and CYP2C9 enzymes; the average elimination half‑life is about 4 hours. Renal excretion accounts for ~13 % of the dose.

Conditions Treated with Genegra

• Erectile Dysfunction (ED) – The principal approved indication. In Hong Kong, epidemiological surveys estimate that 10–15 % of men aged 40–70 experience some degree of ED, making sildenafil‑based therapy a common clinical need.
• Male Sexual Dysfunction secondary to Diabetes or Cardiovascular disease – Sildenafil is effective in men whose ED is linked to endothelial dysfunction, a common pathway in these chronic conditions.
• Other off‑label uses (not approved in Hong Kong) – Pulmonary arterial hypertension (PAH) and certain cases of benign prostatic hyperplasia (BPH) have been investigated, but Genegra is not marketed for these indications locally.

Is Genegra the Right Medication for You?

• Suitable candidates – Adult men (≥18 years) who have a confirmed diagnosis of erectile dysfunction and who have no contraindications to PDE5 inhibition. Patients with stable cardiovascular disease, controlled hypertension, or diabetes often benefit from sildenafil when lifestyle measures alone are insufficient.
• Clinical scenarios where Genegra is favored –
  • Intermittent sexual activity where a short‑acting agent is preferred.
  • Men who require a medication that does not require nightly dosing.
  • Individuals seeking a more affordable option compared with brand‑name Viagra® in Hong Kong.
• Contra‑indications – Patients taking nitrates (e.g., nitroglycerin), those with severe hypotension (systolic < 90 mmHg), recent history of non‑arteritic anterior ischemic optic neuropathy (NAION), or known hypersensitivity to sildenafil or any tablet excipients should avoid Genegra.

Risks, Side Effects, and Interactions

Common

• Headache
• Facial flushing
• Dyspepsia or indigestion
• Nasal congestion
• Visual disturbances (e.g., a blue‑tinted color perception)

Rare

• Priapism (prolonged erection lasting > 4 hours)
• Sudden hearing loss
• Severe hypotension, especially when combined with alpha‑blockers

Serious

• Cardiovascular events (myocardial infarction, stroke) in patients with existing high‑risk cardiac disease – although causality is not definitively established, caution is advised.
• Non‑arteritic anterior ischemic optic neuropathy (NAION) – rare but potentially irreversible vision loss.

Drug–Drug Interactions

• Nitrates (e.g., nitroglycerin, isosorbide dinitrate) – concurrent use can cause marked hypotension.
• CYP3A4 inhibitors (e.g., ketoconazole, erythromycin, protease inhibitors) – may increase sildenafil plasma levels, raising the risk of side effects. Dose reduction is recommended.
• CYP3A4 inducers (e.g., rifampin, carbamazepine) – can lower sildenafil exposure, potentially reducing efficacy.
• Alpha‑blockers (e.g., tamsulosin) – additive blood‑pressure‑lowering effect; start with low sildenafil doses and monitor.

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

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing – The usual starting dose for most men is 50 mg taken as a single tablet about one hour before sexual activity. Depending on efficacy and tolerability, the dose may be adjusted to 25 mg or increased to a maximum of 100 mg. The tablet should be taken with water; food may delay onset but does not affect overall effectiveness.
• Special populations –
  • Elderly (≥65 years) or patients with moderate hepatic impairment may start at 25 mg.
  • Renal impairment (creatinine clearance < 30 mL/min) also warrants a lower initial dose.
• Missed dose – Because Genegra is taken only when sexual activity is anticipated, a missed dose simply means the patient did not take the tablet prior to intercourse. Do not take an additional dose later in the day to “make up” for the missed one.
• Overdose – Symptoms may include severe hypotension, dizziness, prolonged erection, or visual changes. If overdose is suspected, seek immediate medical attention. Supportive care (e.g., fluid resuscitation, blood pressure monitoring) is the mainstay of treatment; there is no specific antidote.

FAQ

• What is the typical appearance of a Genegra tablet?
  Genegra tablets are usually round, film‑coated, and may appear blue or white depending on the manufacturer’s specification. The imprint often includes the dosage strength (e.g., “25 mg” or “50 mg”) and a manufacturer code.

• Can Genegra be stored in a refrigerator during Hong Kong’s hot summer months?
  No special cooling is required. Genegra should be kept at room temperature (15‑30 °C) away from excess heat, humidity, and direct sunlight. A refrigerator is unnecessary and could cause condensation on the tablets.

• Is it safe to travel internationally with Genegra in my carry‑on luggage?
  , provided the medication is in its original packaging with a clear label. Carry a copy of the prescription or a physician’s note if requested by customs authorities. Keep the tablets in a sealed container to prevent breakage.

• Does Genegra contain any allergens such as lactose or gluten?
  In most formulations, the inactive ingredients include microcrystalline cellulose, magnesium stearate, and lactose. Patients with severe lactose intolerance should check the specific batch’s excipient list supplied by our pharmacy before use.

• Will Genegra show up on routine drug tests for employment or sports screening?
  Sildenafil is not typically included in standard occupational or anti‑doping screens because it is not a prohibited performance‑enhancing substance. However, some specialized panels may detect it if specifically requested.

• Are there any differences between Genegra produced for the Asian market versus the European market?
  The active ingredient (sildenafil) is identical, but tablet size, colour, and certain excipients can vary by region to meet local regulatory preferences. Both formulations deliver the same therapeutic dose.

• Can Genegra be taken with grapefruit juice?
  Grapefruit juice inhibits CYP3A4, potentially increasing sildenafil plasma concentrations and the risk of side effects. It is advisable to avoid large amounts of grapefruit juice around the time of dosing.

• What are the legal requirements for personal import of Genegra into Hong Kong?
  Hong Kong permits individuals to import a 30‑day supply of prescription medication for personal use, provided a valid prescription is retained. Our online pharmacy ensures compliance by shipping only the quantity requested and providing documentation for customs if needed.

• How long does it take for Genegra to reach its peak effect after ingestion?
  Peak plasma concentrations generally occur within 30 to 120 minutes. The onset of erection‑facilitating effects is usually observed within the first hour, though individual metabolism may influence timing.

• Is there any evidence that Genegra improves sexual satisfaction beyond erection quality?
  Clinical trials of sildenafil demonstrate improvements in overall sexual satisfaction scores, primarily because achieving a reliable erection reduces performance anxiety. No direct studies of the generic product exist, but the pharmacologic effect is the same as the brand‑name trials.
