Generic Cobra-120 Information

Introduction

Cobra-120 is a phosphodiesterase‑5 (PDE5) inhibitor indicated for the treatment of erectile dysfunction (ED) in adult men. The medication contains the active compound sildenafil, which belongs to the men’s‑health therapeutic group. In Hong Kong, erectile dysfunction affects a significant proportion of the male population, with prevalence estimates ranging from 10 % to 30 % in men aged 40 years and older (Hong Kong Department of Health, 2022). Cobra‑120 provides a pharmacologic option to restore erectile function, improve sexual confidence, and enhance quality of life for those affected.

What is Cobra‑120?

Cobra‑120 is a tablet formulated with 25 mg, 50 mg, or 100 mg of sildenafil citrate. It is manufactured by a licensed pharmaceutical company that adheres to Good Manufacturing Practice (GMP) standards; the specific producer is disclosed on the product label when ordered.

Sildenafil was originally developed by Pfizer and marketed worldwide under the brand name Viagra®. Other well‑known brand equivalents include Revatio® (approved for pulmonary arterial hypertension) and numerous authorized generics. Cobra‑120 is a generic version containing the same active ingredient, identical dosage strength, and comparable bioavailability to the reference products, offering a lower‑cost alternative for patients in Hong Kong.

How Cobra‑120 Works

Sildenafil selectively inhibits the enzyme phosphodiesterase‑5 (PDE5) that degrades cyclic guanosine monophosphate (cGMP) in the corpus cavernosum of the penis. During sexual stimulation, nitric oxide (NO) released from endothelial cells activates guanylate cyclase, leading to elevated cGMP levels. cGMP causes smooth‑muscle relaxation and arterial inflow, producing an erection. By blocking PDE5, sildenafil prolongs the action of cGMP, facilitating and sustaining erection when sexual arousal occurs.

Key pharmacokinetic points:

• Onset: 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: Primarily hepatic (via CYP3A4), with a half‑life of ≈ 4 hours; renal excretion accounts for ~ 15 % of clearance.

Conditions Treated with Cobra‑120

• Erectile Dysfunction (ED): Primary indication. Sildenafil improves the ability to achieve satisfactory penetration during sexual activity.
• Pulmonary Arterial Hypertension (PAH) – off‑label: Some clinicians prescribe sildenafil for PAH based on its vasodilatory properties, though Revatio® is the licensed product for this use.

In Hong Kong, ED is frequently under‑reported due to cultural sensitivities, making accessible treatment options like Cobra‑120 essential for public health.

Patient Groups Most Likely to Benefit

• Men aged 40 – 70 years experiencing organic or psychogenic ED.
• Patients with comorbidities such as diabetes mellitus, hypertension, or hyperlipidaemia, where endothelial dysfunction contributes to erectile problems.
• Individuals seeking a reversible, on‑demand therapy rather than continuous hormonal or surgical interventions.

Contra‑indications and cautionary groups:

• Men using nitrates (e.g., nitroglycerin) for angina—concurrent use can cause severe hypotension.
• Patients with severe uncontrolled hypertension (> 180/110 mmHg) or recent myocardial infarction (within 6 weeks).
• Individuals with significant hepatic impairment (Child‑Pugh class C) where drug metabolism is markedly reduced.

Risks, Side Effects, and Interactions

Common

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

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

Rare

• Priapism (erection lasting > 4 hours) – requires emergency treatment to prevent tissue damage.
• Sudden hearing loss or tinnitus.
• Severe hypotension, especially when combined with alpha‑blockers.

Serious

• Cardiovascular events (myocardial infarction, stroke) in patients with pre‑existing heart disease.
• Life‑threatening allergic reactions (anaphylaxis, angioedema).

Clinically Relevant Drug Interactions

• Nitrates (e.g., isoamyl nitrite, nitroglycerin): additive vasodilation → profound hypotension.
• Alpha‑blockers (e.g., tamsulosin, doxazosin): may cause additive blood pressure reduction; initiate sildenafil at the lowest dose and monitor.
• CYP3A4 inhibitors (e.g., ketoconazole, ritonavir): increase sildenafil plasma levels → higher risk of adverse effects; dose reduction recommended.
• CYP3A4 inducers (e.g., rifampicin, carbamazepine): may reduce efficacy; consider alternative therapy.

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

Practical Use: Dosing, Missed Dose, Overdose

• Starting dose: 50 mg taken as needed, approximately one hour before sexual activity.
• Dose adjustment: Based on efficacy and tolerability, the dose may be increased to 100 mg or decreased to 25 mg. Do not exceed one tablet per 24 hours.
• Food effect: A high‑fat meal can delay absorption and reduce peak concentration by up to 30 %; light meals are preferred.
• Alcohol: Moderate consumption is acceptable, but excessive alcohol can impair erection and increase side‑effect risk.

Missed dose: Sildenafil is not a scheduled daily medication. If a dose is missed, simply wait until the next planned sexual activity; do not take an extra tablet to “make up” for the missed dose.

Overdose: Symptoms may include severe hypotension, prolonged erection, or dizziness. Seek immediate medical attention. In a clinical setting, supportive measures (intravenous fluids, vasopressors) are employed; there is no specific antidote.

FAQ

• Is Cobra‑120 covered by Hong Kong’s public health insurance schemes?
  No, the Hospital Authority’s public drug formulary does not currently include sildenafil for erectile dysfunction, so the medication must be obtained privately. Our online pharmacy offers a price‑competitive alternative that many patients choose when insurance coverage is unavailable.

• Can Cobra‑120 be taken with antihypertensive medications?
  Generally, sildenafil can be combined with most antihypertensives without major issues. However, concurrent use with nitrates or certain alpha‑blockers may cause significant blood‑pressure drops. Always discuss your full medication list with a healthcare professional before starting treatment.

• What is the recommended storage condition for Cobra‑120 tablets?
  Store the tablets at room temperature (15 °C–30 °C), in a dry place away from direct sunlight, heat, and moisture. Do not keep them in bathrooms or near kitchen sinks where humidity is high.

• How long does a typical shipment from our online pharmacy take to arrive in Hong Kong?
  Express delivery usually reaches most districts within 7 days, while standard airmail may require up to 3 weeks, depending on customs processing. Tracking information is provided for all orders.

• Are there differences in formulation between Asian‑market sildenafil and Western versions?
  The active ingredient, sildenafil citrate, is chemically identical worldwide. Excipients may vary slightly to meet regional regulatory requirements, but these differences do not affect efficacy or safety when the product complies with GMP standards.

• Can women use Cobra‑120 for any medical condition?
  Sildenafil is not approved for use in women, and clinical data on efficacy for female sexual arousal disorder remain inconclusive. Women should seek alternative therapies under medical guidance.

• Is it safe to import Cobra‑120 for personal use in Hong Kong?
  Importation of prescription medicines for personal use is permissible if the drug is for a legitimate medical purpose and a valid prescription is obtained. Our service ensures each order is reviewed by a licensed healthcare professional, meeting local regulatory expectations.

• Does Cobra‑120 interact with herbal supplements such as ginkgo biloba?
  Ginkgo biloba has mild antiplatelet activity and may theoretically increase bleeding risk when combined with drugs that affect vascular tone. While no direct interaction with sildenafil has been firmly established, it is prudent to inform your clinician about any herbal products you use.

• What should I do if I experience a painful erection lasting more than four hours?
  A prolonged erection (priapism) is a medical emergency. Seek immediate care at the nearest emergency department. Early treatment reduces the risk of permanent penile tissue damage.

  What is required to obtain Cobra‑120 legally in Hong Kong?
