Vega Extra Cobra Red 120 — High-strength Sildenafil (120 mg) for Erectile Dysfunction
What it is
Vega Extra Cobra Red 120 is a film-coated oral tablet containing 120 mg of Sildenafil (as Sildenafil Citrate), un selectivo inhibidor de la PDE5 utilizado para el tratamiento de disfunción eréctil (DE). It is intended for adult men and should be taken only under medical supervision, especially because 120 mg exceeds the typical maximum labeled dose of 100 mg used in many regions. Higher strength may increase the likelihood of adverse effects and drug–drug interactions.
How it works (mechanism)
Sexual stimulation triggers nitric-oxide release in penile tissue → ↑ cGMP → smooth-muscle relaxation and increased arterial inflow. Sildenafil selectively inhibits phosphodiesterase-5 (PDE5), the enzyme that degrades cGMP, thereby amplifying the body’s natural erectile response during sexual stimulation. Sildenafil is not an aphrodisiac and does not work without sexual arousal.
Onset, duration & food effect
- Inicio: typically 30–60 min; some individuals respond by ~25–30 min.
- Peak effect: ~60–120 min.
- Duración: up to 4–6 hours of improved erectile response (individual variability applies).
- Heavy/high-fat meals can delay onset and reduce peak effect; best on an empty stomach or after a light meal.
- Alcohol may impair erectile function and increase side effects (dizziness, hypotension).
Pharmacokinetics (class data)
- Absorción: t_max ~1 h (food may delay).
- Metabolismo: CYP3A4 (major) and CYP2C9 (minor).
- Elimination half-life: ~3–5 h.
- Excretion: mainly fecal; some renal as metabolites.
Who may benefit
- Adult men diagnosed with disfunción eréctil who have been deemed appropriate candidates for PDE5 inhibitor therapy by a clinician and who, after assessment, require a higher-strength option.
Dosage & administration
- Strength: 120 mg sildenafil per tablet.
- Use: Take 1 tablet as needed, approximately 30–60 minutes before sexual activity.
- Maximum frequency: Do not exceed 1 tablet in 24 hours.
- Because 120 mg is above common maximum dosing (100 mg), use only if specifically directed by a healthcare professional after assessing response and tolerability at lower doses (e.g., 25/50/100 mg).
- Swallow with water. Avoid grapefruit juice (CYP3A4 interaction).
Common side effects (dose-related)
- Dolor de cabeza, flushing, nasal congestion, dyspepsia, dizziness.
- Visual changes (blue/green tint, increased light sensitivity), blurred vision.
- Back pain/myalgia are less typical with sildenafil (more common with tadalafil) but can occur.
Less common/rare but serious
- Symptomatic hypotension, syncope (more likely with alcohol, dehydration, or interacting drugs).
- Priapism (erection >4 hours) — medical emergency.
- Sudden hearing loss o vision loss (NAION) — stop use and seek care.
- Cardiac events can occur in susceptible individuals engaging in sexual activity; medical screening is essential.
Contraindicaciones
- Nitratos (e.g., nitroglycerin, isosorbide) or nicorandil → severe, potentially life-threatening hypotension.
- Recent myocardial infarction or stroke, unstable angina, severe hypotension, severe heart failure (unless specifically cleared by a cardiologist).
- Insuficiencia hepática grave; significant renal impairment requires caution.
- Retinitis pigmentosa (rare hereditary retinal disorders).
- Known hypersensitivity to sildenafil or excipients.
Important drug interactions
- Potent CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, ritonavir, cobicistat, clarithromycin) can markedly increase sildenafil exposure → higher adverse-event risk; medical oversight is mandatory, and dose adjustments are usually required (often much lower than 100 mg).
- Alfabloqueantes (e.g., doxazosin, tamsulosin): risk of symptomatic hypotension — spacing of doses and careful titration advised.
- Otros inhibidores de la PDE5 o riociguat: avoid combination.
- Excess alcohol: increases dizziness/hypotension and can impair erectile performance.
Use & safety notes
- Not indicated for women or persons under 18.
- Avoid driving or hazardous tasks if dizzy or visually affected.
- If chest pain occurs during sexual activity, stop and seek medical help.
- If no effect after several separate uses, discuss with a clinician rather than increasing frequency or combining with other agents.
Storage & handling
- Store in a cool, dry place (15–30 °C), protected from light and moisture.
- Keep out of reach of children.
Quality & authenticity
- Ensure purchase from reputable suppliers. Packaging integrity, batch/lot numbers, and clearly labeled 120 mg sildenafil content help verify authenticity. Report suspicious products.
Resumen
Vega Extra Cobra Red 120 delivers single-agent Sildenafil at 120 mg for ED. Because this strength exceeds typical maximum dosing, it is suitable only when prescribed or approved by a healthcare professional after evaluating response to lower strengths and considering comorbidities, medications, and overall cardiovascular risk.
