Penegra Information

Introduction

Penegra is a medication indicated for the treatment of erectile dysfunction (ED) in adult men. It contains the active compound sildenafil, a phosphodiesterase‑5 (PDE5) inhibitor that belongs to the therapeutic group of men’s health agents. In the United Kingdom, Penegra is supplied by a licensed manufacturer and is prescribed when a rapid, reliable response to sexual stimulation is required. The drug is also recognised for its secondary use in the management of pulmonary arterial hypertension under a different brand name (Revatio), although the primary indication in the UK market is erectile dysfunction.

What is Penegra?

Penegra is a tablet formulation that delivers a precise dose of sildenafil citrate. It is classified as a prescription‑only medicine (POM) within the UK’s Medicines and Healthcare products Regulatory Agency (MHRA) framework. The product was developed following the same clinical pathway as the original sildenafil brand, Viagra, and is manufactured by a company that complies with Good Manufacturing Practice (GMP) standards.

Penegra provides the identical pharmacological action as well‑known sildenafil products such as Viagra, Revatio, and other generic alternatives. It is marketed as a cost‑effective option for men seeking treatment of erectile dysfunction while maintaining the same safety and efficacy profile as the reference brands.

How Penegra Works

Sildenafil exerts its effect by selectively inhibiting the enzyme phosphodiesterase‑5 (PDE5) that is abundant in the smooth muscle of the corpus cavernosum. During sexual arousal, nitric oxide (NO) is released from nerve endings and endothelial cells, stimulating the production of cyclic guanosine monophosphate (cGMP). cGMP relaxes smooth‑muscle fibres, allowing increased blood flow into the penis and producing an erection.

By blocking PDE5, Penegra prevents the rapid degradation of cGMP, thereby prolonging smooth‑muscle relaxation and enhancing penile engorgement. Onset of action typically occurs within 30–60 minutes after oral intake, with the therapeutic effect lasting up to 4–6 hours. The drug is metabolised primarily by hepatic CYP3A4 and CYP2C9 enzymes, with an average elimination half‑life of 3–5 hours, allowing predictable clearance in most patients.

Conditions Treated with Penegra

• Erectile Dysfunction (ED): The principal indication, addressing the inability to achieve or maintain an erection sufficient for satisfactory sexual performance. In the UK, an estimated 1 in 10 men over 40 experience some degree of ED, highlighting the public‑health relevance of effective therapy.
• Pulmonary Arterial Hypertension (PAH) – off‑label reference: While not an approved indication for Penegra itself, the same active compound (sildenafil) is licensed as Revatio for PAH, illustrating the broader vascular actions of the molecule.

Penegra’s efficacy in ED has been confirmed by multiple randomized controlled trials that demonstrated statistically significant improvements in the International Index of Erectile Function (IIEF) scores compared with placebo.

Who is Penegra For?

Penegra is appropriate for adult men who:

• Have a documented diagnosis of erectile dysfunction and require pharmacological support to achieve satisfactory erections.
• Are able to take oral medication and have no contraindications related to cardiovascular disease, severe hepatic impairment, or medication interactions that affect CYP3A4 metabolism.
• Do not respond adequately to lifestyle modifications alone (e.g., exercise, weight control, smoking cessation).

Penegra is not recommended for:

• Women, children, or adolescents, as the safety profile has not been established in these groups.
• Men who have been advised against sexual activity due to unstable angina, recent myocardial infarction, or uncontrolled hypertension (>180/110 mmHg).
• Individuals using nitrate medications (e.g., nitroglycerin) because combined vasodilatory effects can cause dangerous hypotension.

Risks, Side Effects, and Interactions

Common

• Headache
• Facial flushing
• Dyspepsia (indigestion)
• Nasal congestion
• Vision changes (e.g., a blue tint to vision)

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

Rare

• Priapism (prolonged erection > 4 hours)
• Sudden hearing loss
• Myocardial ischemia in patients with pre‑existing coronary artery disease
• Severe hypotension

Patients experiencing any of these symptoms should seek prompt medical advice.

Serious

• Anaphylactic reaction (rare)
• Acute cardiac events (rare in high‑risk populations)
• Stroke (extremely rare)

If any serious adverse reaction is suspected, immediate emergency care is required.

Drug–Drug Interactions

• Nitrates (e.g., nitroglycerin, isosorbide dinitrate): additive vasodilation → severe hypotension.
• Alpha‑blockers (e.g., doxazosin, tamsulosin): may cause additive blood‑pressure lowering effects.
• CYP3A4 inhibitors (e.g., ketoconazole, ritonavir, clarithromycin): increase sildenafil plasma concentrations → higher risk of side effects.
• CYP3A4 inducers (e.g., rifampicin, carbamazepine): may reduce efficacy by lowering drug levels.

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

Practical Use: Dosing, Missed Dose, Overdose

• Standard Starting Dose: 50 mg taken as a single tablet approximately 30–60 minutes before anticipated sexual activity.
• Dose Adjustment: Based on efficacy and tolerability, the dose may be increased to 100 mg or decreased to 25 mg. The maximum recommended single dose is 100 mg, and the drug should not be taken more than once per 24‑hour period.
• Missed Dose: If a dose is forgotten, it should be taken as soon as the patient remembers, provided there is at least a 4‑hour interval before the next planned dose. If the timing is close to the next dose, the missed tablet should be omitted to avoid excessive dosing.
• Overdose Management: Acute overdose may present with severe hypotension, syncope, or prolonged erection. The patient should be monitored, and supportive measures (intravenous fluids, vasopressors) may be required. No specific antidote exists; care is symptomatic.

Practical Considerations

• Food: A high‑fat meal can delay onset of action by up to 2 hours; patients preferring rapid effect should take Penegra on an empty stomach or after a light meal.
• Alcohol: Moderate alcohol consumption does not significantly affect efficacy, but excessive intake may exacerbate hypotensive effects and diminish erectile response.
• Comorbidities: Patients with severe renal or hepatic impairment should use reduced doses (typically 25 mg) and be monitored closely.

FAQ

• Is Penegra available in both brand‑name and generic forms in the UK?
  Yes. Penegra is the generic form of the original sildenafil brand, Viagra. Both contain the same active ingredient and are regulated by the MHRA, but generic versions like Penegra are typically priced lower.

• What is the most appropriate way to store Penegra tablets?
  Store the tablets at room temperature (15–30 °C) in a dry place, away from direct sunlight, moisture, and heat sources. Do not keep them in bathrooms or near kitchen stoves.

• Can I travel internationally with Penegra in my luggage?
  When traveling, keep the medication in its original packaging with a clear label. Carry a copy of the prescription or a doctor’s letter if required by customs, and ensure the quantity does not exceed personal use limits.

• Does the appearance of Penegra tablets differ from other sildenafil products?
  Penegra tablets are usually round, blue‑coloured, and bear the dosage imprint (e.g., “50 mg”). Visual differences are minor, but imprint codes can be used to verify authenticity.

• Are there any specific warnings for men of Asian ancestry taking Penegra?
  Some pharmacokinetic studies indicate slightly higher plasma concentrations of sildenafil in certain Asian populations, which may increase the risk of side effects. Dose adjustment to 25 mg may be considered after professional review.

• How does Penegra’s formulation compare between the EU and US markets?
  The active ingredient (sildenafil citrate) is identical, but excipients such as fillers or binders may vary due to regional regulatory preferences. These differences do not affect the therapeutic outcome.

• Is it safe to use Penegra alongside antihypertensive medication?
  Generally, co‑administration is safe, but concurrent use of strong vasodilators (e.g., nitrates or certain alpha‑blockers) can cause additive blood‑pressure lowering. Blood pressure should be monitored, especially after the first dose.

• What impact does grapefruit juice have on Penegra’s effectiveness?
  Grapefruit juice inhibits CYP3A4, potentially increasing sildenafil plasma levels and the likelihood of side effects. It is advisable to avoid large quantities of grapefruit products around the time of dosing.

• Can Penegra be imported for personal use without a UK prescription?
  Personal importation of prescription medicines into the UK is permitted when the product is for personal use, the quantity does not exceed three months’ supply, and a valid prescription is provided. Importing without a prescription may breach customs regulations.

• What clinical trials established the efficacy of sildenafil for erectile dysfunction?
  Large‑scale, double‑blind, placebo‑controlled trials conducted in the 199s demonstrated that sildenafil significantly improved IIEF scores compared with placebo. These studies formed the basis for regulatory approval worldwide.

• Does Penegra have any effect on fertility or sperm quality?
  Current evidence shows that sildenafil does not adversely affect sperm parameters or male fertility when used at therapeutic doses for erectile dysfunction.
