Le Sildenafil 50 mg est l’un des traitements les plus couramment prescrits pour traiter la dysfonction érectile (DE). Ce médicament, connu sous son nom commercial Viagra et d’autres formes génériques, offre une solution efficace pour les hommes qui rencontrent des difficultés à obtenir ou à maintenir une érection suffisante pour des rapports sexuels satisfaisants. Mais comment fonctionne exactement le Sildenafil 50 mg, et combien de temps ses effets durent-ils ? Décryptons ensemble ces questions essentielles.

The mechanism of action of Sildenafil

Le Sildenafil appartient à une classe de médicaments appelés inhibiteurs de la phosphodiestérase de type 5 (PDE5). Pour comprendre son mode d’action, il est utile d’examiner ce qui se passe dans le corps lors d’une érection.

When a man is sexually aroused, the brain sends nerve signals that stimulate the release of nitric oxide (NO) into the erectile tissue of the penis. Nitric oxide activates an enzyme that produces cyclic guanosine monophosphate (cGMP). This molecule plays a crucial role in relaxing the smooth muscles of the blood vessels in the penis, allowing an influx of blood that causes an erection.

However, in some men, PDE5 breaks down cGMP quickly, which prevents the maintenance of an erection. Sildenafil works by inhibiting this enzyme, thereby prolonging the action of cGMP and facilitating a sustained erection.

When and how should Sildenafil 50 mg be taken?

Le Sildenafil 50 mg est habituellement pris environ 30 à 60 minutes avant l’activité sexuelle. Il est important de noter que ce médicament ne provoque pas une érection spontanée. Une stimulation sexuelle est nécessaire pour que le médicament soit efficace.

Here are some tips to optimize its effects:

  • Take the tablet with a glass of water.
  • Avoid meals high in fat, as they can slow down absorption and delay the effects.
  • Limit alcohol consumption, which can reduce the effectiveness of the medication.

The recommended initial dose is 50 mg, but it can be adjusted to 25 mg or 100 mg depending on the patient's response and the doctor's advice.

What is the duration of effect of Sildenafil 50 mg?

Once ingested, Sildenafil typically starts to work within 30 to 60 minutes, although this can vary from one person to another. The maximum effect is reached about one hour after ingestion.

The duration of Sildenafil's effect is on average 4 to 6 hours. This means that a man can respond to sexual stimulation during this period. However, it is important to understand that the medication does not cause a continuous erection: the penis returns to a flaccid state after ejaculation or in the absence of stimulation.

Factors influencing duration and effectiveness

Several factors can influence the duration and effectiveness of Sildenafil 50 mg:

  1. Age: Older men may metabolize the drug more slowly, prolonging its effects.
  2. Health status: Conditions such as diabetes, cardiovascular diseases, or obesity can reduce effectiveness.
  3. Concomitant medications: Certain medications, such as nitrates, may interact with Sildenafil and are therefore contraindicated.
  4. Alcohol and food consumption: Alcohol and heavy meals can decrease or delay the effects.

The potential side effects

Like any medication, Sildenafil can cause side effects. The most common include:

  • Headaches
  • Facial redness
  • Digestive troubles
  • Nasal congestion
  • Transient visual disturbances (bluish vision or blurred vision)

These effects are usually mild and go away on their own. However, in the case of prolonged erection (erections lasting more than 4 hours, called priapism) or serious side effects, it is essential to consult a doctor immediately.

The importance of a medical prescription

Although Sildenafil is an effective and widely used treatment, it is not suitable for everyone. A medical consultation is essential for:

  • Assess your overall health and identify any potential contraindications.
  • Prescribe the appropriate dose.
  • Ensure the safety of your treatment.

Platforms like kano.care offer online medical consultations with certified doctors, allowing you to get a prescription discreetly and safely.

Alternatives to Sildenafil

Besides Sildenafil, other medications are available to treat erectile dysfunction, including Tadalafil (Cialis) and Vardenafil (Levitra). These medications differ in their duration of action and characteristics, which allows for finding an option suited to each individual. A healthcare professional can guide you in choosing the most appropriate treatment.

Sildenafil 50 mg is an effective solution for men suffering from erectile dysfunction. By inhibiting the PDE5 enzyme, it promotes better blood flow in the penis and helps to improve the quality of erections. With an effective duration of 4 to 6 hours, this medication aids in regaining a fulfilling sexual life. However, a medical consultation is imperative to obtain this type of treatment.

What medication should be taken to achieve an erection?

Erectile dysfunction affects many men at different times in their lives. Whether related to stress, fatigue, medical or psychological causes, it can have a significant impact on self-confidence and quality of life. Faced with this issue, many seek medicinal solutions to achieve a satisfactory erection. However, it is essential to remember that only treatments prescribed by a doctor after a consultation are acceptable. Self-medication or purchasing drugs from unapproved sites can be dangerous to health.

Medicinal treatments such as Viagra and Cialis, available through Kano.care, offer an immediate and scientifically validated solution, unlike dietary supplements which remain unproven.

Medication vs Dietary Supplement for better erections.

In a market flooded with solutions for erectile dysfunction, it is essential to distinguish truly effective treatments from products that are at best supplementary, at worst ineffective. The difference between a medication and a dietary supplement is crucial, as it directly affects the health and effectiveness of the proposed solutions. At Kano, we have chosen to offer our patients access to approved medicinal treatments prescribed by health professionals, thus ensuring optimal and effective management of erectile dysfunction.

Viagra is an effective medication for erectile dysfunction, but its use must be supervised by a healthcare professional. Indeed, improper use can lead to serious side effects and dangerous interactions.

How to buy Viagra? (or Sildenafil)

Viagra is a medication used to treat erectile dysfunction, but unlike other products that are freely available, it cannot be purchased directly from a pharmacy or online without a prescription.
