Viagra, scientifically known as sildenafil citrate, is one of the most recognized prescription medications in the world. Primarily used to treat erectile dysfunction (ED) in 비아그라 구매, Viagra has transformed conversations around men’s health, bringing once-taboo topics into the mainstream with a more open, informed, and respectful approach.
What is Viagra?
Viagra is a PDE5 inhibitor, meaning it works by relaxing the blood vessels in the body, particularly in the genital area. This enhances blood flow to the penis when a man is sexually aroused, making it easier to achieve and maintain an erection.
Viagra does not increase sexual desire and is not an aphrodisiac. It only helps those who experience difficulty achieving an erection due to medical or psychological reasons.
Originally developed to treat high blood pressure and angina, its effects on erectile function were discovered during clinical trials, leading to its approval for ED treatment in 1998 by the U.S. Food and Drug Administration (FDA).
How Does Viagra Work?
Viagra typically begins to work within 30 to 60 minutes after ingestion and remains effective for up to 4 hours. However, it does not cause an erection without sexual stimulation. It’s most effective when taken on an empty stomach and not combined with alcohol or fatty meals.
The key mechanism involves the inhibition of the enzyme phosphodiesterase type 5 (PDE5), which allows for increased levels of cyclic GMP, a molecule that promotes muscle relaxation and blood flow in the penis.
Who Can Use Viagra?
Viagra is usually prescribed to men with diagnosed erectile dysfunction, which may stem from various causes such as:
- Diabetes
- Heart disease
- High blood pressure
- Stress and anxiety
- Hormonal imbalances
- Side effects of certain medications
Viagra is not recommended for individuals who take nitrates for chest pain, have certain heart or liver conditions, or are advised against sexual activity due to health risks.

Cultural Impact and Myths
Since its introduction, Viagra has had a profound cultural and social impact. It changed how men’s sexual health is discussed publicly and paved the way for more open conversations about aging, relationships, and self-confidence.
However, it also became the subject of many myths:
- Myth: Viagra causes instant, uncontrollable erections.
Fact: It only works with sexual stimulation. - Myth: It’s only for older men.

- Psychological therapy for anxiety-related ED
- Lifestyle changes: quitting smoking, reducing alcohol, improving diet and exercise
In many cases, combining treatment with lifestyle improvements produces the best results.
Conclusion
