By Viagra is a medication that has been on the market for over 20 years and has helped millions of men worldwide improve their sexual health. Originally developed as a treatment for high blood pressure, Viagra’s ability to improve erections quickly became its most famous use.
In this article, we’ll explore the history of 비아그라 구입, how it works, the benefits and side effects, and what to consider before using it.
The History of Viagra
Viagra was developed by Pfizer scientists in the 1990s. Initially, they were researching a new treatment for angina (chest pain), which is caused by inadequate blood flow to the heart. However, during clinical trials, they noticed that one of the side effects was improved erections in male participants.
After this discovery, Pfizer shifted its focus to developing the medication as a treatment for erectile dysfunction (ED). In 1998, the US Food and Drug Administration (FDA) approved Viagra as a treatment for ED, and it quickly became a blockbuster drug.
Today, Viagra is one of the most widely recognized prescription medications in the world, with millions of men taking it each year to improve their sexual health.
How Viagra Works
Viagra works by increasing blood flow to the penis. In men with ED, the blood vessels that supply the penis with blood become narrowed, which can make it difficult to achieve or maintain an erection.
Viagra contains an active ingredient called sildenafil citrate, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. When a man is sexually aroused, the body releases nitric oxide, which stimulates the production of cyclic guanosine monophosphate (cGMP), a chemical that relaxes the blood vessels in the penis and allows for increased blood flow.
However, in men with ED, the enzyme PDE5 breaks down cGMP too quickly, which can prevent the penis from becoming erect. Viagra works by inhibiting the action of PDE5, allowing cGMP to accumulate and promote the relaxation of the blood vessels in the penis.
Benefits of Viagra
The primary benefit of Viagra is that it can help men with ED achieve and maintain an erection suitable for sexual activity. In clinical trials, Viagra has been shown to improve erections in up to 80% of men with ED.
Beyond its use for ED, there is some evidence to suggest that Viagra may have other health benefits. For example, research has shown that it may improve exercise capacity in people with pulmonary hypertension, a condition that affects the blood vessels in the lungs.
Some studies have also suggested that Viagra may have potential as a treatment for various other conditions, including heart disease and certain types of cancer. However, more research is needed to fully understand these potential benefits.
Side Effects of Viagra

If you experience any of these severe side effects, you should seek medical attention immediately.
