Viagra, also known as sildenafil, is a medication used to treat erectile dysfunction (ED) in men. ED is a common condition where a man is unable to achieve or maintain an erection during sexual activity. Viagra works by increasing blood flow to the penis, which helps men achieve and maintain an erection.

What is Viagra?

Viagra is a brand name for the medication sildenafil. It was first approved by the Food and Drug Administration (FDA) in 1998. Sildenafil is a type of medication called a phosphodiesterase type 5 (PDE5) inhibitor. This means that it works by blocking the enzyme PDE5, which is responsible for breaking down a substance called cyclic guanosine monophosphate (cGMP) in the body. When PDE5 is blocked, cGMP is not broken down, and this helps to increase blood flow to the penis.

How does Viagra work?

Viagra works by increasing blood flow to the penis. When a man is sexually aroused, the body releases a chemical called nitric oxide. Nitric oxide helps to relax the blood vessels in the penis, which allows more blood to flow into the area. Sildenafil helps to increase the amount of nitric oxide in the body, which helps to further relax the blood vessels in the penis. This increased blood flow helps men achieve and maintain an erection.

How much Viagra can I take?

The recommended starting dose of Viagra is 50 mg. This dose can be increased or decreased based on the individual's response to the medication. It is important to note that Viagra should not be taken more than once a day. It is also important to talk to your healthcare provider before taking Viagra, as it may not be safe for everyone. Certain medical conditions or medications may interact with Viagra, so it is important to discuss any potential risks with your healthcare provider.
