General Information about Viagra, Generic Viagra?

What is Viagra?

Viagra is an anti-impotence drug made by Pfizer with an active ingredient sildenafil citrate to treat male impotence. Sildenafil Citrate relaxes muscles and increases blood flow to certain areas of the body. The intake of Viagra increased the ability to achieve and maintain an erection when sexual stimulation. Men who Take Viagra have reported an amplified sex drive, increased endurance and faster recharge. Viagra works along with sexual stimulation to help achieve maximum sexual satisfaction. However, Viagra does not guarantee protection against STDs, including HIV and Hepatitis.

How Viagra works?

Viagra allows many men with ED to respond to sexual stimulation. When a man is sexually aroused, the arteries in the penis relax and widen, allowing more blood to flow into the penis. As the arteries in the penis expand and harden, the veins that normally carry blood from the penis become compressed, restricting the flow of blood from the penis. With more blood flowing in and less flowing out, the penis enlarges, resulting in an erection. It should be noted that Viagra is not a hormone or aphrodisiac, it only works when a man is sexually stimulated.

Viagra Dosage

Viagra is available in tablet form and is meant to be taken by mouth. Ideally, it took almost an hour before sexual activity. However, Viagra can be taken anytime from 4 hours to 30 minutes before sexual activity. It takes 30 to 45 minutes showing the effect of Viagra, and this effect lasts for almost four hours. If you take Viagra after a high-fat meal (such as fish and chips, cheeseburger or French fries) may take a little longer to start working. Viagra should not take more than once a day unless prescribed by your doctor.
