Viagra or sildenafil is a prescription-only medication that is indicated for the treatment of impotence of erectile dysfunction in men. In essence, Viagra is actually the brand name of sildenafil citrate. Sildenafil is a category of drug that is used to help men gain and maintain an erection that is good enough to engage in penetrative sex.

Viagra works by improving the blood flow to the penile region whenever a man experiences sexual stimulation. In essence, it helps men to get and keep an erection. There are many alternatives of Viagra including Cialis, Stendar, and Levitra. They all work in a similar manner, but Viagra is known to be the most effective and safest of all ED prescription-only medication.

In the even that a man is sexually stimulated, his brain then transmits signals to the muscle cells in his penis to relax. This said chemical reaction increases the blood flow to the penile region, thus stimulating an erection. Erectile dysfunction occurs when this process is disrupted as a result of physical or psychological factors.

Viagra makes sure that the process of erection works normally. It does this by causing the muscles in the penile region to relax which in turn improves blood flow, thus increasing the chances of getting an erection. Although this is the case, men should understand that Viagra is not an aphrodisiac, and should never be used as one. In order for Viagra to work, sexual arousal should be introduced.
