Who May Take Viagra?

Erectile dysfunction is most commonly found in older men. Most cases of impotence in this group have a physical basis. Viagra is prescribed to these men so that they can have sufficient erections for peak sexual performance. Viagra has its limitations and may not be effective in all cases. It is important for you to understand that:

It is not an aphrodisiac - it cannot cause a person to become aroused when the person is not interested or when the sexual stimulation is missing
It is not a performance-enhancing drug
It will not give faster or harder erections in healthy people who do not suffer with erectile problems
In fact, in healthy men Viagra use can result in a painful, long-lasting erection (priapism), which itself could lead to an erectile dysfunction
It does not have the ability to raise low testosterone levels
It cannot increase your sexual appetite or make you ejaculate if you have problems reaching orgasm
It will in not correct hormonal abnormalities

Sildenafil is the active ingredient in Viagra; a first in a new class of medicines called phosphodiesterase type-5 (PDE5) inhibitors.

The drug enhances blood flow to the penis by selectively blocking the PDE5 enzyme, which is responsible for the break down of cyclic guanosine monophosphate (cGMP).

The cGMP allows for smooth blood flow to the penis. The good part about sildenafil is that it does not embarrass men by causing an erection on its own; only sildenafil in the presence of sexual stimulation can cause an erection to occur. This also means that Viagra blue pill is not an aphrodisiac.

Sildenafil is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5). Sildenafil helps relax the muscles in the penis, resulting in increased blood flow and consequently an erection. Used for the treatment of male impotence, sildenafil potentiates the hypotensive effects of nitrates.
