VIAGRA

Viagra (sildenafil citrate) works as an oral therapy for erectile dysfunction by increasing blood flow to the penis. In men with erectile dysfunction blood flow to the penis is insufficient to allow for an erection that lasts long enough for sexual intercourse. By improving blood flow to the penis Viagra lets men experience normal sexual excitation and ejaculation. buy viagra online

CIALIS

In 2003, Cialis (tadalafil) became the third medication in a class of medications known as PDE5 (phosphodiesterase type 5) inhibitors to be approved for the treatment of erectile dysfunction. Erectile dysfunction is a condition in which blood flow to the penis is restricted, causing an inability for the penis to fill with blood, keeping the penis from hardening or causing an erection to fade earlier than desired. Cialis works by dilating blood vessels that feed the penis, allowing for adequate blood fill. order cialis now

LEVITRA

Erectile dysfunction is a problem for millions of men at some point in their lives. This treatable medical condition results in strain on relationships, low self esteem and self-destructive tendencies. Until 1998, there were no proven treatments for ED. However, since that time medications under the classification of PDE5 (phosphodiesterase type 5) inhibitors have meant a revolution in male sexual health. In 2003, the FDA approved vardenafil, under the name Levitra, for the treatment of erectile dysfunction. Levitra works to increase blood flow to the penis, allowing for an erection that lasts long enough for sexual activity. Those men who were previously unable to take other ED medications or who experienced little or no benefit from those medications may find that Levitra works for them. Those with diabetes, high blood pressure or high cholesterol often respond favorably to Levitra. purchase levitra
