The Tale On Viagra, Cialis and Levitra

The Viagra, Cialis and Levitra story makes interesting reading. Viagra is the first FDA (Food and Drugs Administration) approved medicine to treat erectile dysfunction and after Viagracare yielded a tremendous amount of success in treating men suffering from ED or the inability to facilitate erections essential for sexual intercourse, Cialis and Levitra entered the pharmaceutical market and successfully cured thousands of men from the grip of impotence.

The saga on Viagra and other erectile dysfunction medicines that I have started is not concocted but is an honest and wholly true account on the anti-impotence drugs. In continuation to this tale, let me inform you that similarly to Viagra, Cialis and Levitra have also been approved by the FDA as effective treatments of erectile dysfunction in men. These three medicines Viagra, Cialis and Levitra start functioning by inhibiting the PDE5 (phosphodiesterase type 5) enzyme and facilitating the effects of nitric oxide. And as soon as Viagra or Cialis or Levitra restricts the action of PDE5 enzyme and increases the functioning process of nitric oxide, blood flows to the penis smoothly and in an unhindered way and this further makes the penis capable of facilitating erections essential for sexual intercourse.
