Viagra, Niagra (niagara falls)

[eduser_admin]

Does anyone know where the name Viagra actual came from was it from Niagara falls or Niagra falls. I heard that a long time ago but am not sure if it is true. They same they named it Viagra because Niagra falls is a powerful water and that represents a powerful erection?
