Citando:
"Packs of eight tablets of Viagra - also called sildenafil - would be made available, with men told to take no more than one tablet per day.
Viagra, which works by relaxing blood vessels, thereby allowing blood to flow to the penis, works for about eight hours and is designed to be used "on demand".
Erectile dysfunction can be caused by a range of conditions, including psychological problems, but can also be a sign of underlying heart disease, diabetes or high blood pressure."
