Viagra - facts and myths about its operation

Viagra, or indeed the active substance sildenafil, was invented by Pfizer's medical experts. In the first years of the existence of this preparation, its high price made viagra one of the most frequently counterfeited medicines in the world.

Viagra is a medicine for men who experience problems with normal erection. It contains a chemical compound that improves the flow of blood to the genitals. Interestingly, the effectiveness of viagra was discovered accidentally. Initially, sildenafil was intended for angina pectoris and hypertension. It soon became apparent that the clinical results were not so satisfactory for these diseases. Sildenafil was patented in 1996 and sold two years later under the name Viagra.
