The basic ingredient of the medicine is selective inhibitor of phosphodiesterase of 5th type of Sildenafil citrate. This substance relaxes smooth muscles of cavernous bodies of a penis and strengthens blood circulation in it. This causes erection. Useful properties of the active substance related to impotence therapy were revealed accidentally.

In 1992 in England scientists developed a new medicine against coronary heart disease on basis of Sildenafil. However the substance didn't strengthen blood circulation in the heart. However, one very interesting “collateral” effect was found in Sildenafil – it improved blood circulation in a penis and caused erection.

Original Viagra was produced in the form of diamond tablets with bluish-blue color an an inscription “Pfizer” on the one side, and with the figures corresponding to a dosage in mg (VGR 25, 50 or 100) on the other side. Besides, analogs of this remedy are available in the form of tablets, capsules and even gel.
