The basic ingredient of Viagra is Sildenafil. These drugs are little diamond-shaped and blue colored oral pills available in several dosages – 25mg, 50mg, and 100mg.
Viagra relaxes the blood vessels of a patient thus drawing blood to the stimulated organ – penis. This way an erection is built. However, Viagra won’t affect on its own. Tactile, visual or any other sexual stimulation is a must for having an erection.
Generally, sildenafil gets absorbed in the body very quickly. Young men can get an erection as soon as in twelve minutes after receiving the medication, while for others it might take up to seventy minutes (usually for elderly men).
However, the average time necessary for experiencing the effect of Viagra is twenty-seven minutes. This statement was studied and proved by the British Journal of Clinical Pharmacology.
