Sildenafil Citrate is solely active in relaxing muscles and increasing blood flow to the heart, lungs and penis due to PDE-5, yet vasodilation is not increased in other parts of the body.
Technical Data: In studies where Viagra was administered to over 3700 patients, 19-87 years old in world wide clinical trials. More than 550 patients received treatment post 1 year. 2.5% of the Viagra subjects and 2.3% of the placebo subjects reported adverse effects, which were all considered mild. These reported side effects included abnormal or blurred vision and increased sensitivity to light.
All other negative reactions reported, including URI, flu symptoms, back pain and arthralgia, occurred at a rate of less than 2% and equally common in the placebo and Viagra administered groups. Effects worsened and were reported more frequently as dosages increased.
Other studies measured duration of sexually stimulated erection using a Rigiscan device. Duration of rigidity was increased by 60% with Viagra use.
