Description: 

Sildenafi 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 Viagras 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 Viagras 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 Viagras 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 Viagras use.

Application: 

Sildenafi citrate, sold as Viagras, Revatio and under various other trade names, is a drug used to treat erectile dysfunction and pulmonary arterial hypertension (PAH).used in the treatment of penile erectile dysfunction (ED).

The primary indication of sildenafi is treatment of erectile dysfunction (inability to sustain a satisfactory erection to complete intercourse). Its use is now standard treatment for erectile dysfunction in all settings, including diabetes.People on antidepressants may experience sexual dysfunction, either as a result of their illness or as a result of their treatment.

In 16 separate 4-24 week trials of men (over 18 years old) who suffered from impotence for longer than 6 months, dosages between 10-200 mgs were administered. Significant improvements in erectile function, including frequency of penetration as well as erection duration post penetration, were reported with Sildenfi* treatment compared to the placebo group.
Erections were improved in 72% of group verses 18% of the placebo group. In all cases effects were dependant upon dosage and improvement was the greatest when dosage exceeded 100 mgs. Responses were decreased by 40-60% in patients suffering from diabetes and prostatectomy, respectively. Withdrawal rates were less than 5% related to negative side effects and limited response rates
