Sildenafil in Clinical Studies
“Effect of sildenafil on ventilatory efficiency and exercise tolerance in pulmonary hypertension” by Ronald J. Oudiz et al is a study in which the use of sildenafil in improving the exercise tolerance and the ventilator efficiency in people was assessed. These people were diagnosed with pulmonary arterial hypertension and a consequent pulmonary vasculopathy. This pulmonary vasculopathy results in an enhanced resistance towards the flow of blood in the lungs. It also ensures a limitation of the cardiac output which is required to increase the demands of oxygen during exercise. In this study, the physiological basis of the treatment of pulmonary arterial hypertension was checked by administering sildenafil in them. It was hypothesized that an improvement in the ventilator efficiency and the flow of blood towards the lungs serve as the key factors in this improvement. Improvement in these factors would lead to an improved exercise capacity as well as the oxygen pulse over time. 28 patients suffering from pulmonary arterial hypertension were selected for this study. Out of these 28 patients, 14 were given sildenafil while the rest of the 14 patients were assessed without administering any sildenafil in them. All of the patients were given a treatment with warfarin as well as diuretics. 13 out of 14 patients who were being given sildenafil were also being treated with drugs for the treatment of pulmonary arterial hypertension. These patients were asked to indulge in a cardiopulmonary exercise both before as well as after the treatment. All of the parameters via which the patients were assessed were found to be improved in the patients who were being treated with sildenafil while there was a worsening seen in those who did not receive any sildenafil. It was concluded that the condition of patients suffering from pulmonary arterial hypertension improved by the administration of sildenafil. 
“Treatment of erectile dysfunction with sildenafil “by Leonard S Marks focused on all the aspects of treating an episode of erectile dysfunction with sildenafil. The main objective was to check the level of effectiveness of sildenafil in a clinical setting in the patients suffering from erectile dysfunction. The perceptions of the patients and their partners about the treatment were also correlated in this study. The severity of the erectile dysfunction and the level of response generated by the patient were also linked. A hundred men were selected in this study who were given sildenafil out of which 74 people completed the questionnaire given to them about their sexual health i.e. International Index of Erectile Function (IIEF). This questionnaire was given to them both before and after treating them with sildenafil for about 4 to 6 weeks. The same questionnaire was slightly modified and was given to the partners of these patients to fill. The disease of erectile dysfunction in these patients was categorized into 4 categories according to the severity. According to the question 3 and 4 of the IIEF, about 71 percent to 95 percent improvement was recorded in the erections of the patients consuming sildenafil. 77 percent of the total people wished to continue the treatment when the test trial was over. The score of the patients was compared with the results of the questionnaire filled up by their partners. It was seen that people suffering from class 1 erection problem responded much more as compared to those who did not achieve erections at all and were included in class 4. Patients who underwent a prostatectomy were refractory to sildenafil treatment. It was concluded from the questionnaire response that sildenafil is a great remedy for getting rid of erectile dysfunction. 
How Sildenafil Works
Sildenafil is a potent inhibitor of the famous enzyme- PDE5. This enzyme acts to work on the chemical messenger called as cGMP. PDE5 breaks down cGMP into phosphates and guanosine. As sildenafil is the potent inhibitor of PDE5, the levels of cGMP in specific areas increase which leads to the enhanced and prolonged action of this chemical messenger. cGMP acts on the smooth muscles of the penile arteries and acts on it to cause to strong vasodilating effect. As the vessels dilate, the blood to the penile organ is increased leading to stronger and prolonged erection. This erection stays as long as sildenafil remains in the blood. 
Napifit Benefits for Erectile Dysfunction
Napifit has sildenafil citrate which is a powerful agent for the fight against erectile dysfunction.

Premature ejaculation can be stopped and reaching the climax is made easy. Napifit can also be used to treat a condition of hypertension throughout the body due to its dilating action on the vessels.
