Action Mechanisam of Sildenafil Citrate
The major reason behind erectile dysfunction is the less blood flowing to the male organ. Sildenafil citrate is used to correct the blood flow. As mentioned earlier health issues, penile surgery or stress affects blood flowing to the male organ. Another reason for the same is the effect of an enzyme named PDE5 on the arteries. This enzyme affects the smooth cell lining of arteries and constricts them. This is how blood flow gets reduced.
Sildenafil citrate works on this enzyme. It blocks it successfully to reduce its concentration in the penile area. On the hander it also increases the level of cyclic GMP which relaxes the blood vessels. Because of this chemical, these arteries become flexible and wide enough to carry blood. More blood reaches to the male organ within short time span. This is how sildenafil citrate helps in gaining tight and firm erection.
This whole process of blocking the PDE5 enzyme and augmenting cyclic GMP in the penile region takes few minutes. To initiate the procedure, erotic stimulation is needed. That is why after consuming sildenafil citrate, getting involved in the carnal activity is needed. Erection develop by the pill remain for longer time span. It stays for four hours.
