A miserable sexual life can easily set off erectile dysfunction. Opt for something that tastes much better and is not only much more affordable than the brand-name Viagra (which costs a lot more than the generic form of sildenafil citrate). The unmatched efficacy of Filitra is accompanied by improved patient compliance. Blood flow to the penile area is correlated with male penile erection. An increase in blood flow to the smooth muscles leads to their relaxation and eventual erection of the penis. This is how an erection happens. 

The cavernous body, or portion of the penis, releases nitric oxide during sexual stimulation. This leads to an increase in the synthesis of cyclic guanosine monophosphate, which in turn increases blood flow to the penile area and relaxes the smooth muscles. When their penis fails to harden during sexual stimulation, many older men experience difficulties achieving a penile erection. They are consequently unable to engage in appropriate sexual activity. An erection of the penis results from this relaxation of the smooth muscles. In this mechanism, an enzyme known as phosphodiesterase enzyme 5 (PDE 5) functions as a feedback regulator. Consequently, there is no long-lasting erection because cyclic GMP in the penis eventually breaks down. A specific inhibitor of phosphodiesterase type 5 is called Filitra and Cipla Suhagra.
