Fildena 100 mg is a potency enhancer and the dick harder that comprises of Sildenafil Citrate, inhibitor PDE5 (phosphodiesterase type 5). When a man is sexually excited Nitric oxide (NO) is released on corpus cavernosum penis.

This promotes the synthesis of cyclic guanosine monophosphate (cGMP), which calms soft tissue and widens blood vessels to enhance blood flow during a firm penis.

Instead of cGMP being broken down by PDE5, sildenafil interferes with PDE5 thus allowing cGMP to be longer utilized by the tissues in the penis. In blocking this enzyme, Fildena makes sure that cGMP stays for longer, thus improving erectile functioning and maintaining an erection when sexually stimulated.
