Edegra is one of the most popular forms of generic Viagra which has sildenafil citrate as its key ingredients. Sildenafil citrate is basically a vasodilator which expands the size of the arteries and allows the male reproductive organ to swell up due to sudden rush of blood and also sustain the swelling (erection) for a long duration which enables the man to have penetrative intercourse. Physiologically this is performed due to inhibition of an enzyme called as PDE5 (phosphodiesterase type 5) which arrests the action of cGMP (Cyclic guanosine monophosphate). PDE5 does not allow the blood to circulate in the pelvic region due to which the male reproductive organ does not get the required blood to become erect.
Besides effectively treating erectile dysfunction, sildenafil citrate (Edegra) also holds the potential to treat other medical conditions such as muscular dystrophy, cardiovascular disorders and cancer (in combination with other drugs). Various clinical researches are under way to study the hidden potential of Edegra.
