In a healthy person, increased blood circulation in the penile area during sexual excitation results in an erection.
However, there are a number of reasons why blood does not flow into the penis during sexual stimulation, such as unhealthy lifestyle choices, smoking, and excessive alcohol use. Consequently, there isn't an erection.
Filagra tablets belong to the class of PDE5 inhibitors. The role of PDE5 is to inhibit the activity of the cyclic guanosine monophosphate (cGMP) enzyme.
CGMP is responsible for the smoothing of the muscles in erectile dysfunction, which increases blood vessels in the penis and facilitates erection.
