Vigora 50 mg, works by increasing blood flow to the penis during sexual stimulation. It achieves this by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which is responsible for the degradation of cyclic guanosine monophosphate (cGMP). By inhibiting PDE5, sildenafil allows cGMP to accumulate, promoting smooth muscle relaxation in the penile arteries and corpus cavernosum. This, in turn, leads to increased blood flow to the penis, facilitating an erection.
