Cenforce 100, with its active ingredient Sildenafil Citrate, works by inhibiting the enzyme PDE5 in the body. PDE5 is responsible for breaking down a chemical called cGMP, which plays a crucial role in regulating blood flow. By inhibiting PDE5, Cenforce helps increase the levels of cGMP, leading to the relaxation of the smooth muscles in the blood vessels.
In cases of ED, this increased blood flow to the penile region enables a man to achieve and sustain an erection during sexual stimulation. For PAH, the dilation of blood vessels in the lungs reduces the workload on the heart and improves exercise capacity.
