When a man is sexually aroused, the arteries in the penis relax and widen, allowing more blood to flow into the erectile tissue. At the same time, the veins that usually drain blood from the penis are compressed, trapping blood within the erectile tissue, resulting in an erection. However, in men with ED, this process is disrupted due to various factors such as underlying health conditions or psychological issues.
Sildenafil citrate in Cenforce 50mg works by inhibiting the action of PDE5, an enzyme that breaks down a chemical called cyclic guanosine monophosphate (cGMP). cGMP is responsible for relaxing the smooth muscles in the arteries of the penis, allowing them to dilate and increase blood flow. By inhibiting PDE5, sildenafil helps to maintain higher levels of cGMP, promoting stronger and longer-lasting erections.
