How does Fildena 200 work to treat erectile dysfunction?

Fildena 200 is a medication primarily used to treat erectile dysfunction (ED), a condition where a man struggles to achieve or maintain an erection during sexual activity. It contains sildenafil citrate, a potent inhibitor of the enzyme phosphodiesterase type 5 (PDE5).

In ED, insufficient blood flow to the penis is often a key issue. When sexually stimulated, nitric oxide is released in the erectile tissue of the penis, which activates the enzyme guanylate cyclase. This enzyme increases levels of cyclic guanosine monophosphate (cGMP), causing the smooth muscles in the penile arteries to relax, allowing blood to flow into the penis and produce an erection.

However, PDE5 breaks down cGMP, leading to a decrease in blood flow and loss of erection. Fildena 200 and Vidalista 20 inhibits PDE5, allowing cGMP levels to remain elevated. This helps maintain the relaxation of smooth muscles in the penile arteries, promoting increased blood flow and facilitating erection.
