Fildena Professional works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). PDE5 is responsible for breaking down cyclic GMP, a molecule that helps relax the blood vessels in the penis. By blocking PDE5, Fildena Professional allows cyclic GMP to accumulate, leading to improved blood flow and, consequently, better erectile function. This mechanism of action is similar to that of other PDE5 inhibitors, but Fildena Professional is noted for its extended duration of action and faster onset time. One of the main advantages of Fildena Professional is its extended duration of effect. Unlike some other ED medications that may last for a few hours, Fildena Professional provides a more prolonged impact, which can enhance sexual spontaneity and satisfaction.
