Fildena 150 mg is effective in treating ED caused by various factors, including physical and psychological issues. It helps improve erectile function and enhances sexual performance. Sildenafil citrate in Fildena 150 mg works by inhibiting the enzyme PDE5, which regulates blood flow in the penis. By blocking PDE5, sildenafil increases levels of cyclic guanosine monophosphate (cGMP), a chemical that relaxes smooth muscles in the blood vessels of the penis.
