Fildena 150 mg is a highly effective treatment for erectile dysfunction, featuring a substantial dose of sildenafil citrate. It works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which regulates blood flow in the penile. By blocking PDE5, Fildena 150 mg enhances the levels of cyclic guanosine monophosphate (cGMP), leading to the relaxation of smooth muscle cells and increased blood flow to the penile tissues. This process helps achieve and maintain a firm erection during sexual activity. Its effectiveness is particularly notable in individuals who require a higher dosage for optimal results, offering a reliable solution for improved sexual performance and confidence.
