Fildena 150 mg contains Sildenafil, the same active ingredient found in Viagra. It works by inhibiting the PDE5 enzyme, which breaks down cGMP, a molecule responsible for relaxing the smooth muscles in the blood vessels of the penis. By blocking this enzyme, Fildena allows cGMP to accumulate, leading to the relaxation of these muscles and increased blood flow to the penis, which facilitates an erection. However, it’s important to note that Fildena only works in the presence of sexual stimulation.
