Filitra 40 Mg is a PDE5 inhibitor. That means it works by blocking the enzyme that breaks down cGMP, the chemical that relaxes blood vessels in the penis and allows blood to flow in. When this enzyme is blocked, more cGMP is available, and that means better erections. In a clinical study of men with erectile dysfunction, those who took Filitra 40 MG had significantly better erections than those who took a placebo. They also reported improved satisfaction with their sex lives.
