Filitra 20 Mg is a medication that contains the active ingredient vardenafil, a phosphodiesterase type 5 (PDE5) inhibitor. PDE5 is an enzyme that can restrict blood flow to the penis, which is one of the primary causes of erectile dysfunction. By inhibiting PDE5, vardenafil helps relax the blood vessels, allowing for increased blood flow to the penis. This improved circulation enables men to achieve and maintain an erection during sexual activity. While the physical effects of Filitra 20 Mg are the main focus, the medication also has indirect benefits for mental health.
