Vilitra 60 (which contains the active ingredient vardenafil) works by increasing blood flow to the ***** to help achieve and maintain an erection. However, it does not cause an erection on its own—it needs ***** stimulation to trigger the natural release of nitric oxide in your body. Here’s why: ***** stimulation activates nerves that release nitric oxide in the erectile tissue. Nitric oxide then increases levels of cGMP, a chemical that relaxes smooth muscles and allows blood vessels in the ***** to widen. This increased blood flow leads to an erection. Vilitra 60 helps maintain this process by blocking the enzyme PDE5, which breaks down cGMP. By preventing the breakdown of cGMP, Vilitra enhances and prolongs the erection process, but it can’t initiate it without ***** arousal. So, in short, Vilitra 60 enhances your body’s natural response to ***** stimulation but won’t cause an erection without it.
