Vilitra 60 is a medication that contains the active ingredient Vardenafil, which is primarily used to treat erectile dysfunction (ED) in men. It belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. To understand how buy vilitra 60 mg online works, it's important to first understand the physiological process behind an erection. During sexual stimulation, nitric oxide is released in the erectile tissue of the penis, which then activates an enzyme called guanylate cyclase. This enzyme increases the levels of a chemical called cyclic guanosine monophosphate (cGMP), leading to relaxation of the smooth muscles in the penile blood vessels. This relaxation allows increased blood flow into the penis, resulting in an erection.

In men with erectile dysfunction, the enzyme PDE5 breaks down cGMP, leading to a reduced ability to maintain an erection. Vilitra 60 inhibits the action of PDE5, which helps to increase the levels of cGMP in the erectile tissue. By doing so, Vilitra 60 promotes smooth muscle relaxation and enhances blood flow to the penis, enabling a firm and sustained erection during sexual stimulation.
