Vidalista 80 pills aid to sustain an erection during sexual activity or intercourse. They are used to treat male dysfunction difficulties or impotence problems.
Tadalafil is a member of the PDE5 inhibitors drug class. By blocking PDE5, it prevents the breakdown of cGMP in the penis, which is how it treats erectile dysfunction.
An erection is produced by increased blood flow due to smooth muscle relaxation brought on by elevated cGMP levels.

When a man is stimulated sexually, Vidalista helps him get and sustain an erection. It does not, however, improve a man's libido or treat erectile dysfunction.
