A generic drug called Vidalista 40 is used to treat erectile dysfunction. It is less expensive than the name-brand drug Cialis. Tadalafil, a medication classified as a phosphodiesterase type 5 (PDE5) inhibitor, is its active component.
PDE5 inhibitors function by stopping cyclic guanosine monophosphate (cGMP) from breaking down. The body produces cGMP when it is stimulated sexually. It causes the blood arteries in the penis to relax, which increases blood flow and results in an erection. Both a generic version of this 40 mg Tadalafil and the brand-name drug Cialis are accessible.
