Tadalafil, an inhibitor of phosphodiesterase type 5 (PDE5), is the ingredient in Vidalista 40 mg tablets. It is a well-known first-line medication for erectile dysfunction that works by increasing blood flow to the penile region, therefore improving erectile function.

It functions by preventing PDE-5, an enzyme that reduces cyclic guanosine monophosphate (cGMP), from doing its job. It's a substance that opens blood vessels and relaxes smooth muscles. A hard erection is achieved by inhibiting PDE-5, which causes the blood vessels in the penis to relax and enhance blood flow.

But in order for Vidalista 40 mg to be effective, sexual stimulation must still occur. It does not start sexual arousal.
