Erectile dysfunction (ED) is one of the conditions that can be treated with the highly effective medication Vidalista 20mg.  tadalafil is the active ingredient in Vidalista 20mg, a Phosphodiesterase Type-5 (PDE-5) inhibitor.  Vidalista , manufactured by Fortune Healthcare, is widely available in the US. 

 Blood flow to the penile area is increased by Vidalista .  It contains tadalafil, which works by stopping the PDE-5 enzymes from breaking down cyclic guanosine monophosphate (cGMP).  This inhibition improves blood circulation by raising cGMP levels.  Consequently, increased blood flow facilitates the development and maintenance of an erection.
