Erectile Dysfunction (ED)

Cialis Generic vs Brand



Have there been any studies on the effectiveness of generic tadalafil vs the brand named Cialis? If so what are the results?


I have to say there is none that I am aware of. The patent limit has not expired for the drug. Therefore, there should not be any generic available. However, other countries beside USA have tried to manufacture and sell the generic form without the pharmaceuticals' permission, which is against the FDA and US laws.
