what vivance is is D amphetamine only but in time release form and Vyvanse was actually developed as a way to try and get around or rather prevent some of the abuse potential of Adderall and Other Drugs that contain damphetamine D amphetamine stands for dextra amphetamine and in the 70s and 80s there were a fair amount of movies and there was a lot of trafficking and there was a lot of criminal activity related to what was called dexedrine dexedrine is pure D amphetamine so if we're going to be very direct if I were going to just frame these things in the context of their neurochemistry what I can tell you is that vivance is time release dexedrine it's not time release Adderall
