What may not seem like alot on paper sometimes does not translate that way in terms of clinical effects on people. Lots of people respond better to adderall than Dexedrine, the only difference is that Adderall contains DL amphetamine, where as Dexedrine is D amphetamine.
Same thing for Celexa and Lexapro.
