Not exact.: Ritalin is the brand name for methylphenidate (mph), and Adderall (dextroamphetamine and racemic amphetamine) is the brand name for amphetamine (amp). Mph is about half as potent as d-amp, so 20 mg of methylphenidate would be roughly 10 mg of d-amp. But, Adderall (dextroamphetamine and racemic amphetamine) is a mix of d- and l-amp, and only d-amp is active; so, the ritalin/adderall ratio is more like 20/15. As dr. Hoffman said: little, especially adding in individual differences.

What are the similarities and differences between Adderall / metadate / ritalin (methylphenidate) / concerta?

MPH vs DA, Timing: Those medications differ in two major ways. First, whether they are a methylphenidate (mph) base like ritalin, metadate, or concerta, or whether they are Dextroamphetamine based like adderall (dextroamphetamine and racemic amphetamine). Individual benefits and side effect profiles are based largely on this distinction. The second difference is in timeframe as all these medications can operate in the body in differing timecourses.

Inside, outside: Ritalin (methylphenidate) goes into brain cells and stops them from taking up dopamine and norepi, which are associated with focus, motivation and pleasure. That increases the amount of them in the space between cells. Adderall does the same thing. It also, however, goes inside cells and makes them pump out dopamine. It not only blocks the reuptake of the substance but also acts to increase its levels directly.
