I have a question about the different isomers of methylphenidate.
Is it the case that the "L" isomer, which is absent in focalin (but compromises 50% of Ritalin) is primarily peripherally acting whereas the "D" isomer (100% Focalin, 50% Ritalin) is mostly centrally active?
In other words, are the isomers analogous to amphetamine in terms of their biological activity?
I cannot tolerate the cardiovascular effects of regular Ritalin (or Adderall or Dexedrine) and wonder if Focalin would really present an advantage over it.
