How can a person respond better to ritalin than concerta for example or the opposit , if the 2 are from the same generic :methylphenidate ?

Generic concerta: When going from one generic to another you may find differences in blood levels attained due to differences in absorption because the pills or capsules are made differently and contain different fillers that can effect the extent of and rate of absorption. This can result in your system getting 20% more or less approximately compared to the brand name drug.

Different forms: Ritalin is the older immediate-acting form of methylphenidate - you take it and the contents are released. Concerta is a long-acting formulation, meaning you take the tablet and the drug is slowly released over 12 hours. The result is a longer duration of action, but lower peak levels of the drug. Depending on your symptoms, side effects, ; your lifestyle, one or the other may be more ideal.
