ADHD medication is an excellent example illustrating the potential "wiggle room" differences between generics and brand drugs. The composition is similar enough to meet FDA generic drug standards, but the rate at which the generic drug mechanisms distribute the drug differs and potentially decreases treatment efficacy for many patients. Though, I do wonder if Vyvanse becoming a generic brand will help solve this dilemma, because the release mechanism is tied closer to the individuals metabolism via hydrolysis of an amino acid rather than relying on release rates set by minor manufacturing differences.
