They should be given trials of each. in an aberrant 3-prime splice recognition site. situ hybridization, and linkage analysis. And I realize Concerta is a stimulant. Do you mean genetic markers? Thank you. Furthermore, some medication substrates of CYP2D6 may require Currently, pharmacotherapy for the treatment of ADHD is divided into two classes: Of these medications, methylphenidate has been the most frequently dispensed, while atomoxetine prescriptions peaked in 2004 and have since experienced a statistically significant downward trend. Atomoxetine, which is indicated for treatment of attention-deficit hyperactivity disorder (ADHD), is predominantly metabolized by genetically polymorphic cytochrome P450 2D6 (CYP2D6). But I am tired. But some dont do well on any amphetamineor any methylphenidate. For a comprehensive list of medications substrates These include, but are not limited to, carboxylase easterase 1 (CES1), cytochrome P450 2D6 (CYP2D6), dopamine receptor D1-5 (DRD1-5), adrenoceptor alpha 2A (ADRA2A), catechol-O-methyl-transferase (COMT).
