Hi, Patientswho are poor metabolizers (individuals with no CYP2D6 activity) or ultrarapid metabolizers (individuals with genetically elevated CYP2D6 activity) can have markedly altered response to drugs that are CYP2D6 substrates. Analysis from pooled data suggests that CYP2D6 poor metabolizers have greater increases in heart rate, diastolic blood pressure and frequency of tremors, as compared to CYP2D6 normal metabolizers. Atomoxetine's primary mode of oxidative metabolism is through the enzyme CYP2D6 resulting in the formation of 4-hydroxyatomoxetine, which has equipotent inhibition of the reuptake of norepinephrine in the synaptic cleft (this will be important later on in the consideration of potential side effects).1,4,5 I would love to be able to test my Ninja Boy!
