It undergoes a process of metabolic biotransformación by the CYP2D6 and is for that reason that its association with inhibitors of this isoenzima like paroxetina, and quinidona they would increase the séricos levels of atomoxetina forcing to an adjustment posológico. The main formed metabolito is the 4-hidroxiatomoxetina O-glucurónico that is of smaller activity than the drug mother and is eliminated in his greater proportion by tinkles (80%) and the rest by lees.

The correlation has not been established of conclusive way and still he is preliminary.
The simultaneous administration of the atomoxetina with drugs that act on isoenzima CYP2D6 inhibiting it (paroxetina, and quinidina) can increase the concentrations plasmáticas of the same one. The concomitante use with the broncodilatador salbutamol can increase to the cardiotónicos and vasopresores effects of the stimulation adrenérgica beta-2.
