Infobord.png More information
  • Paroxetine slows the metabolism of nortriptyline via CYP2D6.
  • Due to CYP inhibition a longer period of time is needed to reach steady state concentration. Please keep in mind when monitoring plasma levels
  • Plasma monitoring for TCA's is advisable, because of plasma-reponse relations, genetic polymorphism and under or overdosing.[3]
