> > > But I've been meaning to ask you, to ask you all, actually...do you know of any interactions between smoking and Nardil or Nortryp? I mean like kinetic and metabolic interactions that could lower blood concentrations, that sort of things. I've checked my references and they've mentioned nothing, but I thought I'd pass it by you too.

Tricyclics are metabolized by cytochrome enzymes. The main metabolic pathway for Nardil metabolism is actually oxidation via MAO. Nardil inhibits its own metabolism. Nardil is also metabolized via acetylation, albeit to a lesser extent.

Oh. Sorry...I have never encountered any research nor has any doctor ever mentioned to me any kind of interactions between smoking and these two drugs. I think you would be in a better position than me to research it. I am not familiar with how smoking affects the levels of different drugs. If smoking is an inhibitor or inducer of CYP2D6, nortriptyline levels would be affected. CYP1A2 is only a minor metabolic pathway.
