De to hovedmetabolitter er pyridin- 3- carbonisk syremetabolit og en 2- hydroxymethyl- pyridin - 3- carbonisk syremetabolit eller, afhængigt af pH- værdien, dens lactonform.
The two main metabolites are the pyridine-3-carbonic acid metabolite and a 2-hydroxymethyl- pyridine-3-carbonic acid metabolite or, depending on the pH, its lacton form.
