Second, imipramine is converted in the body to the secondary amine TCA (SATCA), desipramine.188 In the usual patient on imipramine, 50% of the total circulating TCA level will be desipramine. That percentage can be as high as 90% in rapid demethylators. This conversion is an advantage because desipramine has the best tolerability profile of all of the SATCAs due to its selective action on the norepinephrine uptake pump (Figure 6.1). The tolerability profile of desipramine is generally comparable to most newer antidepressants"
