Метаболизм

Protriptyline is a dibenzocycloheptriene TCA that differs from the other tricyclics by having an unsaturated ethylene bridge joining the two aromatic rings and a secondary aminopropyl side chain. Protriptyline is completely absorbed from the GI tract and slowly eliminated. Metabolism data are limited for protriptyline, but it is most likely to be metabolized via the same pathways as the other TCAs are. Very little drug is excreted in the feces via the bile.
