effect Doxepin affects the central nervous system as an inhibitor of monoamine reuptake from the synaptic cleft into presynaptic vesicles, also anticholinergic, antihistaminic and adrenolytisch (the action of adrenaline picking). The increased through the (unselective) reuptake inhibition availability of serotonin and norepinephrine in neuronal transmission results in alleviation of depressive symptoms. The effects of several transmitter systems by doxepin produced its characteristic side effects, which largely correspond to those of other tricyclic antidepressants. The sedative effect decreases often during prolonged ingestion. The desired sentiment occurs only after a treatment period of two to three weeks.
