AVENTYL vs DESIPRAMINE HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nortriptyline, the active ingredient, inhibits the reuptake of norepinephrine and serotonin in the central nervous system, potentiating their effects. It also has anticholinergic and antihistaminergic properties.
Inhibits reuptake of norepinephrine and serotonin at presynaptic neuronal membrane, increasing their concentrations in the synaptic cleft.
Adults: 25 mg orally 3 to 4 times daily, maximum 150 mg/day.
Oral: Initial 25-75 mg/day in divided doses; increase gradually to 100-200 mg/day, maximum 300 mg/day. Usual maintenance: 100-200 mg/day single or divided doses.

Terminal elimination half-life: 19-24 hours; requires 4-6 days to reach steady state.
Terminal half-life 12–30 hours (mean ~22 hours); extensive interindividual variability due to CYP2D6 polymorphism.
Renal (30% as unchanged drug and metabolites); biliary/fecal (70% as metabolites)
Renal excretion of metabolites accounts for approximately 70%; fecal elimination ~30%. Unchanged drug <5% in urine.
