AMOXAPINE vs PAMELOR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective inhibitor of serotonin reuptake and, to a lesser extent, norepinephrine reuptake. Also exhibits weak dopamine D2 receptor antagonism and alpha1-adrenergic blockade.
Nortriptyline, the active ingredient, is a tricyclic antidepressant that inhibits the reuptake of norepinephrine and serotonin at the presynaptic neuronal membrane, increasing their availability in the synaptic cleft.
200-300 mg/day orally in divided doses, initially 50 mg three times daily; maximum 400 mg/day
25-150 mg orally per day, typically as a single daily dose at bedtime or in divided doses; start at 25 mg 1-3 times daily and titrate gradually. Maximum 150 mg/day.

Clinical Note
moderateAmoxapine + Budesonide
"The therapeutic efficacy of Budesonide can be decreased when used in combination with Amoxapine."
Clinical Note
moderateAmoxapine + Fluticasone furoate
"The therapeutic efficacy of Fluticasone furoate can be decreased when used in combination with Amoxapine."
Clinical Note
moderateAmoxapine + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Amoxapine is combined with Fluticasone propionate."
Clinical Note
moderateParent drug: 8-12 hours; active metabolite (8-hydroxyamoxapine): approximately 30 hours; steady-state achieved in 3-5 days
Mean terminal elimination half-life is 18-24 hours (range 13-40 hours) in adults; prolonged in elderly and hepatic impairment (up to 60 hours). Steady-state achieved in 4-5 days.
Primarily renal (approximately 60-70% as metabolites, <5% unchanged); minimal fecal elimination (<10%)
Primarily renal (approximately 70% as metabolites, 40-50% as glucuronide conjugates, 20-30% as free or conjugated nortriptyline; <5% unchanged), with 20-30% biliary/fecal elimination.
