AMITRIL vs AMOXAPINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amitriptyline inhibits the reuptake of serotonin and norepinephrine, thereby increasing their synaptic concentrations. It also blocks histamine H1, alpha-1 adrenergic, and muscarinic receptors.
Selective inhibitor of serotonin reuptake and, to a lesser extent, norepinephrine reuptake. Also exhibits weak dopamine D2 receptor antagonism and alpha1-adrenergic blockade.
Adults: Initial 25 mg PO once daily at bedtime, increase by 25 mg every 3-7 days as tolerated to typical maintenance 75-150 mg/day PO divided doses or single dose at bedtime. Maximum 300 mg/day.
200-300 mg/day orally in divided doses, initially 50 mg three times daily; maximum 400 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
moderateTerminal elimination half-life: 15–25 hours (mean 20 h); may extend to >40 h in elderly or hepatic impairment.
Parent drug: 8-12 hours; active metabolite (8-hydroxyamoxapine): approximately 30 hours; steady-state achieved in 3-5 days
Renal: ~70% as metabolites, <5% unchanged; fecal: ~30% via bile.
Primarily renal (approximately 60-70% as metabolites, <5% unchanged); minimal fecal elimination (<10%)
