AMOXAPINE vs ELAVIL
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.
Amitriptyline inhibits the reuptake of serotonin and norepinephrine in the central nervous system, increasing their synaptic concentrations. It also exhibits anticholinergic, antihistaminergic, and alpha-adrenergic blocking effects.
200-300 mg/day orally in divided doses, initially 50 mg three times daily; maximum 400 mg/day
Oral: Initial 75 mg/day in divided doses or 50-100 mg at bedtime; increase to 150 mg/day; maximum 300 mg/day. IM: 20-30 mg q6h, switch to oral as soon as possible.

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
10–50 hours (mean ~20 hours); terminal elimination half-life is prolonged in elderly and patients with hepatic impairment; steady-state achieved in 7–21 days.
Primarily renal (approximately 60-70% as metabolites, <5% unchanged); minimal fecal elimination (<10%)
Renal (approximately 40% as metabolites, <5% unchanged); biliary/fecal (approximately 60% as metabolites, including glucuronide conjugates).
