Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
ARAKODA (tafenoquine) is an 8-aminoquinoline antimalarial agent that inhibits the conversion of Plasmodium protozoa from liver stage to blood stage, thereby preventing relapses. Its exact mechanism may involve interference with electron transport or generation of reactive oxygen species.
Aripiprazole is a partial agonist at D2 and 5-HT1A receptors and an antagonist at 5-HT2A receptors. The active metabolite, dehydro-aripiprazole, contributes to the pharmacological activity. Abilify Asimtufii is a long-acting injectable formulation for intramuscular use.
Radical cure (prevention of relapse) of Plasmodium vivax malaria in patients aged 16 years and older who are receiving appropriate antimalarial therapy for acute P. vivax infection
Schizophrenia,Maintenance monotherapy treatment of bipolar I disorder
400 mg orally once daily for 3 days, then 200 mg once daily for maintenance (up to 12 months).
Recommended starting dose: 400 mg intramuscularly once monthly, with a single oral dose of 10-20 mg aripiprazole or continued oral therapy for 14 days to ensure tolerability. Maintenance dose: 300-400 mg monthly.
Terminal elimination half-life: approximately 14-16 days (range 12-19 days) in healthy adults; this long half-life is due to extensive tissue distribution and slow release from tissues, providing prophylactic coverage for up to 4 weeks after a single dose.
Terminal elimination half-life: 29-40 days (aripiprazole) and 48-63 days (dehydraripiprazole), allowing monthly dosing.
Primarily metabolized by CYP2D6 and monoamine oxidase (MAO). Tafenoquine undergoes extensive metabolism including N-dealkylation and oxidation.
Primarily hepatic via CYP2D6 and CYP3A4; active metabolite dehydro-aripiprazole is formed primarily by CYP3A4 and CYP2D6; exhibits significant interindividual variability due to CYP2D6 polymorphism.
Biliary/fecal: ~90% unchanged; renal: <1% unchanged (dose-proportional urinary excretion of tafenoquine is minimal, with most eliminated via feces as unchanged drug and minor metabolites).
Renal (approximately 25% unchanged and 55% as metabolites), fecal (approximately 20%).
~99.5% bound to human serum albumin (HSA); binding is high and saturable, with unbound fraction slightly increasing at high concentrations.
>99% bound to serum albumin.
Apparent Vd: ~2000 L (or ~24-30 L/kg based on 70 kg), indicating extensive tissue distribution (concentrated in red blood cells, liver, lungs, and adipose tissue).
4.9 L/kg, indicating extensive extravascular distribution.
Oral: ~100% (absolute bioavailability not formally determined, but absorption is complete with minimal first-pass metabolism; relative bioavailability is high based on AUC and clinical efficacy).
Intramuscular: 100% (as a depot suspension).
No dose adjustment required for mild to moderate renal impairment (Cr Cl ≥30 m L/min). Not recommended for severe renal impairment (Cr Cl <30 m L/min) due to lack of data.
No dosage adjustment required for patients with renal impairment (Cr Cl ≥15 m L/min). Insufficient data for patients with end-stage renal disease (Cr Cl <15 m L/min).
Contraindicated in Child-Pugh Class B or C. Use with caution in mild hepatic impairment (Child-Pugh Class A) with no dose adjustment.
No dosage adjustment recommended for mild to moderate hepatic impairment (Child-Pugh class A or B). Use with caution in severe hepatic impairment (Child-Pugh class C) as experience is limited.
Safety and efficacy not established in pediatric patients (<18 years).
Not approved for use in pediatric patients. Safety and efficacy have not been established.
No specific dose adjustment; use with monitoring for renal function due to age-related decline and potential for increased adverse effects.
Use with caution due to increased sensitivity to orthostatic hypotension and sedative effects. Consider lower starting doses (300 mg orally equivalent) but no specific dose adjustment for the injectable form is recommended.
ARAKODA can cause hemolytic anemia in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency. G6PD testing must be performed before prescribing due to risk of hemolytic anemia.
WARNING: INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS. Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Abilify Asimtufii is not approved for the treatment of patients with dementia-related psychosis.
