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, stabilizing dopamine and serotonin activity.
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
Treatment of schizophrenia,Maintenance monotherapy for bipolar I disorder,Adjunctive treatment of major depressive disorder (off-label),Irritability associated with autistic disorder (off-label),Tourette's disorder (off-label)
400 mg orally once daily for 3 days, then 200 mg once daily for maintenance (up to 12 months).
400 mg IM once monthly after establishing tolerability with oral aripiprazole.
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.
Aripiprazole: 75-146 hours; dehydro-aripiprazole: 94-146 hours. Long half-life allows monthly intramuscular 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.
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% as metabolites).
~99.5% bound to human serum albumin (HSA); binding is high and saturable, with unbound fraction slightly increasing at high concentrations.
Aripiprazole is >99% bound to serum albumin and alpha-1-acid glycoprotein.
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).
Aripiprazole: 4.9 L/kg (range 3.7-7.2 L/kg), indicating extensive tissue 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).
IM (Abilify Maintena): 100% relative to oral aripiprazole after 5 monthly doses; oral: 87%.
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 adjustment for mild/moderate impairment; caution in severe impairment (Cr Cl <30 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 adjustment for mild impairment; moderate to severe (Child-Pugh class B or C): reduce dose to 300 mg/month.
Safety and efficacy not established in pediatric patients (<18 years).
Not approved for pediatric use.
No specific dose adjustment; use with monitoring for renal function due to age-related decline and potential for increased adverse effects.
Use cautiously due to increased sensitivity; consider lower doses and monitor for adverse effects.
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.
Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death.
Hemolytic anemia in G6PD-deficient patients (contraindicated in G6PD deficiency without prior testing),Methemoglobinemia (rare, monitor for cyanosis and dyspnea),Psychiatric effects including anxiety, depression, and insomnia,Hepatotoxicity (rare, monitor liver function),Use in pregnancy: not recommended (risk of hemolysis in G6PD-deficient fetus),Lactation: avoid if breastfeeding infant is G6PD deficient
Increased mortality in elderly dementia patients; suicidal thoughts and behaviors; neuroleptic malignant syndrome; tardive dyskinesia; metabolic changes (hyperglycemia, dyslipidemia, weight gain); orthostatic hypotension; leukopenia/neutropenia; seizure risk; dysphagia; body temperature dysregulation; pathological gambling and other impulse control disorders.
G6PD deficiency (without confirmed normal G6PD activity),Known hypersensitivity to tafenoquine or any 8-aminoquinoline,Use in children <16 years (safety not established),Severe renal impairment (e GFR <30 m L/min),Lactation in infants with G6PD deficiency or unknown G6PD status
Hypersensitivity to aripiprazole or any excipients in the formulation.
Take with a fatty meal to increase absorption. No specific dietary restrictions. Avoid grapefruit juice as it may alter metabolism.
No specific food interactions. Grapefruit/grapefruit juice may increase aripiprazole levels (CYP3A4 inhibition). Avoid excessive alcohol consumption.
FDA Pregnancy Category C. First trimester: animal studies show fetal harm; human data insufficient. Second/third trimester: risk of fetal growth restriction; consider risk-benefit.
First trimester: Limited data, but aripiprazole is not a major human teratogen based on available studies. Second and third trimesters: Neonates exposed to antipsychotics, including aripiprazole, during the third trimester are at risk for extrapyramidal and/or withdrawal symptoms post-delivery.
Excreted in human milk; M/P ratio unknown. Potential for adverse effects in infant; use caution, consider discontinuing breastfeeding.
Aripiprazole is excreted in human breast milk; the estimated infant dose is 0.7–1.4% of maternal weight-adjusted dose. M/P ratio: approximately 0.3–0.5. Limited data suggest no adverse effects in breastfed infants, but long-term safety is unknown.
No established dose adjustments; pharmacokinetic changes in pregnancy may require monitoring drug levels and clinical response.
No specific dose adjustment recommended based on pharmacokinetic changes; however, therapeutic drug monitoring may be considered due to altered metabolism in pregnancy. The long-acting injectable formulation (Abilify Maintena) requires careful timing of doses postpartum to avoid relapse.
ARAKODA (tafenoquine) is indicated for radical cure of Plasmodium vivax malaria. Assess G6PD status before prescribing; contraindicated in G6PD-deficient patients due to hemolytic anemia risk. Monitor for methemoglobinemia. Avoid use in pregnancy/lactation. Take with food to enhance absorption.
Administer every 4 weeks by intramuscular injection only. Do not substitute for oral aripiprazole on a mg-per-mg basis due to different pharmacokinetics. Requires initiation and continuation with oral aripiprazole for 14 days to establish tolerability. Monitor for neuroleptic malignant syndrome, tardive dyskinesia, and metabolic changes. Dose adjustments needed in patients with known CYP2D6 poor metabolizer status or concurrent use of strong CYP2D6 or CYP3A4 inhibitors.
