Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Aripiprazole is a partial agonist at D2 and 5-HT1A receptors and an antagonist at 5-HT2A receptors, stabilizing dopamine and serotonin activity.
Praziquantel increases the permeability of cell membranes to calcium ions in susceptible schistosomes and other trematodes, causing sustained contraction and paralysis of the worm musculature, leading to detachment from blood vessel walls and eventual death.

400 mg IM once monthly after establishing tolerability with oral aripiprazole.
60 mg/kg/day orally in 3 divided doses (20 mg/kg/dose) for 1 day.
Aripiprazole: 75-146 hours; dehydro-aripiprazole: 94-146 hours. Long half-life allows monthly intramuscular dosing.
Terminal elimination half-life is approximately 0.8-1.5 hours for praziquantel; clinical significance: short half-life necessitates multiple dosing for sustained antiparasitic effect.
Primarily hepatic via CYP2D6 and CYP3A4; active metabolite dehydro-aripiprazole.
Extensively metabolized by the liver, primarily by cytochrome P450 enzymes (CYP3A4), to inactive hydroxylated metabolites.
Renal (approximately 25% unchanged and 55% as metabolites); fecal (approximately 20% as metabolites).
Renal excretion accounts for approximately 80-90% of elimination, primarily as metabolites; biliary/fecal excretion is minor (<10%).
Aripiprazole is >99% bound to serum albumin and alpha-1-acid glycoprotein.
Approximately 80-85% bound to serum albumin.
Aripiprazole: 4.9 L/kg (range 3.7-7.2 L/kg), indicating extensive tissue distribution.
Volume of distribution is approximately 2-3 L/kg, indicating extensive tissue distribution.
IM (Abilify Maintena): 100% relative to oral aripiprazole after 5 monthly doses; oral: 87%.
Oral bioavailability is approximately 80% due to extensive first-pass metabolism; higher with food.
No adjustment for mild/moderate impairment; caution in severe impairment (Cr Cl <30 m L/min).
No dosage adjustment required for any degree of renal impairment.
No adjustment for mild impairment; moderate to severe (Child-Pugh class B or C): reduce dose to 300 mg/month.
No specific Child-Pugh based adjustments; contraindicated in hepatocellular carcinoma or history of hepatic encephalopathy; use caution in severe liver disease.
Not approved for pediatric use.
4 years and older: 60 mg/kg/day in 3 divided doses for 1 day; maximum single dose 2 g.
Use cautiously due to increased sensitivity; consider lower doses and monitor for adverse effects.
No specific adjustments; use standard adult dosing with monitoring for adverse effects.
Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death.
None.
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.
Avoid grapefruit juice during treatment due to increased praziquantel exposure.,May cause transient neurologic symptoms in patients with cerebral schistosomiasis or neurocysticercosis due to inflammatory reaction around dying parasites.,Use with caution in patients with hepatic impairment (Child-Pugh class B or C) as metabolism may be reduced.,May exacerbate cysticercosis if used without corticosteroids in neurocysticercosis.,Potential for cardiac arrhythmias in patients with ventricular arrhythmias or electrolyte disturbances (rare).
Hypersensitivity to aripiprazole or any excipients in the formulation.
Hypersensitivity to praziquantel or any component of the formulation,Ocular cysticercosis (due to risk of irreversible ocular damage from inflammatory response),Concurrent use with rifampin (significantly reduces praziquantel plasma concentrations),Children under 1 year of age (safety not established)
No specific food interactions. Grapefruit/grapefruit juice may increase aripiprazole levels (CYP3A4 inhibition). Avoid excessive alcohol consumption.
Take with food to enhance bioavailability. Avoid grapefruit juice as it may increase drug levels. Alcohol may worsen CNS side effects and is not recommended.
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.
Praziquantel (Biltricide) is FDA Pregnancy Category B. Animal studies show no teratogenic effects but embryotoxicity at high doses. Human data limited; no increased risk of major malformations reported. Avoid in first trimester unless essential; use in second/third trimester if benefit outweighs risk.
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.
Praziquantel is excreted into breast milk in small amounts; M/P ratio not established. After a single dose, milk levels low; consider pumping and discarding milk for 24-48 hours post-dose. Use with caution in nursing mothers.
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.
No dose adjustment required for pregnancy; standard dosing (20 mg/kg three times daily for 1 day) unless hepatic impairment present. Pharmacokinetics in pregnancy not significantly altered; unchanged recommendations.
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.
Administer with food to increase absorption and reduce GI side effects. Use with caution in hepatic impairment; dose adjustment may be necessary. Monitor for neuropsychiatric effects (e.g., dizziness, headache) especially in patients with CNS involvement of schistosomiasis. Avoid in patients with ocular cysticercosis due to risk of intraocular inflammation; treat ocular lesions first with corticosteroids.
