Aripiprazole: 75 hours; dehydro-aripiprazole: 94 hours. Steady-state reached in ~14 days.
Terminal elimination half-life is approximately 3-4 hours in patients with normal renal function; may be prolonged in renal impairment.
Hepatic metabolism primarily via CYP3A4 and CYP2D6; also by dehydrogenation and N-dealkylation.
Partially metabolized in the liver; some metabolites are excreted unchanged.
Renal (25% unchanged, 18% as dehydro-aripiprazole) and fecal (55% unchanged and metabolites).
Renal elimination of unchanged drug and metabolites accounts for approximately 70-80%, with the remainder excreted in feces via biliary elimination.
>99% bound to albumin and alpha-1-acid glycoprotein.
Approximately 90% bound to plasma proteins, primarily albumin.
4.9 L/kg (high distribution into tissues).
Volume of distribution is approximately 0.6-1.0 L/kg, indicating distribution into total body water.
Oral: 87% (tablet and solution); IM: 100%.
Oral bioavailability is approximately 80-90% due to extensive absorption with minimal first-pass metabolism.
No dosage adjustment required for renal impairment; not removed by hemodialysis.
GFR 10-50 m L/min: administer 50-75% of normal dose; GFR <10 m L/min: administer 25-50% of normal dose; hemodialysis: administer after dialysis.
No specific guidelines; use caution in severe hepatic impairment (Child-Pugh class C) due to limited data.
Child-Pugh Class A: no adjustment; Class B: reduce dose by 25-50%; Class C: contraindicated or use with extreme caution, reduce dose by 75%.
Schizophrenia (13-17 years): 2 mg/day, target 10-25 mg/day. Bipolar mania (10-17 years): 2 mg/day, target 10-30 mg/day. Autism irritability (6-17 years): 2 mg/day, target 5-15 mg/day.
Children: 10-20 mg/kg/day orally in 2 divided doses; maximum 750 mg/day for <10 kg, 1.5 g/day for 10-20 kg, 2.25 g/day for 20-40 kg, 3 g/day for >40 kg.
Initiate at lower doses (e.g., 2-5 mg/day) and titrate slowly due to increased risk of adverse effects, especially orthostatic hypotension and cognitive decline.
Elderly: initiate at lower end of dosing range; monitor renal function and adjust dose accordingly; avoid in patients with significant hepatic impairment.
Increased risk of death in elderly patients with dementia-related psychosis due to cerebrovascular events.
None.
Increased mortality in elderly dementia patients, suicidal thoughts/behaviors, neuroleptic malignant syndrome, tardive dyskinesia, metabolic changes (hyperglycemia, dyslipidemia, weight gain), orthostatic hypotension, leukopenia/neutropenia, seizures, body temperature dysregulation, dysphagia, impulse control disorders.
Caution in patients with epilepsy or impaired renal function; may cause neurotoxicity at high doses.
Known hypersensitivity to aripiprazole or any of its excipients.
Hypersensitivity to piperazine; patients with pre-existing neurological disorders such as epilepsy.
Grapefruit juice may increase aripiprazole exposure; avoid concurrent intake. No other significant food interactions. Alcohol can enhance CNS depression; limit or avoid.
No significant food interactions reported. Avoid alcohol as it may increase CNS side effects. Take with food if gastrointestinal upset occurs.
Pregnancy category C. First trimester: risk of major malformations not significantly increased based on limited data; however, neurodevelopmental effects uncertain. Second and third trimesters: neonates exposed in late pregnancy are at risk for extrapyramidal symptoms (EPS) and withdrawal syndrome including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, feeding disorder.
ANTEPAR (piperazine citrate) is classified as FDA Pregnancy Category C. Animal studies have shown embryotoxic effects at high doses, but no well-controlled human studies exist. First trimester exposure may be associated with a slightly increased risk of congenital anomalies, though data are limited. Second and third trimester risks are not well-defined; use only if clearly needed.
Aripiprazole is excreted in human breast milk; milk-to-plasma (M/P) ratio is approximately 0.5 to 1.0. Relative infant dose is estimated to be 1-3% of maternal weight-adjusted dose. Limited data; use with caution. Monitor infant for sedation, poor feeding, and abnormal movements.
Piperazine is excreted into breast milk in small amounts. The M/P ratio is not established. The American Academy of Pediatrics considers piperazine compatible with breastfeeding, but caution is advised due to potential adverse effects in nursing infants. Use only if benefits outweigh risks.
No established pharmacokinetic data; however, pregnancy-induced physiological changes (increased plasma volume, renal clearance) may lower aripiprazole levels. Monitor therapeutic efficacy and consider dose adjustment if symptom exacerbation. No specific dose modification guidelines available; titrate based on clinical response and tolerability.
No specific dose adjustments recommended during pregnancy. Piperazine pharmacokinetics may be altered due to increased plasma volume and renal clearance, but standard dosing is generally used. Monitor for efficacy and adverse effects.
Abilify (aripiprazole) is a partial dopamine agonist, which reduces the risk of extrapyramidal symptoms and hyperprolactinemia compared to full antagonists. Monitor for akathisia, especially during dose titration. QT prolongation risk is lower than with other antipsychotics; use caution in patients with cardiac disease. Avoid use in dementia-related psychosis due to increased mortality. Therapeutic effects may take 2-4 weeks; full response often requires 6-8 weeks.
ANTEPAR (piperazine) is a first-line treatment for ascariasis and enterobiasis. It causes neuromuscular paralysis in worms via GABA receptor agonism. Contraindicated in epilepsy and renal impairment. Monitor for neurotoxicity (ataxia, confusion) especially in children. Effective against both adult and immature worms; no need for laxatives.

Common clinical questions about ABILIFY vs ANTEPAR, answered by our medical review team.
ABILIFY is a Atypical antipsychotic that works by Partial agonist at dopamine D2 and serotonin 5-HT1A receptors; antagonist at serotonin 5-HT2A receptors.. ANTEPAR is a Anthelmintic that works by Piperazine, the active ingredient, causes paralysis of the parasite by blocking acetylcholine at the neuromuscular junction and altering muscle membrane ion permeability.. They differ in pharmacokinetic profiles, FDA-approved indications, and side effect profiles.
Potency comparisons between ABILIFY and ANTEPAR depend on the specific clinical indication. These are agents from distinct pharmacological classes and are not directly interchangeable by dose. A physician or clinical pharmacist should guide any therapeutic switching decisions.

Adjunctive MDD: 2-5 mg once daily, titrating to 5-10 mg. Autism irritability: 2 mg/day initially, titrated to 5-10 mg/day (max 15 mg/day).. The standard adult dose of ANTEPAR is: Adult: 50-75 mg/kg/day orally in 3 divided doses for 3 days; maximum 3 g/day.. Dosing should always be individualized based on indication, renal and hepatic function, age, and other patient factors.
No direct drug-drug interaction has been formally documented between ABILIFY and ANTEPAR in current clinical databases. However, individual patient risk factors including other medications, organ function, and comorbidities should always be evaluated by a qualified healthcare provider.
The maternal-fetal safety profiles differ. ABILIFY is classified as Category C. Pregnancy category C. First trimester: risk of major malformations not significantly increased based on limited data; however, neurodevelopmental effects uncertain. Second and thir. ANTEPAR is classified as Category C. ANTEPAR (piperazine citrate) is classified as FDA Pregnancy Category C. Animal studies have shown embryotoxic effects at high doses, but no well-controlled human studies exist. Fir.
