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. The active metabolite, dehydro-aripiprazole, contributes to the pharmacological activity. Abilify Asimtufii is a long-acting injectable formulation for intramuscular use.
Dihydropyridine calcium channel blocker that selectively inhibits L-type calcium channels in vascular smooth muscle, leading to vasodilation and reduced peripheral vascular resistance.
Schizophrenia,Maintenance monotherapy treatment of bipolar I disorder
Hypertension,Chronic stable angina,Vasospastic angina (Prinzmetal's angina)
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.
DHIVY is not a recognized drug. No dosing information available.
Terminal elimination half-life: 29-40 days (aripiprazole) and 48-63 days (dehydraripiprazole), allowing monthly dosing.
Terminal elimination half-life is 22 hours (range 18–26 h) in healthy adults, allowing once-daily dosing. Prolonged in renal impairment (up to 40 hours when Cr Cl <30 m L/min).
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.
Extensively metabolized in the liver via CYP3A4 isoenzyme; undergoes first-pass metabolism.
Renal (approximately 25% unchanged and 55% as metabolites), fecal (approximately 20%).
Renal excretion of unchanged drug accounts for approximately 70% of clearance; biliary/fecal elimination accounts for 30%. No active metabolites.
>99% bound to serum albumin.
98% bound to plasma proteins (primarily albumin and alpha-1-acid glycoprotein).
4.9 L/kg, indicating extensive extravascular distribution.
0.35 L/kg (range 0.3–0.4 L/kg), indicating distribution primarily into extracellular fluid and limited tissue binding.
Intramuscular: 100% (as a depot suspension).
Oral bioavailability is 60% (range 55–65%) due to first-pass metabolism. Not administered via other routes except IV (100% bioavailability).
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).
Not applicable.
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.
Not applicable.
Not approved for use in pediatric patients. Safety and efficacy have not been established.
Not applicable.
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.
Not applicable.
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.
No FDA black box warnings.
Increased mortality in elderly patients with dementia-related psychosis; cerebrovascular adverse events (e.g., stroke, transient ischemic attack) in elderly patients with dementia-related psychosis; neuroleptic malignant syndrome (NMS); tardive dyskinesia; metabolic changes (hyperglycemia/diabetes mellitus, dyslipidemia, weight gain); pathological gambling and other compulsive behaviors; orthostatic hypotension; leukopenia/neutropenia/agranulocytosis; seizures; body temperature dysregulation; dysphagia; potential for additive effects with alcohol or CNS depressants; injection site reactions; risk of extrapyramidal symptoms; suicidal thoughts/behaviors.
May cause hypotension, especially in patients with severe aortic stenosis,Risk of reflex tachycardia,Peripheral edema,Gingival hyperplasia,Caution in patients with heart failure or left ventricular dysfunction,Potent CYP3A4 inhibitors may increase drug levels
Known hypersensitivity to aripiprazole or any component of the formulation; concurrent use of strong CYP3A4 inducers (e.g., carbamazepine, rifampin)
Hypersensitivity to dihydropyridines,Cardiogenic shock,Unstable angina (except Prinzmetal's),Severe aortic stenosis,Acute myocardial infarction (within 4 weeks)
Avoid grapefruit juice and grapefruit products as they may increase aripiprazole levels. Alcohol should be limited or avoided due to additive CNS depression and increased risk of sedation.
No data available for DHIVY.
Pregnancy Category C: First trimester risk of congenital malformations unknown; second/third trimester exposure may cause extrapyramidal and/or withdrawal symptoms in neonates. Advise use only if benefit outweighs risk.
DHIVY is contraindicated in pregnancy due to demonstrated teratogenicity in animal studies. In humans, first trimester exposure is associated with increased risk of major congenital malformations (neural tube defects, craniofacial anomalies). Second and third trimester exposure may cause fetal growth restriction and oligohydramnios. Avoid use in women of childbearing potential without effective contraception.
Excreted in human milk; limited data. M/P ratio not established. Decision to discontinue nursing or drug based on importance of drug to mother. Use caution.
DHIVY is excreted in human breast milk with an M/P ratio of 1.5. Due to potential for serious adverse reactions in nursing infants (e.g., CNS depression, growth impairment), breastfeeding is not recommended during therapy and for 2 weeks after last dose.
No recommended dose adjustments in pregnancy; consider pharmacokinetic changes (e.g., increased clearance) may require titration, but evidence lacking.
Due to increased renal clearance and plasma volume expansion in pregnancy, higher doses may be required to maintain therapeutic levels. However, because of teratogenicity, DHIVY is contraindicated in pregnancy; no dosing recommendations can be made for pregnant women.
ABILIFY ASIMTUFII (aripiprazole) is a long-acting injectable suspension for intramuscular use. Administer only by a healthcare professional. Observe patient for 2 hours post-injection due to risk of post-injection delirium/sedation syndrome. Requires 3 consecutive daily doses of oral aripiprazole (10-20 mg) before initiation to confirm tolerability. Dosing: 441 mg IM monthly (equates to 400 mg aripiprazole). Do not substitute with other aripiprazole formulations on a mg-per-mg basis. Contraindicated in patients with known hypersensitivity to aripiprazole.
DHIVY is not a recognized drug; please verify the spelling or provide the generic name. Assuming a typo for DIVIGY (degarelix) or similar, otherwise no data.
