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 D3 dopamine receptors and 5-HT1A serotonin receptors, and an antagonist at 5-HT2A serotonin receptors. It also exhibits moderate affinity for histamine H1 receptors and alpha1-adrenergic receptors. The My Cite kit includes a sensor that detects tablet ingestion and transmits data to a wearable patch.
Angiotensin II acetate is a synthetic peptide that acts as a potent vasoconstrictor by binding to the angiotensin II type 1 (AT1) receptor on vascular smooth muscle cells, leading to increased intracellular calcium and smooth muscle contraction. It also stimulates aldosterone secretion from the adrenal cortex, promoting sodium and water retention.

Treatment of hypotension in adults with septic or other distributive shock (FDA approved)
Oral: 10-15 mg once daily; dose range 5-30 mg/day; titrate based on response and tolerability. The MYCITE sensor is applied to the tablet; the patch and app are for adherence monitoring only.
Intravenous infusion: 1-40 ng/kg/min titrated to achieve target blood pressure. Initial rate: 10 ng/kg/min.
Aripiprazole: 75 hours (range 48–146 h). Dehydro-aripiprazole: 94 hours (range 48–206 h). Steady state reached in 14 days.
Terminal elimination half-life is approximately 30-60 minutes; clinical effect is short-lived requiring continuous intravenous infusion.
Aripiprazole is metabolized primarily by CYP2D6 and CYP3A4. The major active metabolite is dehydro-aripiprazole (formed by CYP2D6). Phase I reactions include dehydrogenation and hydroxylation. Phase II glucuronidation of hydroxylated metabolites occurs.
Primarily metabolized by aminopeptidases and other peptidases in plasma and tissues, with minimal hepatic involvement.
Aripiprazole: ~25% renal, ~55% fecal; unchanged drug accounts for <1% renal. Dehydro-aripiprazole (active metabolite): excreted similarly.
Primarily renal (90-100%) as unchanged drug; minimal biliary/fecal elimination (<10%).
Aripiprazole: >99% bound to albumin and alpha-1-acid glycoprotein. Dehydro-aripiprazole: >99% bound.
Approximately 30% bound to plasma proteins, primarily albumin.
Aripiprazole: 4.9 L/kg (IV). High Vd indicates extensive tissue distribution.
Approximately 0.3-0.5 L/kg; indicates distribution mainly in extracellular fluid.
Oral: 87% (absolute). Tablet and orally disintegrating tablet are bioequivalent.
Intravenous: 100%; subcutaneous/intramuscular: not well absorbed due to rapid local metabolism; oral: negligible (<1%) due to extensive first-pass metabolism.
No dose adjustment required for mild to moderate renal impairment (Cr Cl ≥15 m L/min). Not recommended for severe renal impairment (Cr Cl <15 m L/min) due to lack of data.
No specific dose adjustment required for renal impairment. Use caution in patients with renal artery stenosis.
Child-Pugh Class A or B: No dose adjustment necessary. Child-Pugh Class C: Use with caution; maximum dose 10 mg/day due to increased exposure.
No specific dose adjustment required for hepatic impairment.
Not approved for patients <18 years; safety and effectiveness not established.
Intravenous infusion: 0.5-20 ng/kg/min titrated to effect. Safety and efficacy not established in neonates.
No specific dose adjustment; use lower starting doses (e.g., 5 mg/day) due to increased sensitivity and risk of adverse effects, especially orthostatic hypotension and tardive dyskinesia.
Start at lower end of dosing range (1-5 ng/kg/min) due to potential for decreased renal function and increased sensitivity.
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. Aripiprazole is not approved for the treatment of patients with dementia-related psychosis.
No boxed warnings.

Thrombotic and thromboembolic events: Increased risk of venous and arterial thromboembolic events, including deep vein thrombosis, pulmonary embolism, and myocardial infarction.,Ischemic events: May cause cardiac ischemia and reduce cardiac output; use with caution in patients with coronary artery disease.,Vascular thrombosis: High risk of vascular thrombosis in patients with a history of thrombosis or hypercoagulable states.,Use in hypovolemia: Correct hypovolemia before administration to avoid exacerbation of vasoconstriction.,Pregnancy: May cause fetal harm; avoid use in pregnant women unless potential benefit outweighs risk.
Hypersensitivity to aripiprazole or any component of the formulation,Concurrent use with ziprasidone (QT prolongation risk)
Hypersensitivity to angiotensin II acetate or any component of the formulation,No absolute contraindications listed by the manufacturer; however, use is avoided in patients with uncorrected hypovolemia and those with a history of thromboembolic events.
No specific food interactions are reported for the sensor component. Aripiprazole can be taken with or without food. However, avoid excessive alcohol consumption as it may increase central nervous system depression or worsen side effects. Grapefruit and grapefruit juice do not significantly interact with aripiprazole metabolism (CYP3A4 minor pathway); no restriction needed.
No food interactions specific to angiotensin II acetate. Maintain a balanced diet as tolerated. Avoid excessive salt intake unless directed otherwise, as it may counteract the medication's effect on blood pressure.
First trimester: Limited human data; animal studies show developmental toxicity (reduced fetal weight, delayed ossification) at doses similar to human exposure. Second/third trimester: Neonates exposed to antipsychotics (including aripiprazole) during late pregnancy may experience extrapyramidal symptoms and/or withdrawal symptoms (agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, feeding disorder).
First trimester: Potential for teratogenicity (increased risk of cardiovascular and CNS malformations). Second and third trimesters: Fetal hypotension, anuria, oligohydramnios, skull hypoplasia, pulmonary hypoplasia, and death. Use contraindicated in pregnancy.
Aripiprazole is present in human breast milk; limited data suggest infant serum levels are low but can vary. M/P ratio not established. Caution advised; monitor infant for sedation, irritability, and feeding problems.
No data on M/P ratio. Likely excreted in breast milk. Avoid breastfeeding due to unknown risks to neonate.
No specific dose adjustment recommended; however, pregnancy may alter aripiprazole pharmacokinetics (decreased exposure due to increased volume of distribution and clearance). Monitor clinical response and consider dose adjustment if efficacy or tolerability changes. Use lowest effective dose.
No dose adjustment recommended if used; however, if inadvertently exposed, discontinue drug. Pharmacokinetic changes in pregnancy (increased volume of distribution, enhanced clearance) may lower drug levels, but no established dose adjustment.
Abilify My Cite is aripiprazole tablets embedded with an ingestible sensor (Ingestible Event Marker, IEM) that communicates with a wearable patch to record medication ingestion. It is used for schizophrenia, bipolar I disorder, and as adjunctive therapy for major depressive disorder. The sensor does not monitor drug levels or efficacy; it only confirms ingestion. Ensure the patient has a compatible smartphone and the My Cite app. The patch must be replaced weekly. Avoid MRI, CT, or diathermy near the patch; remove if undergoing these procedures. Monitor for aripiprazole side effects: akathisia, metabolic changes, tardive dyskinesia, and neuroleptic malignant syndrome. The ingestible sensor contains copper, magnesium, and silicon; allergy risk is low but possible.
ANGIOTENSIN II ACETATE is a vasoconstrictor used for refractory hypotension in distributive shock. Administer via central line to avoid extravasation, which can cause severe tissue ischemia. Monitor blood pressure every 5 minutes during titration. Discontinue other vasopressors if possible to avoid additive arrhythmogenic effects. Use with caution in patients with coronary artery disease or previous myocardial infarction due to increased oxygen demand. Taper gradually to avoid rebound hypotension.
Take Abilify My Cite by mouth as directed. The sensor in the tablet activates upon contact with stomach fluid. Wear the My Cite patch on your left upper abdomen, replacing it weekly. Use the My Cite app to scan the tablet's QR code and confirm ingestion. Do not crush or chew the tablet. If a dose is missed, take it as soon as remembered unless it is close to the next dose. Do not double doses.,The patch is not MRI compatible; remove it before any MRI, CT scan, or diathermy procedure. Inform all healthcare providers that you use this system. The patch contains no latex. You may feel a mild sensation when the patch communicates with your phone. Keep your phone nearby (within Bluetooth range) for recording.,Common side effects of aripiprazole include nausea, vomiting, constipation, headache, dizziness, insomnia, restlessness, and weight gain. Seek medical attention for severe muscle stiffness, fever, confusion, irregular heartbeat, or suicidal thoughts. Avoid alcohol and activities requiring mental alertness until you know how this medication affects you.,The ingestible sensor is generally safe, but if you have a sensitivity to copper, magnesium, or silicon, discuss with your doctor. The patch may cause skin irritation; if it persists, stop use and contact your provider.,Do not rely solely on the app to confirm ingestion; it is not a substitute for clinical judgment. Store tablets at room temperature, away from moisture and heat. Keep out of reach of children.
