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.
AMVAZ (amivantamab-vmjw) is a bispecific monoclonal antibody that targets the extracellular domains of epidermal growth factor receptor (EGFR) and mesenchymal-epithelial transition factor (MET). It inhibits ligand binding, receptor activation, and downstream signaling, leading to antibody-dependent cellular cytotoxicity and tumor cell death.

FDA-approved for the treatment of adult patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 20 insertion mutations, as detected by an FDA-approved test, whose disease has progressed on or after platinum-based chemotherapy.
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: 500 mg every 6 hours.
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 12-18 hours; prolonged in renal impairment (up to 30 hours) requiring dose adjustment.
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.
AMVAZ is a monoclonal antibody; it is degraded into small peptides and amino acids via general protein catabolism. No specific metabolic pathways or enzymes involved.
Aripiprazole: ~25% renal, ~55% fecal; unchanged drug accounts for <1% renal. Dehydro-aripiprazole (active metabolite): excreted similarly.
Primarily renal excretion of unchanged drug (60-70%) and metabolites (10-20%); biliary/fecal excretion accounts for 15-25%.
Aripiprazole: >99% bound to albumin and alpha-1-acid glycoprotein. Dehydro-aripiprazole: >99% bound.
98% bound to albumin primarily, with minor binding to alpha-1-acid glycoprotein.
Aripiprazole: 4.9 L/kg (IV). High Vd indicates extensive tissue distribution.
0.2-0.3 L/kg, indicating minimal extravascular distribution and confinement to plasma volume.
Oral: 87% (absolute). Tablet and orally disintegrating tablet are bioequivalent.
Oral bioavailability is 85-95%; reduced to 60-70% when taken with high-fat meals.
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.
Cr Cl 30-50 m L/min: 250 mg every 6 hours; Cr Cl 15-29 m L/min: 250 mg every 12 hours; Cr Cl <15 m L/min: 250 mg every 24 hours; hemodialysis: 250 mg after dialysis.
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.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 25%; Child-Pugh C: reduce dose by 50%.
Not approved for patients <18 years; safety and effectiveness not established.
10 mg/kg IV every 6 hours; maximum 500 mg per dose.
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.
Consider renal function; start at lower end of dosing range due to age-related decreased renal clearance.
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 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.
Avoid grapefruit and grapefruit juice as they inhibit CYP3A4 metabolism, increasing amiodarone levels and risk of toxicity. Limit alcohol consumption due to potential hepatotoxicity. High-fat meals may increase absorption; take consistently with or without food.
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).
No human data available; in animal studies, no teratogenicity observed at clinically relevant doses. First trimester: data insufficient to assess risk. Second and third trimesters: no known fetal harm.
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 excretion in human milk; M/P ratio unknown. Caution recommended; benefits of breastfeeding should be weighed against potential risk to infant.
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 specific dose adjustments required in pregnancy; pharmacokinetic changes not well-characterized. Use lowest effective dose and monitor clinical response.
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.
AMVAZ (amiodarone) has a long half-life (up to 107 days) and can cause thyroid, pulmonary, hepatic, and skin toxicity. Monitor thyroid function (TSH, T3, T4), liver enzymes (ALT, AST), and perform baseline pulmonary function tests and chest X-ray. Corneal microdeposits are common and may cause visual halos; usually reversible. Administer loading dose to achieve therapeutic effect more quickly. Avoid use with grapefruit juice as it increases drug levels.
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.
Take AMVAZ exactly as prescribed; do not stop without consulting your doctor.,Avoid grapefruit and grapefruit juice while taking this medication.,Report any new or worsening shortness of breath, cough, chest pain, or palpitations immediately.,Notify your doctor if you experience vision changes, yellowing of skin/eyes, dark urine, or unusual fatigue.,Use effective contraception during treatment and for at least 6 months after stopping.,Avoid excessive sun exposure; use sunscreen and protective clothing due to risk of skin discoloration and photosensitivity.,Do not take over-the-counter medications or herbal supplements without checking with your doctor.,Regular blood tests and eye exams are necessary while on this medication.
