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.
SURITAL (thiamylal) is an ultra-short-acting barbiturate that enhances GABA-A receptor activity, increasing chloride ion conductance and neuronal hyperpolarization, resulting in rapid induction of anesthesia.

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.
Induction: 3-5 mg/kg IV bolus over 10-15 seconds. Maintenance: 0.5-1.5 mg/kg IV as needed for anesthesia. Also used as 0.2-0.4% solution for IV infusion at 0.5-2 mg/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 2-8 hours (mean 4.5 h) in adults; prolonged in hepatic impairment.
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 hepatic metabolism via microsomal enzyme oxidation (CYP2B6, CYP3A4) to inactive metabolites; minor renal excretion.
Aripiprazole: ~25% renal, ~55% fecal; unchanged drug accounts for <1% renal. Dehydro-aripiprazole (active metabolite): excreted similarly.
Primarily renal excretion of metabolites; <1% unchanged. Minor biliary/fecal elimination.
Aripiprazole: >99% bound to albumin and alpha-1-acid glycoprotein. Dehydro-aripiprazole: >99% bound.
~70% bound to albumin.
Aripiprazole: 4.9 L/kg (IV). High Vd indicates extensive tissue distribution.
1.5-2.5 L/kg; indicates extensive tissue distribution.
Oral: 87% (absolute). Tablet and orally disintegrating tablet are bioequivalent.
IM: ~90%.
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 GFR-based adjustments; metabolized primarily in liver. Caution in severe renal impairment due to potential accumulation of inactive metabolites.
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 50% and titrate to effect. Child-Pugh C: Contraindicated or use with extreme caution with reduced doses (e.g., 25-50% of normal).
Not approved for patients <18 years; safety and effectiveness not established.
Induction: 3-6 mg/kg IV. Maintenance: 1-2 mg/kg IV as needed. Use with caution; not recommended for 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.
Reduce dose by 30-50% due to decreased clearance and increased sensitivity. Administer slowly and titrate to effect.
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.
WARNING: RESPIRATORY DEPRESSION AND CARDIAC ARREST. SURITAL may cause severe respiratory depression or apnea, especially with rapid administration. Resuscitative equipment and personnel trained in airway management must be immediately available. Avoid intra-arterial injection due to risk of arteriospasm, thrombosis, and gangrene.

Monitor respiratory and cardiac function continuously; use with caution in patients with respiratory compromise, hypotension, shock, or hepatic/renal impairment; may cause laryngospasm, bronchospasm, or hypotension; avoid extravasation; use with caution in porphyria.
Hypersensitivity to aripiprazole or any component of the formulation,Concurrent use with ziprasidone (QT prolongation risk)
Absolute: Known hypersensitivity to barbiturates, acute intermittent porphyria, severe respiratory insufficiency, status asthmaticus, and conditions where general anesthesia is contraindicated.
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 specific food interactions reported for Surital (thiamylal). However, patients should avoid consuming grapefruit or grapefruit juice for 24 hours before and after administration, as it may theoretically inhibit cytochrome P450 metabolism, although significant interactions are not well-documented.
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).
Pregnancy Category D (positive evidence of human fetal risk). First trimester: Risk of congenital anomalies (limb defects, CNS malformations) based on animal studies and limited human data. Second/third trimester: Increased risk of preterm labor, fetal bradycardia, neonatal respiratory depression, and withdrawal syndrome. Avoid use during pregnancy unless clearly needed.
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.
Excretion into breast milk is unknown; M/P ratio not established. Due to high lipid solubility, potential for significant transfer. Consider risks of neonatal CNS depression. Use with caution; monitor infant for sedation, poor feeding, and respiratory depression. Alternative agents preferred.
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.
Increased volume of distribution and hepatic metabolism in pregnancy may require higher induction doses and more frequent maintenance doses. However, due to fetal risks, avoid use in pregnancy unless absolutely necessary. If used, start at lower range (e.g., 3-4 mg/kg IV induction) and titrate to effect. No established dose adjustment guidelines; individualize based on clinical response and close monitoring.
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.
Surital (thiamylal) is an ultra-short-acting barbiturate used for induction of anesthesia. Due to its high lipid solubility, onset of action is rapid (<30 seconds). It is contraindicated in porphyria and should be used with caution in patients with hepatic impairment, as it is metabolized in the liver. Extravasation causes tissue necrosis; use a large vein for IV administration. Respiratory depression and laryngospasm are common during induction. Surital has no analgesic properties and may cause myocardial depression at high doses. For short procedures, it provides rapid awakening but with potential residual sedation.
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.
This medication is used to put you to sleep before surgery or certain procedures.,You may feel dizzy or drowsy for several hours after receiving this drug; do not drive or operate machinery for at least 24 hours.,Avoid alcohol for at least 24 hours after receiving this medication as it can increase side effects.,Inform your healthcare provider if you have a history of porphyria, liver disease, or respiratory problems.,Do not breastfeed for at least 24 hours after administration without consulting your doctor.,Notify your doctor immediately if you experience severe pain, redness, or swelling at the injection site.,You may experience temporary confusion or memory loss after waking up; this is normal and should resolve.
