Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Allzital contains phenobarbital, a barbiturate that enhances GABA-A receptor activity by increasing the duration of chloride ion channel opening, leading to neuronal hyperpolarization and inhibition of neurotransmission.
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.

5-10 mg orally every 4-6 hours as needed for pain; not to exceed 40 mg per day.
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.
Terminal elimination half-life is 4-6 hours in healthy adults; prolonged to 8-12 hours in renal impairment.
Aripiprazole: 75 hours (range 48–146 h). Dehydro-aripiprazole: 94 hours (range 48–206 h). Steady state reached in 14 days.
Primarily hepatic via CYP2C9, CYP2C19, and glucuronidation; metabolized to inactive metabolites (e.g., p-hydroxyphenobarbital) that are excreted renally.
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.
Renal: 70% as unchanged drug; biliary/fecal: 20% as metabolites; 10% other.
Aripiprazole: ~25% renal, ~55% fecal; unchanged drug accounts for <1% renal. Dehydro-aripiprazole (active metabolite): excreted similarly.
92% bound to albumin and alpha-1-acid glycoprotein.
Aripiprazole: >99% bound to albumin and alpha-1-acid glycoprotein. Dehydro-aripiprazole: >99% bound.
2.5-3.5 L/kg; large Vd indicates extensive tissue distribution.
Aripiprazole: 4.9 L/kg (IV). High Vd indicates extensive tissue distribution.
Oral: 85-90% due to first-pass metabolism; intravenous: 100%.
Oral: 87% (absolute). Tablet and orally disintegrating tablet are bioequivalent.
GFR 30-50 m L/min: 50% dose reduction; GFR <30 m L/min: avoid use.
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.
Child-Pugh Class B: 50% dose reduction; Child-Pugh Class C: avoid use.
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.
0.1-0.2 mg/kg orally every 4-6 hours as needed; maximum single dose 5 mg; not to exceed 20 mg per day.
Not approved for patients <18 years; safety and effectiveness not established.
Initiate at 2.5 mg orally every 6 hours; titrate cautiously due to increased sensitivity and risk of respiratory depression.
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.
Risk of respiratory depression, particularly with rapid IV administration or excessive doses; co-administration with CNS depressants (e.g., opioids, alcohol) may exacerbate this effect. Use in pregnancy may cause fetal harm (teratogenic effects).
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.
Respiratory depression, CNS depression, dependence and withdrawal (taper gradually), paradoxical excitation (especially in elderly), use in hepatic or renal impairment, drug interactions with warfarin, oral contraceptives, and corticosteroids.

Hypersensitivity to barbiturates, severe respiratory insufficiency, history of porphyria, severe hepatic impairment, pregnancy (especially first trimester).
Hypersensitivity to aripiprazole or any component of the formulation,Concurrent use with ziprasidone (QT prolongation risk)
Avoid excessive alcohol consumption; may increase hepatotoxicity. No significant food interactions. Take with or without food; food may reduce GI upset.
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.
Allzital (butalbital/acetaminophen/caffeine) is category C. First trimester: risk of neural tube defects increased with barbiturate exposure; avoid. Second/third trimester: barbiturate use may lead to neonatal withdrawal and coagulation defects due to vitamin K deficiency; use only if benefit outweighs risk.
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).
Butalbital and acetaminophen are excreted into breast milk in low amounts. Caffeine also enters milk. M/P ratio not established for butalbital. Use caution; monitor infant for sedation, poor feeding. American Academy of Pediatrics considers butalbital compatible with breastfeeding but avoid prolonged use.
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 specific dose adjustments established for pregnancy. Pharmacokinetic changes (increased volume of distribution, hepatic metabolism) may reduce butalbital levels; clinical efficacy not well studied. Use lowest effective dose shortest duration. Acetaminophen doses remain standard (<4 g/day). Avoid caffeine >300 mg/day.
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.
ALLZITAL is a combination analgesic containing acetaminophen and tramadol. Monitor for serotonin syndrome when used with other serotonergic drugs. Avoid in patients with severe hepatic impairment or acute alcohol intoxication. Maximum daily acetaminophen dose is 4000 mg; reduce in hepatic risk. Tramadol may lower seizure threshold; use cautiously in epilepsy. Not recommended in breastfeeding due to tramadol excretion. Adjust dose in renal impairment (Cr Cl <30 m L/min: extended interval). Discontinue gradually to avoid withdrawal.
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.
Do not exceed 8 tablets per day due to acetaminophen liver risk.,Avoid alcohol and other acetaminophen-containing products.,May cause dizziness or drowsiness; avoid driving until effect known.,Report signs of serotonin syndrome (agitation, hallucinations, rapid heart rate).,Do not stop suddenly; taper to prevent withdrawal symptoms.,Store at room temperature away from moisture.,Use only as prescribed; risk of dependence with tramadol.
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.
