Albendazole inhibits tubulin polymerization by binding to beta-tubulin, disrupting microtubule formation, which leads to impaired glucose uptake and depletion of glycogen stores in susceptible parasites, resulting in their immobilization and death.
Aripiprazole is a partial agonist at D2 and 5-HT1A receptors and an antagonist at 5-HT2A receptors, stabilizing dopamine and serotonin activity.

400 mg orally twice daily for 3-7 days for most indications; for neurocysticercosis, 400 mg orally twice daily for 8-30 days; for hydatid disease, 400 mg orally twice daily for 28-day cycles with 14-day drug-free intervals for 3 cycles.
400 mg IM once monthly after establishing tolerability with oral aripiprazole.
Terminal half-life of albendazole sulfoxide is 8–12 hours; parent drug half-life is <1 hour. Clinical context: supports once- or twice-daily dosing.
Aripiprazole: 75-146 hours; dehydro-aripiprazole: 94-146 hours. Long half-life allows monthly intramuscular dosing.
Primarily hepatic via microsomal enzymes; undergoes oxidation to albendazole sulfoxide (active metabolite) by CYP3A4 and flavin-containing monooxygenases (FMO). Further metabolized to albendazole sulfone (inactive) and other oxidative metabolites.
Primarily hepatic via CYP2D6 and CYP3A4; active metabolite dehydro-aripiprazole.
Primarily renal (80%) as inactive metabolites; <2% unchanged in urine. Biliary/fecal excretion accounts for ~20%.
Renal (approximately 25% unchanged and 55% as metabolites); fecal (approximately 20% as metabolites).
70% bound to plasma proteins, primarily albumin.
Aripiprazole is >99% bound to serum albumin and alpha-1-acid glycoprotein.
0.2–0.6 L/kg, indicating distribution into tissues; concentrates in liver, bile, and cerebrospinal fluid.
Aripiprazole: 4.9 L/kg (range 3.7-7.2 L/kg), indicating extensive tissue distribution.
Oral bioavailability is low (~5%) due to extensive first-pass metabolism; co-administration with a high-fat meal increases bioavailability up to 4–5-fold.
IM (Abilify Maintena): 100% relative to oral aripiprazole after 5 monthly doses; oral: 87%.

No adjustment for mild/moderate impairment; caution in severe impairment (Cr Cl <30 m L/min).
Contraindicated in patients with severe hepatic impairment (Child-Pugh class C). For mild to moderate impairment (Child-Pugh A or B), use with caution; monitor liver function. No specific dose adjustment guidelines available.
No adjustment for mild impairment; moderate to severe (Child-Pugh class B or C): reduce dose to 300 mg/month.
For children >2 years: 15 mg/kg/day orally in 2 divided doses (max 800 mg/day) for most indications. For neurocysticercosis: 15 mg/kg/day orally in 2 divided doses (max 800 mg/day) for 8-30 days. For hydatid disease: 15 mg/kg/day orally in 2 divided doses (max 800 mg/day) for 28-day cycles with 14-day drug-free intervals. For children <2 years: safety and efficacy not established.
Not approved for pediatric use.
No specific dose adjustment recommended; use with caution due to potential age-related hepatic or renal impairment. Monitor liver function and blood counts regularly.
Use cautiously due to increased sensitivity; consider lower doses and monitor for adverse effects.
Albendazole may cause fetal harm when administered to pregnant women. It is contraindicated in pregnancy and should not be used in women who are or may become pregnant. Women of childbearing potential should have a negative pregnancy test before starting treatment and should use effective contraception during therapy and for one month after completion.
Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death.
Bone marrow suppression: Monitor CBC at start and periodically; risk of pancytopenia, particularly in patients with hepatic disease or receiving high doses.,Hepatotoxicity: Monitor liver function tests due to risk of elevated transaminases and rare hepatic failure.,Risk of neurocysticercosis exacerbation: May cause increased intracranial pressure or seizures; treat with corticosteroids and anticonvulsants as needed.,Retinal damage: In ocular neurocysticercosis, evaluate for retinal lesions before therapy due to risk of retinal damage from inflammation.,Renal impairment: Use with caution; dose adjustment may be necessary.,Lactation: Excreted in breast milk; caution in nursing mothers.
Increased mortality in elderly dementia patients; suicidal thoughts and behaviors; neuroleptic malignant syndrome; tardive dyskinesia; metabolic changes (hyperglycemia, dyslipidemia, weight gain); orthostatic hypotension; leukopenia/neutropenia; seizure risk; dysphagia; body temperature dysregulation; pathological gambling and other impulse control disorders.
Pregnancy (absolute),Known hypersensitivity to albendazole or any of its components,Patients with pre-existing bone marrow suppression (relative)
Hypersensitivity to aripiprazole or any excipients in the formulation.
Take with a high-fat meal (≥40 g fat) to significantly increase oral bioavailability. Avoid grapefruit juice as it may affect drug metabolism. No specific dietary restrictions otherwise.
No specific food interactions. Grapefruit/grapefruit juice may increase aripiprazole levels (CYP3A4 inhibition). Avoid excessive alcohol consumption.
FDA Category C. First trimester: risk of skeletal abnormalities and embryotoxicity based on animal studies. Second and third trimesters: limited human data, but potential for fetal harm; avoid use unless benefit outweighs risk.
First trimester: Limited data, but aripiprazole is not a major human teratogen based on available studies. Second and third trimesters: Neonates exposed to antipsychotics, including aripiprazole, during the third trimester are at risk for extrapyramidal and/or withdrawal symptoms post-delivery.
Excreted in breast milk; M/P ratio not established. Use with caution, especially in neonates due to risk of bone marrow suppression.
Aripiprazole is excreted in human breast milk; the estimated infant dose is 0.7–1.4% of maternal weight-adjusted dose. M/P ratio: approximately 0.3–0.5. Limited data suggest no adverse effects in breastfed infants, but long-term safety is unknown.
No specific dose adjustment recommended in pregnancy; pharmacokinetic changes not well studied. Use lowest effective dose and shortest duration possible.
No specific dose adjustment recommended based on pharmacokinetic changes; however, therapeutic drug monitoring may be considered due to altered metabolism in pregnancy. The long-acting injectable formulation (Abilify Maintena) requires careful timing of doses postpartum to avoid relapse.
Albendazole is a broad-spectrum anthelmintic that inhibits microtubule polymerization by binding to beta-tubulin. It is highly effective against Echinococcus granulosus cysts but requires prolonged therapy (e.g., 28-day cycles). Monitor liver function tests (LFTs) at baseline and every 2 weeks due to risk of hepatotoxicity. For neurocysticercosis, co-administer corticosteroids to reduce inflammatory reaction from cyst degeneration. Albendazole is pregnancy category C; avoid in first trimester and in women planning pregnancy within 1 month of therapy. Absorption is enhanced by a fatty meal; administer with a high-fat meal to increase bioavailability up to 5-fold.
Administer every 4 weeks by intramuscular injection only. Do not substitute for oral aripiprazole on a mg-per-mg basis due to different pharmacokinetics. Requires initiation and continuation with oral aripiprazole for 14 days to establish tolerability. Monitor for neuroleptic malignant syndrome, tardive dyskinesia, and metabolic changes. Dose adjustments needed in patients with known CYP2D6 poor metabolizer status or concurrent use of strong CYP2D6 or CYP3A4 inhibitors.

"Albendazole inhibits the CYP3A4-mediated metabolism of clemastine, leading to increased plasma concentrations of clemastine. This can potentiate the anticholinergic and sedative effects of clemastine, including dry mouth, urinary retention, constipation, and drowsiness. Patients may experience heightened central nervous system depression, especially with concurrent use of other CNS depressants."
"Ranolazine, a piperazine derivative antianginal agent, is a moderate CYP3A4 inhibitor. Albendazole is primarily metabolized by CYP3A4 to its active metabolite, albendazole sulfoxide. Coadministration increases albendazole systemic exposure by approximately 50%, potentially enhancing both therapeutic efficacy and dose-dependent toxicities, including hepatotoxicity and bone marrow suppression."
"Albendazole inhibits CYP3A4, the enzyme primarily responsible for the metabolism of lovastatin. This inhibition reduces lovastatin clearance, leading to elevated plasma concentrations and increased risk of statin-related adverse effects such as myopathy, rhabdomyolysis, and hepatotoxicity. Patients receiving this combination should be monitored closely for signs of muscle pain or weakness and liver enzyme abnormalities."
