IDVYNSO is a selective dopamine D3 receptor antagonist, which modulates dopaminergic neurotransmission in the mesolimbic pathway.
Microtubule inhibitor that binds to tubulin and disrupts microtubule dynamics, leading to mitotic arrest and apoptosis.
Treatment of schizophrenia,Adjunctive treatment of major depressive disorder
Treatment of relapsed or refractory multiple myeloma,Treatment of relapsed or refractory mantle cell lymphoma
5 mg/kg IV once daily for 14 days; then 2.5 mg/kg IV once daily for 14 days.
Intravenous, 6 mg/kg every 4 weeks for 6 cycles; each cycle: Days 1 and 15 of a 28-day cycle.
Terminal elimination half-life is 12–18 hours, supporting twice-daily dosing in patients with normal renal function.
Terminal elimination half-life is 12-15 hours in patients with normal renal function; prolonged to 30-40 hours in severe renal impairment (Cr Cl <30 m L/min).
Primarily hepatic via CYP3A4 and CYP2D6
Primarily metabolized by CYP3A4 and to a lesser extent by CYP1A2 and CYP2C8.
Renal excretion of unchanged drug accounts for approximately 60% of elimination; biliary/fecal excretion accounts for 30%, with the remainder metabolized.
Primarily renal excretion of unchanged drug (60-70%) with biliary/fecal elimination accounting for 20-30%.
Approximately 85% bound, primarily to albumin and α1-acid glycoprotein.
Approximately 85-90% bound to serum albumin.
Vd = 1.5–2.5 L/kg, indicating extensive tissue distribution.
0.5 L/kg, indicating distribution primarily into extracellular fluid with limited tissue penetration.
Oral: 75–85% (first-pass effect minimal); intravenous: 100%.
Oral bioavailability is 50-60% due to first-pass metabolism and incomplete absorption.
Cr Cl >= 60 m L/min: no adjustment. Cr Cl 30-59: 2.5 mg/kg IV once daily for 28 days. Cr Cl < 30: not recommended.
GFR ≥30 m L/min: no adjustment. GFR <30 m L/min: not recommended (no data).
Child-Pugh A: no adjustment. Child-Pugh B: 2.5 mg/kg IV once daily for 28 days. Child-Pugh C: not recommended.
Child-Pugh A: no adjustment. Child-Pugh B or C: not recommended (no data).
Not approved for pediatric use. Safety and efficacy not established.
Not established; safety and efficacy not determined in pediatric patients.
No specific dose adjustment required; monitor renal function due to age-related decline. Use lowest effective dose.
No specific dose adjustment; monitor renal function and hematologic toxicity more frequently.
None
None.
May cause QT prolongation; monitor ECG. Risk of extrapyramidal symptoms. Caution in patients with hepatic impairment.
Hematologic toxicity (neutropenia, thrombocytopenia, anemia), infection risk, peripheral neuropathy, cardiotoxicity (heart failure), embryo-fetal toxicity.
Concurrent use with strong CYP3A4 inducers. History of QT prolongation or torsade de pointes.
Hypersensitivity to AURLUMYN or any of its components.
Avoid tyramine-rich foods: aged cheeses, cured meats (e.g., salami, pepperoni), fermented foods (e.g., sauerkraut, kimchi), soy products, broad bean pods, draft beers, and red wine. Tyramine can cause hypertensive crisis when combined with IDVYNSO.
Avoid alcohol. No specific food interactions, but maintain a balanced diet. Take with food or milk if gastrointestinal upset occurs.
Pregnancy Category X. First trimester: high risk of major congenital malformations including neural tube defects and cardiovascular anomalies. Second and third trimesters: risk of fetal growth restriction, oligohydramnios, and premature closure of the ductus arteriosus. Contraindicated in pregnancy.
First trimester: Increased risk of major congenital malformations (neural tube defects, cardiovascular anomalies) based on animal studies and limited human data. Second and third trimesters: Risk of fetal growth restriction, oligohydramnios, and preterm birth. Avoid in pregnancy unless benefit outweighs risk.
Excreted in human milk; M/P ratio not established. Potential for serious adverse reactions in nursing infants; discontinue breastfeeding or discontinue drug.
No data on excretion in human milk; M/P ratio unknown. Due to potential for serious adverse reactions in breastfed infants, breastfeeding is not recommended during treatment and for at least 2 weeks after last dose.
No dose adjustment recommended; use is contraindicated in pregnancy. Pharmacokinetic changes in pregnancy (increased clearance and volume of distribution) may require dosage increase if used for life-threatening conditions, but alternative therapy is preferred.
No specific dosing adjustments established for pregnancy. Pregnancy-induced pharmacokinetic changes (increased volume of distribution, enhanced renal clearance) may reduce drug exposure; consider therapeutic drug monitoring if available.
IDVYNSO is a reversible inhibitor of monoamine oxidase A (RIMA); avoid concurrent use with sympathomimetics and tyramine-rich foods. Monitor for hypertensive crisis; discontinue 5 days before elective surgery. Use with caution in patients with hepatic impairment.
AURLUMYN is a proprietary name for auranofin, an oral gold compound used for rheumatoid arthritis. Monitor for oral ulcerations, dermatitis, and proteinuria. Renal function and CBC should be checked monthly. Avoid concurrent use with penicillamine, antimalarials, immunosuppressants, or cytotoxic drugs. Onset of action may be delayed 3-6 months.
Do not take with other antidepressants, especially MAOIs, SSRIs, or SNRIs.,Avoid foods high in tyramine such as aged cheeses, cured meats, and fermented products.,Report sudden severe headache, palpitations, or chest pain immediately.,Take with food to minimize nausea; do not crush or chew tablets.,Do not stop abruptly; taper under medical supervision to avoid withdrawal symptoms.
Take exactly as prescribed; do not adjust dose without consulting your doctor.,Report any mouth sores, skin rash, unexplained bruising, or change in urine color immediately.,Regular blood and urine tests are required to monitor for side effects.,May take 3-6 months to feel full benefit; do not stop suddenly.,Avoid alcohol as it may increase risk of liver toxicity.,Use effective contraception during treatment and for 6 months after stopping.,Do not take any other medications (including OTC) without approval from your doctor.

IDVYNSO is a Antineoplastic Agent that works by IDVYNSO is a selective dopamine D3 receptor antagonist, which modulates dopaminergic neurotransmission in the mesolimbic pathway.. AURLUMYN is a Antineoplastic Agent that works by Microtubule inhibitor that binds to tubulin and disrupts microtubule dynamics, leading to mitotic arrest and apoptosis.. They differ in pharmacokinetic profiles, FDA-approved indications, and side effect profiles.
Potency comparisons between IDVYNSO and AURLUMYN depend on the specific clinical indication. These are both Antineoplastic Agent agents and are not directly interchangeable by dose. A physician or clinical pharmacist should guide any therapeutic switching decisions.
The standard adult dose of IDVYNSO is: 5 mg/kg IV once daily for 14 days; then 2.5 mg/kg IV once daily for 14 days.. The standard adult dose of AURLUMYN is: Intravenous, 6 mg/kg every 4 weeks for 6 cycles; each cycle: Days 1 and 15 of a 28-day cycle.. Dosing should always be individualized based on indication, renal and hepatic function, age, and other patient factors.
No direct drug-drug interaction has been formally documented between IDVYNSO and AURLUMYN in current clinical databases. However, individual patient risk factors including other medications, organ function, and comorbidities should always be evaluated by a qualified healthcare provider.
