Microtubule inhibitor that binds to tubulin and disrupts microtubule dynamics, leading to mitotic arrest and apoptosis.
Agrylin (anagrelide) inhibits cyclic nucleotide phosphodiesterase III (PDE3) and reduces platelet production by interfering with megakaryocyte maturation and proliferation, likely via inhibition of cyclic AMP phosphodiesterase and modulation of intracellular calcium levels.
Treatment of relapsed or refractory multiple myeloma,Treatment of relapsed or refractory mantle cell lymphoma

None.
None
Hematologic toxicity (neutropenia, thrombocytopenia, anemia), infection risk, peripheral neuropathy, cardiotoxicity (heart failure), embryo-fetal toxicity.
Cardiovascular risks: increased risk of ventricular tachycardia, QTc prolongation, and heart failure; use caution in patients with known cardiac disease.,Hematologic effects: monitor complete blood counts regularly due to risk of anemia, leukopenia, or thrombocytopenia.,Hepatic impairment: reduce dose in patients with moderate to severe hepatic impairment.,Renal impairment: use with caution in severe renal impairment.
Hypersensitivity to AURLUMYN or any of its components.
Severe hepatic impairment,Known hypersensitivity to anagrelide or any component of the formulation
Avoid alcohol. No specific food interactions, but maintain a balanced diet. Take with food or milk if gastrointestinal upset occurs.
Grapefruit and grapefruit juice should be avoided as they may increase anagrelide plasma concentrations. No other specific dietary restrictions; however, maintain adequate hydration to reduce risk of crystalluria.
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.
Pregnancy Category C. Anagrelide is not recommended in pregnancy. Animal studies have shown embryotoxicity and teratogenicity (e.g., increased fetal resorptions, skeletal anomalies) at doses less than the human therapeutic dose. There are no adequate and well-controlled studies in pregnant women. Use only if potential benefit justifies potential risk to fetus. First trimester: Avoid due to organogenesis risk. Second and third trimesters: Unknown risks; consider alternative therapy.
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.
It is not known whether anagrelide is excreted in human milk. No M/P ratio is available. Due to potential for serious adverse reactions in breastfed infants (e.g., thrombocytopenia, cardiovascular effects), advise women not to breastfeed during treatment and for at least 7 days after last dose.
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.
No specific pharmacokinetic studies in pregnancy. Pregnancy-induced plasma volume expansion may lower drug concentrations, potentially requiring dose adjustment to maintain therapeutic effect. However, due to teratogenicity risks, avoid use in pregnancy. If necessary, start at lowest effective dose (0.5 mg/day) and titrate based on platelet count monitoring, not to exceed 10 mg/day.
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.
Agrylin (anagrelide) is a phosphodiesterase III inhibitor used to reduce platelet counts in essential thrombocythemia. Monitor platelet count weekly during titration; target <600,000/µL. Avoid in patients with severe hepatic impairment (Child-Pugh C). Use with caution in cardiac disease due to risk of QT prolongation and arrhythmias. Anagrelide may increase bleeding risk, especially when combined with anticoagulants or NSAIDs. Discontinue 4-5 days before elective surgery.

Common clinical questions about AURLUMYN vs AGRYLIN, answered by our medical review team.
AURLUMYN is a Antineoplastic Agent that works by Microtubule inhibitor that binds to tubulin and disrupts microtubule dynamics, leading to mitotic arrest and apoptosis.. AGRYLIN is a Antineoplastic Agent that works by Agrylin (anagrelide) inhibits cyclic nucleotide phosphodiesterase III (PDE3) and reduces platelet production by interfering with megakaryocyte maturation and proliferation, likely via inhibition of cyclic AMP phosphodiesterase and modulation of intracellular calcium levels.. They differ in pharmacokinetic profiles, FDA-approved indications, and side effect profiles.
Potency comparisons between AURLUMYN and AGRYLIN 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 AURLUMYN is: Intravenous, 6 mg/kg every 4 weeks for 6 cycles; each cycle: Days 1 and 15 of a 28-day cycle.. The standard adult dose of AGRYLIN is: Adults: 0.5 mg orally once or twice daily, increased by 0.5 mg every 2 weeks to maintain platelet count <600,000/µL. Maximum dose: 10 mg/day.. 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 AURLUMYN and AGRYLIN 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.
The maternal-fetal safety profiles differ. AURLUMYN is classified as Category C. First trimester: Increased risk of major congenital malformations (neural tube defects, cardiovascular anomalies) based on animal studies and limited human data. Second and third t. AGRYLIN is classified as Category C. Pregnancy Category C. Anagrelide is not recommended in pregnancy. Animal studies have shown embryotoxicity and teratogenicity (e.g., increased fetal resorptions, skeletal anomalies. Always consult a maternal-fetal medicine specialist before taking either drug during pregnancy or lactation.
