Immunomodulatory agent with anti-angiogenic and anti-proliferative properties; alters cytokine production, enhances T-cell and NK-cell activity, inhibits tumor angiogenesis, and directly induces apoptosis in tumor cells.
Adderall 12.5 is a combination of dextroamphetamine and amphetamine. It increases the levels of dopamine and norepinephrine in the central nervous system by inhibiting their reuptake and promoting their release from presynaptic neurons.
Multiple myeloma (in combination with dexamethasone),Myelodysplastic syndromes associated with deletion 5q,Mantle cell lymphoma (relapsed or refractory)
Attention deficit hyperactivity disorder (ADHD),Narcolepsy (off-label)
10 mg orally once daily on days 1-21 of 28-day cycle for transfusion-dependent anemia due to low- or intermediate-1-risk myelodysplastic syndromes; 25 mg orally once daily on days 1-21 of 28-day cycle for relapsed/refractory multiple myeloma.
5-60 mg orally once or twice daily; immediate-release: initial 5 mg once or twice daily, increase by 5 mg weekly; extended-release: initial 20 mg once daily in the morning, increase by 10 mg weekly.
Terminal half-life ~3 hours (range 2-5 h) in multiple myeloma patients; prolongation in renal impairment requires dose adjustment.
The terminal elimination half-life of d-amphetamine is approximately 10–13 hours in adults (range 9–14 h) and 6–8 hours in children. Clinical context: Typically allows twice-daily dosing; extended-release formulations provide 8–12 hours of effect.
Metabolized via hydrolysis and glucuronidation; CYP450 enzymes play a minor role.
Amphetamine and dextroamphetamine are extensively metabolized in the liver via CYP2D6 and other pathways. The primary metabolites are 4-hydroxyamphetamine and 4-hydroxynorephedrine.
Renal: ~82% unchanged; fecal <5%; biliary negligible.
Approximately 30% of the dose is excreted unchanged in urine; the remainder is metabolized primarily via deamination and oxidation. Renal elimination of unchanged amphetamine is p H-dependent: acidic urine increases elimination, alkaline urine decreases it. Fecal excretion accounts for <5%.
~30% bound, primarily to albumin.
Approximately 15–20% bound to plasma proteins, primarily albumin.
Approximately 0.6 L/kg (range 0.4-0.8 L/kg), indicating distribution into total body water.
Mean volume of distribution is 3.5–4.6 L/kg, indicating extensive tissue distribution. Clinical meaning: Large Vd reflects sequestration in tissues (including brain), contributing to prolonged presence.
Oral: ~80% (range 60-100%); food does not significantly affect absorption.
Oral bioavailability is highly variable, ranging from 75–100% for immediate-release tablets; food does not significantly affect overall absorption but may delay time to peak concentration. Extended-release capsules have bioavailability approximately 96% relative to immediate-release.
For Cr Cl 30-60 m L/min: 5 mg once daily; for Cr Cl <30 m L/min not requiring dialysis: 2.5 mg once daily; for Cr Cl <30 m L/min requiring dialysis: 2.5 mg once daily post-dialysis on dialysis days.
GFR 15-29 m L/min: reduce dose to 50% of usual; GFR <15 m L/min: use 50% of usual dose; hemodialysis: not removed, avoid use.
No specific dose adjustment for hepatic impairment in FDA labeling; use with caution in severe hepatic impairment (Child-Pugh C) due to lack of data.
Child-Pugh A: no adjustment; Child-Pugh B: use 50% of usual dose; Child-Pugh C: avoid use.
Not approved in pediatric patients; safety and efficacy not established in patients <18 years.
Immediate-release: 3-5 years: initial 2.5 mg once daily, increase by 2.5 mg weekly up to 40 mg/day; 6+ years: initial 5 mg once or twice daily, increase by 5 mg weekly up to 40 mg/day. Extended-release: 6-12 years: initial 10 mg once daily, increase by 10 mg weekly up to 30 mg/day; 13-17 years: initial 10 mg once daily, increase by 10 mg weekly up to 40 mg/day.
No specific dose adjustment beyond renal function; monitor for hematologic toxicity and thromboembolic events due to age-related comorbidities and renal impairment.
Start at lowest dose (5 mg immediate-release or 10 mg extended-release) and titrate slowly due to increased risk of adverse cardiovascular and CNS effects; monitor for hypertension, tachycardia, and agitation.
Embryo-fetal toxicity: Can cause fetal harm. Do not use during pregnancy. Females of reproductive potential must use contraception or abstain. Hematologic toxicity: Significant neutropenia and thrombocytopenia; monitor blood counts. Deep vein thrombosis and pulmonary embolism: Increased risk; monitor and consider prophylaxis.
Adderall has a high potential for abuse and dependence. Prolonged use may lead to drug dependence. Misuse may cause sudden death or serious cardiovascular adverse events.
Hematologic toxicity (neutropenia and thrombocytopenia); thromboembolic events; hepatotoxicity; allergic reactions; tumor lysis syndrome; thyroid disorders; neuropathy; increased risk of second primary malignancies.
Risk of abuse and dependence,Serious cardiovascular events including sudden death, stroke, and myocardial infarction,Blood pressure and heart rate increases,Psychiatric adverse events including exacerbation of pre-existing psychosis, mania, or aggression,Seizures in patients with seizure disorders,Visual disturbances,Growth suppression in children,Peripheral vasculopathy including Raynaud's phenomenon,Serotonin syndrome risk when used with serotonergic drugs
Pregnancy; hypersensitivity to lenalidomide; concomitant use with live vaccines; breastfeeding not recommended.
Known hypersensitivity to amphetamine products or other sympathomimetic amines,Concomitant use with MAOIs or within 14 days of MAOI therapy,Glaucoma,Hyperthyroidism,Agitated states,History of drug abuse,Cardiovascular disease including moderate to severe hypertension, advanced arteriosclerosis, symptomatic cardiovascular disease, or tachyarrhythmias
Avoid grapefruit, grapefruit juice, and Seville oranges (including marmalade) as they inhibit CYP3A4 and may increase lenalidomide exposure. No other significant food interactions. Take capsules with water; do not crush or chew.
Avoid acidic foods and beverages (e.g., citrus fruits, soda) within 1 hour of administration as they may decrease absorption. High-fat meals may delay absorption of extended-release formulations. Avoid caffeine and other stimulants. Grapefruit juice may increase amphetamine levels.
Lenalidomide is a thalidomide analogue; it is teratogenic in humans. Pregnancy category X. In the first trimester, there is a high risk of severe birth defects (e.g., limb defects, cardiac anomalies) and fetal death. No adequate studies in second or third trimester, but risk persists throughout pregnancy. Contraindicated in pregnancy.
First trimester: Increased risk of congenital malformations, particularly cardiovascular defects (e.g., septal defects) and oral clefts based on amphetamine exposure. Second and third trimesters: risk of preterm delivery, low birth weight, and neonatal withdrawal syndrome (irritability, feeding difficulties, respiratory distress). Premature delivery and growth restriction have been reported.
No data on lenalidomide in human milk; however, due to potential for serious adverse effects in nursing infants (including neutropenia and thrombocytopenia), breastfeeding is contraindicated during therapy and for at least 1 week after last dose. M/P ratio unknown.
Contraindicated due to potential for infant toxicity. M/P ratio not established; amphetamine is excreted into breast milk in small amounts but may accumulate in breastfeeding infants. Adverse effects include irritability, poor feeding, and decreased weight gain.
Lenalidomide is contraindicated in pregnancy; no dose adjustments are recommended because use is prohibited. No pharmacokinetic studies in pregnancy; however, physiological changes (e.g., increased volume of distribution, renal clearance) may alter drug levels, but given teratogenicity, dosing is not applicable.
Pharmacokinetics altered: increased hepatic metabolism and renal clearance in pregnancy may reduce amphetamine exposure; however, safety data do not support dose adjustment. Use lowest effective dose only if necessary; consider alternative non-amphetamine therapies.
Lenalidomide is an immunomodulatory drug (IMi D) with anti-angiogenic and anti-proliferative properties. It requires risk evaluation and mitigation strategy (REMS) due to teratogenicity. Monitor for thromboembolic events (DVT/PE) especially when combined with dexamethasone. Consider dose adjustment for renal impairment (Cr Cl < 60 m L/min). Baseline and periodic monitoring of CBC, thyroid function, and liver enzymes is essential. May cause tumor lysis syndrome in high tumor burden patients; ensure hydration and prophylaxis.
ADDERALL 12.5 mg is a fixed-dose combination of amphetamine and dextroamphetamine. Monitor for cardiovascular events, especially in patients with pre-existing heart conditions. Onset of action occurs within 30-60 minutes; duration of action is approximately 4-6 hours. Avoid late afternoon doses to prevent insomnia. Use with caution in patients with a history of drug abuse. May cause growth suppression in children; monitor height and weight. Do not crush or chew extended-release capsules.
Do not take lenalidomide if you are pregnant, breastfeeding, or planning to become pregnant; use two reliable forms of contraception during treatment and for 4 weeks after stopping.,Do not donate blood or sperm while taking lenalidomide and for 4 weeks after discontinuation.,Report any symptoms of blood clots (swelling, pain, redness in leg, sudden chest pain, shortness of breath) or signs of infection (fever, chills) immediately.,Take lenalidomide exactly as prescribed, usually once daily with a glass of water; do not break, chew, or open capsules.,Avoid grapefruit, grapefruit juice, and Seville oranges as they may affect drug metabolism.,Keep all appointments for blood tests to monitor for low blood cell counts and other side effects.

"The combination of lenalidomide and leflunomide may result in additive hematologic toxicity, particularly bone marrow suppression, due to overlapping mechanisms that impair hematopoietic cell proliferation and survival. Leflunomide, via its active metabolite teriflunomide, inhibits dihydroorotate dehydrogenase (DHODH) and suppresses pyrimidine synthesis in rapidly dividing cells, while lenalidomide modulates the ubiquitin E3 ligase cereblon, leading to altered cytokine production and direct antineoplastic effects. Clinically, patients may experience increased risks of severe neutropenia, thrombocytopenia, and anemia, potentially requiring dose reductions, growth factor support, or discontinuation of one agent."
"Digoxin, a cardiac glycoside, is a P-glycoprotein (P-gp) substrate. Lenalidomide, an immunomodulatory drug, can inhibit P-gp activity, leading to increased intestinal absorption and reduced renal clearance of digoxin. This interaction may cause elevated serum digoxin levels, increasing the risk of digoxin toxicity (e.g., arrhythmias, nausea, visual disturbances)."
"Lenalidomide, an immunomodulatory drug, increases the thrombogenic potential of Mestranol, an estrogen component of oral contraceptives, by enhancing platelet aggregation and endothelial activation. This combined prothrombotic effect elevates the risk of venous thromboembolism (VTE), including deep vein thrombosis and pulmonary embolism. Patients, especially those with additional risk factors, require careful monitoring for signs of thrombosis."
