Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
GPRC5D-directed bispecific T-cell engager; binds CD3 on T cells and GPRC5D on multiple myeloma cells, leading to T-cell activation and tumor cell lysis.
Adderall contains mixed amphetamine salts that increase synaptic levels of dopamine and norepinephrine by inhibiting their reuptake and promoting release from presynaptic terminals.
Relapsed or refractory multiple myeloma after at least 4 prior lines of therapy including an immunomodulatory agent, a proteasome inhibitor, and an anti-CD38 monoclonal antibody
Attention Deficit Hyperactivity Disorder (ADHD),Narcolepsy
1 mg orally once daily.
Initial: 5 mg orally once or twice daily; increase by 5 mg increments weekly; usual maintenance: 20-30 mg daily in divided doses; maximum: 40 mg/day
Terminal elimination half-life is approximately 12 hours (range 10–14 h) in patients with normal renal function; permits twice-daily dosing. Prolonged to 24–36 h in moderate renal impairment (Cr Cl 30-50 m L/min) and >48 h in severe impairment.
Terminal elimination half-life: d-amphetamine 10-13 hours, l-amphetamine 13-15 hours; in adults (children: 6-8 hours). The longer half-life allows for once-daily dosing.
Metabolized by catabolism into small peptides and amino acids.
Primarily hepatic via CYP2D6, with minor contributions from CYP1A2, CYP2B6, and CYP3A4.
Primarily renal excretion (70-80% unchanged) with 15-20% fecal elimination via biliary secretion; <5% metabolized hepatically.
Approximately 30-40% of a dose is excreted unchanged in urine; the remainder is metabolized primarily by oxidative deamination and aromatic hydroxylation. Biliary/fecal elimination accounts for less than 5%.
Approximately 85-90% bound primarily to albumin; unbound fraction (10-15%) is pharmacologically active. Binding is saturable at supratherapeutic concentrations.
Approximately 20-25% bound to plasma proteins, mainly albumin and alpha-1-acid glycoprotein.
Volume of distribution: 0.4–0.6 L/kg, indicating distribution primarily into extracellular fluid. Increased Vd (0.8–1.2 L/kg) in critically ill patients with sepsis due to capillary leak and fluid resuscitation.
Vd: 3-4 L/kg (approximately 210-280 L for a 70 kg adult). This indicates extensive tissue distribution and penetration into the central nervous system.
Oral: 50–60% (fasting); reduced to 35–45% with high-fat meal. Subcutaneous: 90-95% (compared to IV). Intramuscular: 85-90%.
Oral immediate-release: approximately 75-100%; oral extended-release: approximately 94% relative to immediate-release. Food does not significantly affect absorption but may delay peak concentration.
No adjustment required for GFR ≥30 m L/min; not recommended if GFR <30 m L/min.
GFR 30-89 m L/min: no adjustment; GFR 15-29 m L/min: reduce dose by 50%; GFR <15 m L/min: avoid use
Child-Pugh Class A: no adjustment; Child-Pugh Class B: reduce dose to 0.5 mg once daily; Child-Pugh Class C: not recommended.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: avoid use
Not approved for pediatric use; safety and efficacy not established.
Children 3-5 years: initial 2.5 mg orally once daily; increase by 2.5 mg weekly; usual range 2.5-20 mg/day. Children ≥6 years: initial 5 mg once or twice daily; increase by 5 mg weekly; usual range 5-40 mg/day in divided doses
No specific dose adjustment; monitor renal function and electrolyte levels closely.
Initiate at 2.5 mg orally once or twice daily; titrate slowly; monitor for cardiovascular effects, insomnia, and weight loss
Cytokine release syndrome (CRS) and neurologic toxicity (including immune effector cell-associated neurotoxicity syndrome, ICANS).
Amphetamines have a high potential for abuse and dependence. Misuse may cause sudden death or serious cardiovascular events.
Cytokine release syndrome; neurologic toxicity; infections; cytopenias; hepatotoxicity; embryo-fetal toxicity.
Risk of serious cardiovascular events including sudden death in patients with pre-existing structural cardiac abnormalities,Increased blood pressure and heart rate,Psychiatric adverse events including exacerbation of pre-existing psychosis, mania, or aggressive behavior,Serotonin syndrome risk when co-administered with serotonergic drugs,Long-term suppression of growth in children,Seizure risk in patients with history of seizures,Peripheral vasculopathy including Raynaud's phenomenon,Visual disturbances due to mydriasis
None.
Advanced arteriosclerosis,Symptomatic cardiovascular disease,Moderate to severe hypertension,Hyperthyroidism,Known hypersensitivity to amphetamines,Agitated states,History of drug abuse,During or within 14 days of MAO inhibitor use,Glaucoma
No significant food interactions; administer before the first meal of the day. Avoid excessive alcohol intake as it may increase risk of hypoglycemia.
Avoid high-fat meals as they delay absorption; avoid acidic foods (e.g., citrus) and vitamin C supplements within 1 hour of dosing as they decrease absorption; limit caffeine and other stimulants to avoid additive cardiovascular effects.
First trimester: Possible increased risk of congenital malformations (e.g., cardiac defects) based on animal studies and limited human data. Second and third trimesters: Risk of fetal growth restriction, oligohydramnios, and preterm birth. Avoid use unless benefit outweighs risk.
Pregnancy category C. First trimester: No well-controlled studies, but potential for congenital malformations not definitively established. Second and third trimesters: Increased risk of premature delivery, low birth weight, and neonatal withdrawal symptoms (e.g., dysphoria, agitation, lassitude). Chronic use may lead to neonatal toxicity.
Excreted in human milk; M/P ratio not established. Potential for adverse effects in nursing infant (e.g., diarrhea, rash). Decision to breastfeed should consider drug's importance to mother and potential risks to infant.
Excreted in breast milk. M/P ratio unknown. Potential for stimulant effects in infant (e.g., irritability, poor feeding, insomnia). Caution advised; consider alternative feeding methods.
Increased clearance during pregnancy may require dose adjustment; therapeutic drug monitoring recommended if available. Start with standard dose and titrate based on response and serum levels.
No established dosing guidelines. Due to increased plasma volume and clearance, dose may need titration to clinical effect, but avoid supratherapeutic doses. Use lowest effective dose.
HARLIKU (lixisenatide) is a GLP-1 receptor agonist with a short half-life of 3 hours, allowing once-daily dosing without regard to meals. Administer within 1 hour before the first meal of the day. Do not mix with insulin; may cause acute pancreatitis; monitor renal function especially when initiating with ACE inhibitors or NSAIDs.
For ADHD: start low, go slow; monitor weight and height in children; avoid late doses to prevent insomnia; check for abuse/diversion; screen for bipolar disorder and hypertension; consider urine drug screen before prescribing; avoid MAOIs within 14 days; use with caution in seizure disorders and glaucoma.
