Clinical Essentials

ADDERALL 10
HARLIKU
Mechanism of Action
ADDERALL 10

Adderall 10 contains a mixture of amphetamine salts (dextroamphetamine and levoamphetamine). Amphetamines are non-catecholamine sympathomimetic amines that promote the release of dopamine and norepinephrine from presynaptic neurons, inhibit their reuptake, and inhibit monoamine oxidase activity, thereby increasing extracellular levels of these neurotransmitters in the central nervous system.

HARLIKU

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.

Indications
ADDERALL 10

Attention Deficit Hyperactivity Disorder (ADHD),Narcolepsy

HARLIKU

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

Standard Dosing
ADDERALL 10

10 mg orally once daily in the morning, with or without food; may increase by 5-10 mg weekly based on tolerability and response; usual effective dose 10-40 mg/day divided into 2-3 doses; maximum 60 mg/day.

HARLIKU

1 mg orally once daily.

Pharmacokinetics

ADDERALL 10
HARLIKU
Half-Life
ADDERALL 10

Terminal elimination half-life: dextroamphetamine 9-11 hours, levoamphetamine 11-14 hours (Adderall is a mixed salt). In adults, mean half-life ~10 hours; in children, slightly shorter (6-8 hours). Clinical context: steady-state reached in 2-3 days; dosing interval typically 4-6 hours for immediate-release.

HARLIKU

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.

Metabolism
ADDERALL 10

Amphetamine is metabolized primarily in the liver via cytochrome P450 enzymes, including CYP2D6, and undergoes deamination and oxidation to form inactive metabolites including 4-hydroxyamphetamine and norephedrine.

HARLIKU

Metabolized by catabolism into small peptides and amino acids.

Excretion
ADDERALL 10

Renal: 70-80% (30-40% as unchanged amphetamine; remainder as deaminated and hydroxylated metabolites). Fecal: minimal (<5%). Biliary: negligible. Urinary p H affects excretion: acidic urine increases elimination, alkaline urine decreases.

HARLIKU

Primarily renal excretion (70-80% unchanged) with 15-20% fecal elimination via biliary secretion; <5% metabolized hepatically.

Protein Binding
ADDERALL 10

Amphetamine: 15-40% bound to plasma proteins (primarily albumin). Binding is not extensive, thus significant free fraction available for distribution.

HARLIKU

Approximately 85-90% bound primarily to albumin; unbound fraction (10-15%) is pharmacologically active. Binding is saturable at supratherapeutic concentrations.

VD (L/kg)
ADDERALL 10

Apparent Vd: 3.0-4.0 L/kg (for total amphetamine). High Vd indicates extensive tissue distribution, including brain. Clinical meaning: loading dose may be needed for rapid effect; distribution half-life ~1 hour.

HARLIKU

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.

Bioavailability
ADDERALL 10

Oral immediate-release: 100% (well-absorbed; first-pass metabolism minimal). Food delays absorption but does not affect extent. Extended-release: bioavailability similar to immediate-release with modified release profile.

HARLIKU

Oral: 50–60% (fasting); reduced to 35–45% with high-fat meal. Subcutaneous: 90-95% (compared to IV). Intramuscular: 85-90%.
