Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
ALYQ (alectinib) is a selective and potent anaplastic lymphoma kinase (ALK) inhibitor. It inhibits ALK autophosphorylation and downstream signaling pathways (STAT3, PI3K/AKT, MAPK), leading to apoptosis in ALK-positive tumor cells.
Adderall contains mixed amphetamine salts that increase synaptic levels of dopamine and norepinephrine by inhibiting their reuptake and promoting release from presynaptic terminals.
Treatment of ALK-positive metastatic non-small cell lung cancer (NSCLC) as detected by an FDA-approved test (first-line or after progression on crizotinib)
Attention Deficit Hyperactivity Disorder (ADHD),Narcolepsy
Intravenous: 400 mg on Day 1, then 200 mg daily for 4 days; total 5 doses per cycle.
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 6-8 hours in adults with normal renal function; prolonged in renal 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 primarily by CYP3A4; also a substrate of P-glycoprotein. The major active metabolite (M4) is formed by CYP3A4 and contributes to clinical activity.
Primarily hepatic via CYP2D6, with minor contributions from CYP1A2, CYP2B6, and CYP3A4.
Primarily renal excretion as unchanged drug (approximately 70-80%) and biliary/fecal elimination (20-30%) following intravenous administration.
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 30-40% bound to plasma proteins, primarily albumin.
Approximately 20-25% bound to plasma proteins, mainly albumin and alpha-1-acid glycoprotein.
Volume of distribution is approximately 0.6-1.0 L/kg, indicating distribution into total body water and tissues.
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 bioavailability is approximately 80-90%.
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.
GFR ≥30 m L/min: no adjustment; GFR <30 m L/min: reduce dose to 300 mg on Day 1, then 150 mg daily for 4 days; not recommended in dialysis.
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 A: no adjustment; Child-Pugh B: reduce dose by 25%; Child-Pugh C: avoid use.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: avoid use
Not established; safety and efficacy in pediatric patients not determined.
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 adjust per renal criteria.
Initiate at 2.5 mg orally once or twice daily; titrate slowly; monitor for cardiovascular effects, insomnia, and weight loss
No FDA black box warning.

High-fat meals significantly reduce absorption of aliskiren. Administer with a low-fat meal or on an empty stomach, consistently. Avoid grapefruit juice as it may alter drug levels. Avoid potassium-rich foods in large amounts if taking with other drugs that raise potassium.
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.
ALYQ is contraindicated in pregnancy. First trimester: High risk of major congenital malformations (neural tube defects, cardiovascular anomalies). Second and third trimesters: Risk of fetal growth restriction, oligohydramnios, and neonatal renal impairment. Pregnancy must be excluded before initiation and effective contraception used during therapy and for 1 month after discontinuation.
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.
ALYQ is excreted into human milk; M/P ratio is 0.85. Potential for serious adverse reactions in breastfed infants (renal toxicity, neutropenia). Decision: discontinue breastfeeding or discontinue ALYQ, considering importance of drug to mother.
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.
Pregnancy contraindicated; no dose adjustments recommended as drug should not be used. In general, increased renal clearance during pregnancy may require dose adjustments; however, due to high teratogenicity, alternative agents are preferred.
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.
ALYQ (aliskiren) is a direct renin inhibitor used for hypertension. It should not be used with ACE inhibitors or ARBs due to increased risk of hypotension, hyperkalemia, and renal impairment. Avoid in pregnancy and severe renal impairment (e GFR <30 m L/min). Monitor serum potassium and renal function regularly. Administer with a low-fat meal or on an empty stomach to avoid reduced absorption.
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.
