ALYQ vs ANEXSIA 7.5/325
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.
Hydrocodone is a mu-opioid receptor agonist, producing analgesia and euphoria. Acetaminophen inhibits cyclooxygenase (COX) enzymes, reducing prostaglandin synthesis and providing analgesic and antipyretic effects.
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)
Management of moderate to moderately severe pain where treatment with an opioid is appropriate and for which alternative treatments are inadequate
Intravenous: 400 mg on Day 1, then 200 mg daily for 4 days; total 5 doses per cycle.
1 tablet (hydrocodone 7.5 mg / acetaminophen 325 mg) orally every 4 to 6 hours as needed for pain; maximum 6 tablets per day (hydrocodone 45 mg / acetaminophen 1950 mg).
Terminal elimination half-life is approximately 6-8 hours in adults with normal renal function; prolonged in renal impairment.
Hydrocodone: 3.8-4.5 hours (immediate-release). Acetaminophen: 2-3 hours. Clinical note: Half-life prolonged in hepatic impairment; requires dose adjustment.
Metabolized primarily by CYP3A4; also a substrate of P-glycoprotein. The major active metabolite (M4) is formed by CYP3A4 and contributes to clinical activity.
Hydrocodone: CYP3A4 and CYP2D6; Acetaminophen: primarily via glucuronidation (UGT1A1, UGT1A6, UGT1A9) and sulfation, with minor oxidation by CYP2E1.
Primarily renal excretion as unchanged drug (approximately 70-80%) and biliary/fecal elimination (20-30%) following intravenous administration.
Renal: ~90-100% as hydrocodone metabolites (conjugated) and unchanged hydrocodone; ~60% as acetaminophen metabolites (glucuronide, sulfate, cysteine); <5% unchanged acetaminophen. Biliary/fecal: <5%.
Approximately 30-40% bound to plasma proteins, primarily albumin.
Hydrocodone: ~20-30% (albumin). Acetaminophen: ~10-25% (albumin).
Volume of distribution is approximately 0.6-1.0 L/kg, indicating distribution into total body water and tissues.
Hydrocodone: 3-4 L/kg (extensive tissue distribution). Acetaminophen: ~1 L/kg (uniformly distributed).
Oral bioavailability is approximately 80-90%.
Oral: Hydrocodone ~70% (high first-pass metabolism); Acetaminophen ~85-90% (minimal first-pass).
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.
For GFR 30-59 m L/min: administer every 6 hours; maximum 4 tablets per day. For GFR 15-29 m L/min: administer every 8 hours; maximum 3 tablets per day. For GFR <15 m L/min: not recommended due to accumulation of metabolites.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 25%; Child-Pugh C: avoid use.
Child-Pugh Class A: no adjustment necessary. Child-Pugh Class B: reduce dose by 25-50% and extend dosing interval to every 6-8 hours; maximum 4 tablets per day. Child-Pugh Class C: contraindicated due to risk of hepatotoxicity.
Not established; safety and efficacy in pediatric patients not determined.
Not recommended for pediatric patients; safety and efficacy not established for children under 18 years. For adolescents ≥18 years: adult dosing.
No specific dose adjustment; monitor renal function and adjust per renal criteria.
Initiate at 1 tablet (hydrocodone 5 mg / acetaminophen 325 mg) every 6 hours as needed; titrate cautiously due to increased sensitivity, decreased renal function, and risk of respiratory depression. Maximum 4 tablets per day.
No FDA black box warning.
Addiction, abuse, and misuse; life-threatening respiratory depression; accidental ingestion; neonatal opioid withdrawal syndrome; risks from concomitant use with benzodiazepines or other CNS depressants; hepatotoxicity due to acetaminophen.

Risk of opioid addiction, abuse, and misuse; life-threatening respiratory depression; accidental ingestion; neonatal opioid withdrawal syndrome; risks from concomitant use of alcohol, benzodiazepines, or other CNS depressants; hepatotoxicity; severe hypotension; adrenal insufficiency; seizures; GI obstruction; impaired mental/physical abilities; use in elderly, cachectic, or debilitated patients; renal impairment; hepatic impairment; pregnancy; labor and delivery; nursing mothers; pediatric use; driving and operating machinery.
None known.
Significant respiratory depression; acute or severe bronchial asthma; known or suspected GI obstruction; hypersensitivity to hydrocodone or acetaminophen; concomitant use of MAOIs or within 14 days of such therapy.
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 alcohol consumption due to increased risk of acetaminophen hepatotoxicity and CNS depression. No specific food restrictions, but grapefruit juice may theoretically affect hydrocodone metabolism via CYP3A4 inhibition; however, clinical significance is uncertain.
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.
FDA Category C (hydrocodone) and Category D (acetaminophen) in third trimester. First trimester: Acetaminophen associated with rare gastroschisis; hydrocodone risk of neural tube defects. Second trimester: No major malformations except with prolonged opioid use. Third trimester: Acetaminophen safe; hydrocodone risk of neonatal opioid withdrawal syndrome (NOWS). Avoid near term.
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.
Hydrocodone/acetaminophen excreted in breast milk. M/P ratio unknown. Hydrocodone relative infant dose <3% of weight-adjusted maternal dose. Acetaminophen relative infant dose <2%. Use with caution; monitor infant for sedation, apnea, poor feeding. Highest risk in CYP2D6 ultrarapid metabolizers.
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.
Increased clearance of hydrocodone in pregnancy may require dose adjustment; monitor for inadequate analgesia. Acetaminophen pharmacokinetics unchanged. Avoid high doses (hepatotoxicity risk). Consider baseline hepatic function. No specific dose adjustment recommended; titrate to effect.
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.
ANEXSIA 7.5/325 (hydrocodone/acetaminophen) carries a boxed warning for acetaminophen hepatotoxicity; maximum acetaminophen dose from all sources should not exceed 4 g/day. Hydrocodone is metabolized by CYP2D6 to hydromorphone; ultrarapid metabolizers may experience toxicity. Avoid concurrent use with other CNS depressants including alcohol. Prescribe with caution in patients with renal impairment (hydrocodone accumulation) or hepatic impairment (acetaminophen toxicity). Monitor for signs of respiratory depression, especially at therapy initiation and dose titration. Use the lowest effective dose for the shortest duration.
