Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
ANEXSIA is a combination of hydrocodone and acetaminophen. Hydrocodone is an opioid agonist that binds to mu-opioid receptors in the central nervous system, altering pain perception and emotional response to pain. Acetaminophen's analgesic mechanism is not fully understood but involves inhibition of COX enzymes in the CNS and modulation of descending serotonergic pathways.
Digitalis glycoside; inhibits Na+/K+-ATPase, increasing intracellular calcium and cardiac contractility.
Relief of moderate to moderately severe pain
Heart failure,Atrial fibrillation,Atrial flutter
50-100 mg orally every 4-6 hours as needed; maximum 400 mg/day.
0.05 to 0.2 mg intravenously or intramuscularly, administered slowly over 5 minutes; initial dose 0.15 to 0.2 mg, then 0.1 to 0.15 mg every 30 minutes up to a total of 0.4 mg. Oral: 0.05 to 0.2 mg daily for maintenance.
Terminal elimination half-life is 4-6 hours in adults with normal renal function; prolonged to 12-24 hours in severe renal impairment (Cr Cl <30 m L/min).
Terminal elimination half-life is 36-48 hours in patients with normal renal function; prolonged to >100 hours in severe renal impairment, requiring dose adjustment.
Hydrocodone is metabolized via CYP2D6 and CYP3A4 to hydromorphone and norhydrocodone. Acetaminophen is primarily metabolized via hepatic glucuronidation and sulfation; a minor pathway via CYP2E1 produces NAPQI, which is detoxified by glutathione.
Hepatic (minor); primarily renally excreted unchanged.
Approximately 70% renal (unchanged drug and metabolites), 20% biliary/fecal, 10% other.
Renal excretion of unchanged drug accounts for 60-70% of elimination; biliary/fecal excretion accounts for 30-40%, with enterohepatic circulation present.
Approximately 95% bound to plasma albumin and alpha-1-acid glycoprotein.
25-30% bound to plasma albumin.
0.2-0.4 L/kg, indicating limited extravascular distribution primarily confined to plasma and interstitial fluid.
6-10 L/kg; large Vd indicates extensive tissue distribution and high cardiac tissue affinity.
Oral: 80-90%; Intramuscular: 90-100%; Rectal: 70-80%.
Oral: 70-80%; IV: 100%.
GFR 30-89 m L/min: no adjustment; GFR 15-29 m L/min: 50% dose reduction; GFR <15 m L/min: avoid use.
GFR <50 m L/min: reduce dose by 50% or extend dosing interval to every 36-48 hours. GFR <10 m L/min: avoid use or reduce dose by 75%.
Child-Pugh A: no adjustment; Child-Pugh B: 50% dose reduction; Child-Pugh C: avoid use.
Child-Pugh Class A: no adjustment. Child-Pugh Class B: reduce dose by 25-50%. Child-Pugh Class C: avoid use or reduce dose by 75%.
1-2 mg/kg/dose orally every 6 hours; maximum 6 mg/kg/day.
Digitalizing dose: 0.01-0.02 mg/kg IV or IM, given in divided doses over 24 hours. Maintenance: 10-20% of digitalizing dose daily. Not recommended for neonates due to prolonged half-life.
Initiate at 25 mg every 6 hours; increase cautiously; monitor renal function.
Reduce dose by 25-50% due to decreased renal function and increased sensitivity. Monitor serum levels and renal function closely.
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 from acetaminophen.
Can cause potentially fatal arrhythmias; use only when clearly indicated and monitor serum levels.
Risk of respiratory depression, especially in elderly or debilitated patients; adrenal insufficiency; severe hypotension; seizures; opioid-induced hyperalgesia; acetaminophen hepatotoxicity (avoid exceeding 4 g/day); serotonin syndrome if used with serotonergic agents.
Narrow therapeutic index; toxicity risk increased with hypokalemia, hypomagnesemia, hypercalcemia, renal impairment; monitor ECG and drug levels.
Hypersensitivity to hydrocodone or acetaminophen; significant respiratory depression; acute or severe bronchial asthma in an unmonitored setting; known or suspected GI obstruction; severe hepatic impairment; concomitant use of MAOIs or within 14 days.
Ventricular fibrillation, digitalis toxicity, hypersensitivity, AV block (unless pacemaker present), Wolff-Parkinson-White syndrome.
Avoid alcohol; may increase risk of hepatotoxicity and GI bleeding. Limit caffeine intake from coffee, tea, cola, or energy drinks due to added caffeine content. High-fat meals may delay absorption; take on empty stomach for faster onset if tolerated.
Avoid licorice, which can cause hypokalemia. Maintain consistent intake of potassium-rich foods (bananas, oranges) to avoid fluctuations. No known significant food interactions beyond electrolyte effects.
First trimester: Data are limited; no increased risk of major malformations reported in small studies. Second and third trimesters: Associated with premature closure of the ductus arteriosus and oligohydramnios due to fetal renal effects; avoid use after 30 weeks gestation.
Pregnancy Category C. First trimester: No adequate human studies; animal studies show fetal risk. Second/third trimester: Risk of fetal bradycardia, cardiac glycoside toxicity; avoids if possible.
Excreted into breast milk in low concentrations (M/P ratio not established). Not recommended during breastfeeding due to potential for adverse effects in the infant, including renal impairment and gastrointestinal bleeding.
Deslanoside is excreted in breast milk; estimated infant dose 0.1-0.5% of maternal weight-adjusted dose; M/P ratio not well defined. Monitor infant for bradycardia, feeding difficulties; benefit likely outweighs risk.
Dose adjustment not generally required; however, due to increased renal clearance in pregnancy, shortened dosing intervals may be necessary for sustained efficacy. Use lowest effective dose for shortest duration.
Increased renal clearance in pregnancy may require higher doses; monitor serum drug levels and adjust accordingly. Reduced dosing in third trimester may be needed due to volume expansion.
ANEXSIA is a combination analgesic containing paracetamol, ibuprofen, and caffeine. It is contraindicated in patients with active peptic ulcer disease, severe hepatic impairment, or hypersensitivity to NSAIDs. Avoid concurrent use with other NSAIDs or paracetamol-containing products. Monitor renal function in elderly or dehydrated patients. Caffeine may exacerbate anxiety or insomnia.
Cedilanid-D (deslanoside) is a rapidly acting parenteral digitalis glycoside. Use with extreme caution in renal impairment due to reduced clearance. Monitor serum potassium and magnesium; hypokalemia and hypomagnesemia potentiate toxicity. Administer slow IV push over 5 minutes to avoid arrhythmias. Therapeutic drug monitoring less common due to short half-life of 33 hours. Contraindicated in ventricular tachycardia and AV block (unless due to atrial fibrillation).
Do not exceed recommended dose; overdosage of paracetamol can cause liver damage.,Take with food or milk to reduce gastrointestinal upset.,Avoid alcohol while taking this medication to reduce risk of liver toxicity and GI bleeding.,Discontinue use and consult if signs of allergic reaction, GI bleeding, or liver problems occur.,Caffeine may cause nervousness, insomnia, or increased heart rate; limit caffeine-containing foods and beverages.
Take exactly as prescribed; do not double doses.,Report symptoms of toxicity: nausea, vomiting, visual disturbances (yellow-green halos), irregular heartbeat.,Avoid over-the-counter medications without consulting doctor.,Maintain consistent potassium intake; avoid high-potassium foods or supplements unless advised.,Monitor daily weight and report rapid weight gain or edema.
