Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Desoxycorticosterone acetate (DOCA) is a mineralocorticoid hormone that binds to mineralocorticoid receptors in the distal renal tubules, promoting sodium reabsorption and potassium excretion, leading to increased extracellular fluid volume and blood pressure.
Hydrocodone is a semi-synthetic opioid agonist that binds to mu-opioid receptors in the CNS, inhibiting ascending pain pathways and altering pain perception. Acetaminophen is a para-aminophenol derivative with analgesic and antipyretic effects, primarily through central COX-2 inhibition and activation of descending serotonergic pathways.
Adrenocortical insufficiency (Addison's disease),Salt-losing adrenogenital syndrome
Management of moderate to moderately severe pain where an opioid analgesic is appropriate
Desoxycorticosterone acetate (DOCA) is administered intramuscularly at a dose of 2 to 5 mg daily or 10 mg every 12 hours initially, then reduced to 1 to 2 mg daily or every other day for maintenance. Alternatively, a pellet implant of 125 mg or 250 mg can be used for prolonged effect.
1-2 tablets orally every 4-6 hours as needed for pain; maximum 8 tablets per day.
30-35 minutes; clinical context: short duration necessitates frequent dosing or continuous infusion for sustained effect.
Oxycodone: terminal half-life 3.2-4.3 hours (immediate-release); prolonged in hepatic impairment. Acetaminophen: terminal half-life 2-3 hours (therapeutic doses); prolonged in hepatic impairment or overdose.
Primarily hepatic metabolism via reduction and conjugation; little is known about specific CYP enzymes.
Hydrocodone: primarily hepatic via CYP3A4 and CYP2D6 to active metabolites (hydromorphone). Acetaminophen: hepatic metabolism via conjugation (glucuronidation, sulfation) and CYP2E1-mediated oxidation to toxic NAPQI.
Primarily renal as metabolites; <5% unchanged. Biliary/fecal elimination is negligible (<2%).
Oxycodone: renal excretion of metabolites (conjugated and unconjugated) and parent drug; ~10% excreted unchanged. Acetaminophen: renal excretion of metabolites (glucuronide and sulfate conjugates); ~2-4% excreted unchanged.
~70% bound to plasma proteins (primarily albumin).
Oxycodone: 38-45% bound to albumin and alpha-1-acid glycoprotein. Acetaminophen: 10-25% bound to albumin at therapeutic concentrations.
Vd: 0.8-1.2 L/kg; indicates extensive tissue distribution with rapid redistribution from effect sites.
Oxycodone: Vd 2.0-3.0 L/kg; distributes extensively into tissues. Acetaminophen: Vd 0.8-1.0 L/kg; relatively uniform distribution.
Oral: <5% due to extensive first-pass metabolism; IM/SC: 100%.
Oxycodone: oral bioavailability 60-87% (immediate-release). Acetaminophen: oral bioavailability 88-98% (therapeutic doses).
No specific dose adjustment is recommended for impaired renal function, but monitor for fluid retention and hypertension. Use with caution in patients with significant renal impairment.
GFR 30-50 m L/min: use with caution, increase dosing interval to every 6 hours; GFR <30 m L/min: avoid use due to hydrocodeone accumulation.
No specific dose adjustment for hepatic impairment, but use with caution due to potential electrolyte disturbances.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50% and monitor; Child-Pugh C: contraindicated.
Dose is not well established; use 0.1 to 0.2 mg/kg intramuscularly daily or adjust based on clinical response and serum electrolytes.
Not recommended for children under 18 years due to risk of respiratory depression.
Start at the lower end of the dosing range (e.g., 1 to 2 mg IM daily) and monitor closely for fluid overload, hypertension, and electrolyte imbalances due to age-related decreased renal function and comorbidities.
Start with lowest dose (1 tablet every 6 hours), monitor renal and hepatic function, and avoid in frail elderly due to increased fall and cognitive impairment risk.

No specific food interactions are reported. However, maintain consistent sodium intake; do not restrict salt unless advised. Avoid potassium-rich foods if potassium levels are high. Alcohol may increase the risk of electrolyte disturbances.
Avoid alcohol. Grapefruit juice may enhance side effects; limit intake. Take with food to reduce gastrointestinal discomfort.
FDA Pregnancy Category C. First trimester: feminization of male fetuses, including hypospadias and clitoral hypertrophy, due to androgenic activity. Second and third trimesters: risk of virilization of female fetuses; no adequate human studies; avoid use unless potential benefit outweighs risk.
First trimester: Associated with increased risk of neural tube defects and cardiovascular malformations; avoid use. Second and third trimesters: Chronic exposure may cause fetal renal toxicity, oligohydramnios, and premature closure of ductus arteriosus. Use only if clearly needed.
Excreted in breast milk in low amounts; M/P ratio not established. Potential for adverse effects in nursing infants (e.g., electrolyte disturbances, hypertension). Use caution; consider alternative therapies.
Paracetamol and hydrocodone are excreted in breast milk. M/P ratio: paracetamol ~1.0, hydrocodone ~1.0-2.0. Use with caution; monitor infant for drowsiness and respiratory depression. Consider risk of infant sedation with long-term use.
No specific dose adjustments studied; monitor for increased volume of distribution and clearance; adjust based on clinical response and serum electrolyte levels. Use lowest effective dose.
Increased clearance in pregnancy may require dose adjustment. Monitor for pain control and adverse effects; no fixed dose change recommended. Consider lower starting dose due to potential fetal risks. Avoid chronic use; taper if possible.
DOCA (desoxycorticosterone acetate) is a mineralocorticoid used in adrenal insufficiency. Monitor serum potassium closely due to risk of hypokalemia from excessive mineralocorticoid activity. DOCA requires intramuscular injection; do not administer intravenously. Use in conjunction with glucocorticoids to mimic cortisol's permissive effects on catecholamines. Avoid in patients with hypertension, heart failure, or renal impairment due to sodium and water retention.
ANEXSIA 5/325 contains hydrocodone 5 mg and acetaminophen 325 mg. Maximum acetaminophen dose from all sources should not exceed 4 g/day in adults; avoid in severe hepatic impairment. Hydrocodone is a Schedule II controlled substance with abuse potential; monitor for respiratory depression, especially in opioid-naive patients. Use with caution in patients with COPD, sleep apnea, or increased intracranial pressure. Consider naloxone co-prescription for high-risk patients. For acute pain, limit duration to 3-7 days.

"Lidocaine, a sodium channel blocker and Class IB antiarrhythmic, inhibits hepatic CYP3A4, the primary enzyme responsible for the metabolism of quazepam, a benzodiazepine sedative-hypnotic. This inhibition reduces quazepam clearance, leading to elevated serum concentrations and enhanced sedative effects. Clinically, this may result in excessive sedation, respiratory depression, psychomotor impairment, and increased risk of falls, especially in elderly patients or those with hepatic impairment."
"Lidocaine and prilocaine are both amide-type local anesthetics that block voltage-gated sodium channels in neuronal membranes, inhibiting nerve impulse propagation. When used together, their systemic absorption can lead to additive cardiovascular and central nervous system toxicity, including arrhythmias, seizures, and methemoglobinemia, particularly with high doses or in patients with predisposing conditions."
"Lidocaine, a class Ib antiarrhythmic, inhibits CYP3A4, the primary enzyme responsible for the metabolism of ticagrelor, a P2Y12 platelet inhibitor. This inhibition can lead to increased plasma concentrations of ticagrelor, potentiating its antiplatelet effect and elevating the risk of major bleeding, such as gastrointestinal or intracranial hemorrhage. Conversely, reduced ticagrelor metabolism may also affect conversion to its active metabolite, though net effect still increases overall antiplatelet activity."
