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.
Isolyte E in Dextrose 5% provides fluid, electrolytes, and calories. Dextrose is metabolized to carbon dioxide and water, yielding energy. Electrolytes (sodium, potassium, magnesium, chloride, acetate, gluconate) maintain acid-base balance and osmotic pressure.
Adrenocortical insufficiency (Addison's disease),Salt-losing adrenogenital syndrome
FDA-approved: For intravenous administration as a source of water, electrolytes, and calories in patients requiring fluid and electrolyte replacement.,Off-label: Not typically used off-label; primarily for maintenance or replacement therapy.
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.
Intravenous infusion; typical adult dose is 1000-2000 m L per day (30 m L/kg/day) adjusted for fluid and electrolyte needs; rate based on clinical status.
30-35 minutes; clinical context: short duration necessitates frequent dosing or continuous infusion for sustained effect.
Not applicable; components are endogenous substances. Dextrose half-life ~15-20 min after infusion; electrolytes distribute and are cleared renally with half-lives dependent on renal function.
Primarily hepatic metabolism via reduction and conjugation; little is known about specific CYP enzymes.
Dextrose undergoes glycolysis and the citric acid cycle; electrolytes are not metabolized but are excreted or incorporated into body pools.
Primarily renal as metabolites; <5% unchanged. Biliary/fecal elimination is negligible (<2%).
ISOLYTE E in Dextrose 5% is a balanced electrolyte solution with glucose. Electrolytes are primarily excreted renally; water and dextrose are metabolized. Biliary/fecal excretion is negligible. Dextrose is metabolized to CO2 and water.
~70% bound to plasma proteins (primarily albumin).
None for electrolytes and dextrose; sodium, potassium, chloride, magnesium, acetate, and gluconate are free ions in solution.
Vd: 0.8-1.2 L/kg; indicates extensive tissue distribution with rapid redistribution from effect sites.
Sodium and chloride distribute primarily in extracellular fluid (~0.2 L/kg). Dextrose distributes in total body water (~0.6 L/kg). Potassium distributes in intracellular fluid (~0.6 L/kg after equilibration).
Oral: <5% due to extensive first-pass metabolism; IM/SC: 100%.
100% intravenous; not administered by other routes.
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.
In renal impairment (e GFR < 30 m L/min/1.73m²), reduce total volume to 500-1000 m L/day with careful monitoring of potassium, sodium, and glucose; avoid if hyperkalemia or fluid overload.
No specific dose adjustment for hepatic impairment, but use with caution due to potential electrolyte disturbances.
No specific dose adjustment for Child-Pugh class; monitor for fluid overload and electrolyte imbalances; in severe hepatic impairment, reduce volume to 500-1000 m L/day.
Dose is not well established; use 0.1 to 0.2 mg/kg intramuscularly daily or adjust based on clinical response and serum electrolytes.
Weight-based: 20-50 m L/kg/day for maintenance; neonates and infants: 100-150 m L/kg/day; adjust based on glucose, electrolytes, and hydration status; maximum rate 4 m L/kg/hour for neonates.
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 lower volumes (500-1000 m L/day) due to decreased renal function and risk of fluid overload; monitor serum electrolytes, glucose, and central venous pressure.

Hypersensitivity to desoxycorticosterone or any component,Severe renal impairment,Hyperkalemia,Hypocalcemia,Congestive heart failure,Systemic fungal infections
Hypersensitivity to any component; clinically significant hyperglycemia; severe metabolic acidosis; hyperkalemia (for potassium-containing formulations); hypermagnesemia; fluid overload conditions.
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.
No specific food interactions known. Monitor electrolyte intake in patients with electrolyte imbalances.
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.
ISOLYTE E in Dextrose 5% is an intravenous electrolyte and carbohydrate solution. There are no adequate and well-controlled studies in pregnant women. Animal reproduction studies have not been conducted. Dextrose and electrolytes are considered essential nutrients and are generally safe when used as indicated. However, administration during labor and delivery may cause fluid and electrolyte imbalances. First trimester risks are theoretical; second and third trimesters may involve risks of maternal hyperglycemia and fetal hyperinsulinemia if dextrose infusion is excessive. No specific teratogenicity reported.
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.
Dextrose and electrolytes are normal constituents of human milk. Following intravenous administration, concentrations in milk are expected to parallel maternal plasma levels. No specific M/P ratio is available. Use during breastfeeding is considered compatible; however, monitor for adverse effects in the infant such as electrolyte imbalance or hyperglycemia if maternal infusion is prolonged or high volume.
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.
Pregnancy induces increased plasma volume and glomerular filtration rate, potentially diluting electrolytes and altering glucose metabolism. Dose adjustments may be required: consider lower dextrose infusion rates to avoid maternal hyperglycemia and fetal hyperinsulinemia. Monitor electrolytes closely; adjust potassium and magnesium supplementation as needed. No specific dose adjustment is universally recommended; individualize based on maternal weight, clinical status, and monitoring results.
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.

"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."
