Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Akovaz (ephedrine sulfate) is a sympathomimetic amine that directly stimulates alpha- and beta-adrenergic receptors, and indirectly by releasing norepinephrine from presynaptic terminals, leading to increased heart rate and contractility, and vasoconstriction.
Isolyte E with Dextrose 5% provides isotonic fluid, electrolytes (sodium, potassium, magnesium, chloride, acetate, gluconate), and calories (dextrose). Dextrose supplies glucose for cellular energy, electrolytes maintain acid-base balance and osmotic pressure, and acetate/gluconate serve as bicarbonate precursors to correct metabolic acidosis.
Treatment of clinically important hypotension occurring in the setting of anesthesia
Fluid and electrolyte replacement in patients with normal or mildly depleted intravascular volume,Treatment and prevention of hypokalemia,Metabolic acidosis correction,Caloric supplementation when peripheral parenteral nutrition is indicated
5 mg intravenously once daily.
Intravenous infusion; dose based on electrolyte deficits and maintenance requirements; typical adult maintenance: 50-100 m L/hour, up to 2-3 L/day.
Terminal elimination half-life: 3-4 hours, prolonged in renal impairment (up to 8-12 hours in severe CKD).
Not applicable (dextrose and electrolytes are endogenous substances; distribution and elimination are rapid, with a functional half-life of minutes to hours depending on infusion rate and renal function).
Hepatic metabolism via oxidative deamination and demethylation; primarily metabolized by CYP2D6; some metabolites are active.
Dextrose is metabolized via glycolysis and the citric acid cycle. Acetate is metabolized primarily in the liver and muscle to bicarbonate. Gluconate is converted to glucose or metabolized via the pentose phosphate pathway.
Renal: ~70% unchanged; biliary/fecal: ~30% as metabolites and unchanged drug.
Renal: 100% (as free water and electrolytes, not metabolized). Biliary/Fecal: negligible.
85% bound to albumin and alpha-1-acid glycoprotein.
Negligible (<5%) for dextrose and electrolytes; no specific binding proteins.
Vd: 1.5-2.0 L/kg, indicating extensive tissue distribution.
Dextrose: ~0.2 L/kg (total body water); Electrolytes: ~0.4 L/kg (extracellular fluid). Clinical meaning: distributes throughout total body water.
Oral: 75% (first-pass metabolism minimal).
Intravenous: 100%.
Not required as AKOVAZ is not renally excreted.
Monitoring of electrolytes and volume status required; dosage adjustment not standardized; avoid in severe renal impairment (e GFR <30 m L/min/1.73 m²) due to risk of hyperkalemia and fluid overload.
No dose adjustment needed based on Child-Pugh classification.
No specific adjustment recommended; monitor electrolytes and acid-base balance; caution in severe hepatic impairment due to altered fluid clearance.
0.1 mg/kg intravenously once daily, maximum 5 mg.
Weight-based: 100-150 m L/kg/day for maintenance; adjust for ongoing losses; use with caution in neonates and children with renal impairment.
No specific dose adjustment required; use caution due to potential age-related decreased renal function.
Consider reduced starting rates due to decreased renal function and increased risk of fluid overload; monitor electrolytes and volume status closely; adjust rate based on comorbidities.
None
NOT FOR USE IN HYPERLACTATEMIA, SEVERE METABOLIC ALKALOSIS, OR SEVERE HEPATIC FAILURE; CONTAINS ALUMINUM WHICH MAY BE TOXIC WITH PROLONGED USE IN RENAL IMPAIRMENT; ADDITIVES MAY BE INCOMPATIBLE, CONSULT PHARMACIST.
Hypertension: May cause severe hypertension, including hypertensive crisis, especially with concurrent MAOIs or other vasopressors.,Arrhythmias: May induce ventricular arrhythmias, especially in patients with underlying cardiac disease.,Risk of stroke: Hypertensive effects may increase risk of intracranial hemorrhage.,Tachyphylaxis: Repeated use may lead to decreased response.,Extravasation: Risk of tissue necrosis if extravasation occurs.,Use caution in patients with hyperthyroidism, pheochromocytoma, or diabetes.
Monitor serum electrolytes, fluid balance, and blood glucose. Use with caution in patients with heart failure, renal impairment, hepatic disease, or hyperglycemia. Hypersensitivity reactions may occur. Avoid rapid or large-volume infusion in patients with impaired glucose tolerance.
Hypersensitivity to ephedrine or other sympathomimetics,Concurrent use with MAOIs or within 14 days after discontinuation,Angle-closure glaucoma,Severe hypertension or cardiovascular disease
Hypernatremia, hyperkalemia, hypermagnesemia, hypercalcemia, hyperlactatemia, severe metabolic alkalosis, severe hepatic failure, hyperglycemic states, anuria, or known hypersensitivity to any component.
No known food interactions. This drug is administered intravenously, so dietary restrictions are not applicable. However, oral intake should not interfere with therapy.
No known food interactions. However, patients with diabetes should be aware of dextrose content which affects blood glucose. Dietary potassium or magnesium restriction may be necessary if electrolyte imbalances occur.
Akovaz (ephedrine sulfate) is classified as FDA Pregnancy Category C. In first trimester, there is insufficient human data; animal studies show teratogenic effects at high doses. In second and third trimesters, use may cause fetal tachycardia, reduced uteroplacental blood flow, and potential for neonatal withdrawal or toxicity. Risk of maternal hypertension and decreased uterine perfusion outweighs benefits unless clearly indicated.
No evidence of teratogenicity in animal studies or human data. Dextrose and electrolytes are essential nutrients; no structural anomalies attributed. However, hyperglycemia in uncontrolled maternal diabetes may cause fetal malformations. Use cautiously in gestational diabetes.
Ephedrine is excreted into breast milk. The milk-to-plasma (M/P) ratio is approximately 2.5-3.0. Peak milk concentration occurs 1-2 hours after dose. Potential for infant stimulation, irritability, and sleep disturbances. Use with caution; monitor infant for adverse effects. Avoid in lactation if possible or use lowest effective dose for shortest duration.
Dextrose and electrolytes pass into breast milk but are normal milk constituents. No adverse effects expected in term infants. M/P ratio not determined as these are endogenous substances. Consider maternal fluid/electrolyte status.
Pharmacokinetic changes in pregnancy (increased plasma volume, altered binding proteins) may reduce peak concentrations of ephedrine. However, no specific dose adjustment recommendations are established for Akovaz in pregnancy. Use the lowest effective dose to achieve desired effect (typically 5-10 mg IV for hypotension). Monitor clinical response closely; dose titration may be needed due to altered sensitivity of adrenergic receptors in pregnancy. Avoid prolonged use.
No specific dose adjustment needed. Monitor for volume expansion in pregnancy (increased intravascular space). Adjust rate based on maternal glucose, electrolytes, and clinical response. Avoid excess dextrose in gestational diabetes.
AKOVAZ (ceftolozane/tazobactam) is a cephalosporin/beta-lactamase inhibitor combination used primarily for hospital-acquired pneumonia and complicated urinary tract infections. Monitor renal function closely; dose adjustment required for Cr Cl < 50 m L/min. Administer intravenously over 1 hour. Observe for hypersensitivity reactions, including anaphylaxis, particularly in penicillin-allergic patients. Consider cross-reactivity with other beta-lactams. Collect cultures before initiation.
ISOLYTE E W/ DEXTROSE 5% is an isotonic, balanced electrolyte solution with 5% dextrose for parenteral replacement of fluid and electrolytes. It contains potassium, magnesium, and acetate (bicarbonate precursor). Avoid in patients with hyperkalemia, hypermagnesemia, or metabolic alkalosis. Monitor serum electrolytes, glucose, and renal function. Use with caution in heart failure, renal impairment, and patients at risk for fluid overload. Do not administer if cloudy or precipitate present. Discard any unused portion.
