Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
ISOLYTE E is an intravenous electrolyte replacement solution that provides water, electrolytes (sodium, potassium, magnesium, calcium, chloride, acetate, and gluconate), and bicarbonate precursors to correct fluid and electrolyte imbalances. The acetate and gluconate ions are metabolized to bicarbonate in the liver, providing an alkaline buffer.
ZEGALOGUE (dasiglucagon) is a glucagon receptor agonist that increases blood glucose by activating hepatic glucagon receptors, stimulating glycogenolysis and gluconeogenesis.
Maintenance of fluid and electrolyte balance in patients unable to take oral intake,Correction of metabolic acidosis when bicarbonate is contraindicated or not available,Replacement of electrolytes in hypokalemia, hyponatremia, hypomagnesemia, and hypocalcemia
Treatment of severe hypoglycemia in pediatric and adult patients with diabetes mellitus aged 6 years and older
Intravenous infusion; rate and volume determined by individual patient requirements for fluid and electrolyte replacement. Typical adult dose: 500-1000 m L as a single infusion, administered at a rate of 5-10 m L/min.
Initial dose: 2 mg subcutaneously once daily for 2 weeks, then increase to 7 mg subcutaneously once daily. Dose may be increased to 12 mg subcutaneously once daily after 4 weeks if additional glycemic control is needed.
Not applicable as a single agent; components have variable half-lives (e.g., sodium and chloride distribute rapidly with an elimination half-life of 2-4 hours depending on renal function). In renal impairment, half-life may be prolonged.
Terminal elimination half-life is 5-7 hours in healthy adults; in hepatic impairment, half-life may be prolonged up to 12 hours, requiring dose adjustment.
Acetate and gluconate are metabolized in the liver via the tricarboxylic acid cycle to bicarbonate; electrolytes are distributed in body fluids and excreted renally.
Dasiglucagon is metabolized via proteolytic degradation into smaller peptides and amino acids; CYP enzymes are not involved.
Renal: >95% of administered electrolytes and water are excreted unchanged by the kidneys, primarily as urine. Biliary/fecal: <5% eliminated via feces, mainly unabsorbed components.
Primarily renal excretion of unchanged drug (approximately 70-80%) and minor hepatic metabolism with biliary/fecal elimination (10-15%).
Minimal to none: electrolytes like sodium, potassium, chloride, and bicarbonate are not protein-bound (<1%). Magnesium and calcium may have 30-50% binding to albumin, but overall negligible in solution.
Approximately 85% bound to albumin and alpha-1-acid glycoprotein.
Distributes primarily into extracellular fluid (ECF) with Vd approximately 0.2 L/kg for sodium and chloride; calcium and magnesium distribute into a larger volume (0.5-0.6 L/kg) due to intracellular uptake.
0.6-0.8 L/kg, indicating moderate tissue distribution with concentrations in tissues approximately 1.5 times plasma.
Intravenous: 100% (complete systemic availability). Not administered orally or by other routes for systemic effect.
Oral: 40-50% (due to first-pass metabolism); Intramuscular: 90-100%.
Contraindicated in patients with severe renal impairment (GFR < 30 m L/min) due to risk of hyperkalemia. For GFR 30-50 m L/min, reduce infusion rate by 50% and monitor serum potassium closely. No adjustment needed for GFR > 50 m L/min.
No dose adjustment required for mild to moderate renal impairment (e GFR ≥30 m L/min/1.73 m2). Not recommended for use in patients with end-stage renal disease (e GFR <15 m L/min/1.73 m2) due to lack of data.
Child-Pugh Class A: no adjustment. Class B: reduce infusion rate by 25% and monitor serum potassium. Class C: use with caution; consider alternative solutions due to risk of electrolyte imbalance.
No dose adjustment recommended for mild hepatic impairment (Child-Pugh class A). Not studied in moderate or severe hepatic impairment (Child-Pugh class B or C); use not recommended in these patients.
Weight-based dosing: 20-30 m L/kg as a single intravenous infusion, administered at a rate not exceeding 5 m L/kg/hour. Maximum total volume: 1000 m L. Adjust based on clinical status and serum electrolytes.
Not indicated for pediatric patients; safety and efficacy in patients <18 years have not been established.
Elderly patients may require reduced infusion rates (2-5 m L/min) due to decreased renal function and higher risk of fluid overload. Monitor serum potassium and renal function closely.
No specific dose adjustment required based on age alone. However, dosing should be cautious due to potential for decreased renal function or comorbidities; monitor renal function and volume status.
None
None.
Monitor serum electrolytes, fluid balance, and renal function regularly. Use with caution in patients with heart failure, renal impairment, or conditions predisposing to hypervolemia. Avoid rapid infusion; extravasation may cause tissue damage. Contains aluminum, which may accumulate in renal impairment.
Risk of serious hypersensitivity reactions including anaphylaxis,May cause nausea and vomiting,Risk of hypoglycemia if used in patients with insulinoma or glucagonoma,May increase blood pressure and heart rate
Hyperkalemia, hypernatremia, hypercalcemia, hypermagnesemia, severe metabolic alkalosis, severe renal failure with oliguria or anuria, and patients with a known hypersensitivity to any component.
Pheochromocytoma,Insulinoma,Known hypersensitivity to dasiglucagon or any excipients
No direct food interactions; however, patients should avoid high-potassium foods (e.g., bananas, oranges, tomatoes) if hyperkalemia is a concern. Monitor dietary sodium and fluid intake as per clinical status.
No specific food interactions. After recovery, administer oral carbohydrates to replenish liver glycogen and prevent recurrent hypoglycemia. Avoid alcohol as it may impair glucose recovery.
ISOLYTE E in plastic container is a balanced electrolyte solution without known teratogenic risk. No fetal harm has been documented in any trimester; however, excessive or rapid administration may cause maternal fluid and electrolyte disturbances that can indirectly affect the fetus. Use with caution in the setting of impaired uteroplacental perfusion.
Zegalogue (dasiglucagon) is a glucagon analog for severe hypoglycemia. No human pregnancy data; animal studies show no teratogenicity at exposures up to 40 times human dose. Risk cannot be excluded; use only if benefit outweighs risk. Fetal risks: potential for maternal hypoglycemia-induced fetal distress if not treated.
ISOLYTE E is compatible with breastfeeding. Electrolytes are normally present in breast milk; exogenous administration does not significantly alter infant exposure. M/P ratio not applicable as drug is not a xenobiotic.
No data on presence in human milk; dasiglucagon is a peptide likely degraded in GI tract. M/P ratio not determined. Caution in breastfeeding; consider risk of infant exposure vs benefit of treating maternal hypoglycemia.
No dose adjustment is required for pregnancy. However, pregnant patients may have increased plasma volume and altered renal function; infusion rates should be individualized based on clinical status and serum electrolyte monitoring. Rapid correction of electrolyte imbalances should be avoided to prevent fetal osmotic shifts.
No pharmacokinetic data in pregnancy; dosing adjustments not recommended. Use standard dose (0.6 mg) for severe hypoglycemia regardless of trimester.
ISOLYTE E is a balanced electrolyte solution with 5% dextrose, used for maintenance fluid therapy. Monitor serum potassium closely in renal impairment; contains 20 m Eq/L potassium. Caution in patients with hyperkalemia, renal failure, or metabolic alkalosis. Do not administer simultaneously with blood products due to risk of hemolysis. Observe for signs of fluid overload in patients with heart failure.
ZEGALOGUE (dasiglucagon) is a soluble glucagon analog indicated for severe hypoglycemia. It is stable in liquid form, avoiding reconstitution. Onset of action is 10-15 minutes, with blood glucose rise similar to native glucagon. Note that it can cause nausea and vomiting; if patient is unconscious, place in recovery position. Do not use if patient has pheochromocytoma, insulinoma, or known hypersensitivity. Store at room temperature.
This solution is used to replace fluids and electrolytes and provide calories. Tell your doctor if you have kidney problems, heart disease, or are on a low-potassium diet.
