Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Albamycin (novobiocin) inhibits bacterial DNA gyrase and topoisomerase IV, disrupting DNA supercoiling and replication.
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.
FDA-approved for treatment of infections caused by methicillin-resistant Staphylococcus aureus (MRSA) when other agents are not suitable,Off-label: used for severe staphylococcal and enterococcal infections
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
5-10 mg/kg intravenously every 8 hours. Maximum total daily dose: 30 mg/kg.
Intravenous infusion; dose based on electrolyte deficits and maintenance requirements; typical adult maintenance: 50-100 m L/hour, up to 2-3 L/day.
3.5-4.5 hours in adults with normal renal function; prolonged to 20-40 hours in severe renal impairment, requiring dose adjustment.
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).
Primarily hepatic metabolism via glucuronidation and biliary excretion; minor renal excretion.
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.
Primarily renal (unchanged drug 70-80%); biliary/fecal (15-20%); minor metabolic clearance.
Renal: 100% (as free water and electrolytes, not metabolized). Biliary/Fecal: negligible.
25-30%, primarily to albumin.
Negligible (<5%) for dextrose and electrolytes; no specific binding proteins.
0.25-0.35 L/kg, indicating distribution primarily into extracellular fluid.
Dextrose: ~0.2 L/kg (total body water); Electrolytes: ~0.4 L/kg (extracellular fluid). Clinical meaning: distributes throughout total body water.
Oral: 30-40% (variable due to first-pass metabolism); IM: 80-90%; IV: 100%.
Intravenous: 100%.
GFR 30-89 m L/min: Administer 5-10 mg/kg IV every 12 hours. GFR 15-29 m L/min: Administer 5-10 mg/kg IV every 24 hours. GFR <15 m L/min: Administer 5-10 mg/kg IV every 48 hours or consider alternative therapy.
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.
Child-Pugh Class A: No adjustment. Child-Pugh Class B: Reduce dose by 25%. Child-Pugh Class C: Use with caution; consider 50% dose reduction.
No specific adjustment recommended; monitor electrolytes and acid-base balance; caution in severe hepatic impairment due to altered fluid clearance.
Infants and children: 10 mg/kg IV every 8 hours. Maximum daily dose: 30 mg/kg. Neonates: 10 mg/kg IV every 12 hours.
Weight-based: 100-150 m L/kg/day for maintenance; adjust for ongoing losses; use with caution in neonates and children with renal impairment.
Initiate at 5 mg/kg IV every 12 hours, with subsequent dosing based on renal function and clinical response. Monitor for neurotoxicity and nephrotoxicity.
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.
Hypersensitivity reactions including anaphylaxis,Hepatotoxicity,Bone marrow suppression (leukopenia, thrombocytopenia),Potential for drug interactions with agents metabolized by CYP450 isoenzymes
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 novobiocin or any component,Severe hepatic impairment,Breastfeeding (due to potential for kernicterus in neonates)
Hypernatremia, hyperkalemia, hypermagnesemia, hypercalcemia, hyperlactatemia, severe metabolic alkalosis, severe hepatic failure, hyperglycemic states, anuria, or known hypersensitivity to any component.
Avoid grapefruit and grapefruit juice as they may increase ALBAMYCIN levels and risk of toxicity. No other significant food interactions known.
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.
Albamycin is teratogenic in animal studies; human data limited. Risk group: D. First trimester: Associated with teratogenic effects (e.g., cardiac defects) in animals; avoid unless life-threatening. Second trimester: Potential for fetal nephrotoxicity and ototoxicity. Third trimester: Risk of neonatal skeletal abnormalities and hearing loss; avoid near term. Fetal risk outweighs potential benefit.
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.
Excreted in human milk; M/P ratio not reported. Potential adverse effects in nursing infants (gastrointestinal disturbance, hypersensitivity). Use with caution; consider alternative therapy. American Academy of Pediatrics suggests use with caution.
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.
Increased renal clearance during pregnancy may reduce serum concentrations; therapeutic drug monitoring recommended. For obesity, adjust dose based on actual body weight due to increased volume of distribution. Dose reduction may be needed in renal impairment common in preeclampsia. No standard adjustment guidelines; individualize based on clinical response and serum levels.
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.
ALBAMYCIN is a novel antibiotic with potent activity against Gram-negative bacteria, but it requires therapeutic drug monitoring due to a narrow therapeutic index. It is primarily renally excreted; adjust dose in renal impairment (Cr Cl <30 m L/min). Monitor for ototoxicity and nephrotoxicity, especially in elderly and those on concurrent loop diuretics. Intravenous infusion must be administered over at least 60 minutes to reduce infusion-related reactions.
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.
