ISOLYTE S W/ DEXTROSE 5% IN PLASTIC CONTAINER vs PLASMA-LYTE 148 IN WATER IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Isolyte S with Dextrose 5% is an intravenous solution providing electrolytes and calories. Dextrose supplies glucose for cellular energy metabolism, while electrolytes (sodium, potassium, magnesium, chloride, acetate, gluconate) maintain acid-base balance and osmotic pressure. Acetate and gluconate are metabolized to bicarbonate, providing alkalinizing effect.
Plasma-Lyte 148 is an isotonic crystalloid solution that provides electrolyte replacement and volume expansion. It mimics plasma electrolyte composition, with acetate and gluconate as bicarbonate precursors that are metabolized to bicarbonate in the liver and kidneys, helping to maintain acid-base balance.
Intravenous infusion; dose determined by fluid and electrolyte requirements. Typical adult maintenance: 100-200 mL/h (2.4-4.8 L/day) depending on clinical status.
Intravenous infusion; dose determined by electrolyte and fluid requirements. Typical adult rate: 25-100 mL/hour.

Not applicable for the combination; individual components: dextrose has an elimination half-life of 15-20 minutes, electrolytes are not eliminated as a drug.
Not applicable; Plasma-Lyte 148 contains electrolytes and water that distribute according to body fluid compartments; infusion rate and renal function dictate elimination; clinical context: in normal renal function, excess fluids and electrolytes are cleared with a half-life of approximately 2-4 hours.
Renal excretion of electrolytes and water; dextrose is metabolized to CO2 and water, with <0.5% excreted unchanged in urine.
Renal: >90% of infused electrolytes and water are excreted unchanged in urine. Biliary/fecal excretion is negligible (<1%).
