ISOLYTE R 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 R with Dextrose 5% is an intravenous solution providing electrolytes (sodium, potassium, magnesium, calcium, chloride, acetate, gluconate) and dextrose. Dextrose provides calories and may prevent ketosis; electrolytes maintain or restore acid-base balance and provide essential ions for cellular function.
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 at a rate of 125-200 mL/hour (3 mL/kg/hour) for fluid and electrolyte maintenance, adjusted based on clinical status, serum electrolytes, and glucose monitoring.
Intravenous infusion; dose determined by electrolyte and fluid requirements. Typical adult rate: 25-100 mL/hour.

Not applicable as a composite solution; glucose half-life ~1.5-2 h in normal individuals, extended in renal impairment; electrolytes follow body homeostasis.
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: ~100% as water, electrolytes, and glucose; no biliary or fecal elimination of active drug components.
Renal: >90% of infused electrolytes and water are excreted unchanged in urine. Biliary/fecal excretion is negligible (<1%).
