ISOLYTE P 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 P with 5% Dextrose provides electrolyte replacement and caloric supplementation. Dextrose is metabolized to carbon dioxide and water, yielding energy. Electrolytes are essential for maintaining osmotic balance, acid-base equilibrium, and normal 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. Adult dose: 1000-2000 mL over 24 hours, adjusted based on fluid and electrolyte needs. Typical rate: 125-150 mL/hour.
Intravenous infusion; dose determined by electrolyte and fluid requirements. Typical adult rate: 25-100 mL/hour.

Dextrose: rapid clearance, half-life ~1.5-2 hours in normoglycemic patients; prolonged in renal impairment or diabetes. Electrolytes follow homeostatic regulation with no defined terminal half-life.
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 free water and electrolytes; dextrose is metabolized to CO2 and water, with negligible biliary or fecal elimination. Approximately 50-70% of infused water is excreted renally within 24 hours, adjusted by ADH and renal function.
Renal: >90% of infused electrolytes and water are excreted unchanged in urine. Biliary/fecal excretion is negligible (<1%).
