ISOLYTE P W/ DEXTROSE 5% IN PLASTIC CONTAINER vs PLASMA-LYTE R 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 R provides electrolytes and water to maintain or restore fluid balance, with bicarbonate precursors (acetate, gluconate) to buffer metabolic acidosis.
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 at a rate of 25-50 mL/kg body weight per 24 hours, adjusted for fluid and electrolyte needs. Typical adult maintenance dose: 1-2 L/day.

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 R components are endogenous electrolytes and water; administered crystalloid redistributes rapidly; half-life of approximately 20-30 minutes for volume expansion due to renal excretion and redistribution into interstitial space)
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% (electrolytes and water); Biliary/fecal: negligible (<5%)
