ISOLYTE P W/ DEXTROSE 5% IN PLASTIC CONTAINER vs ISOLYTE S PH 7.4 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.
Isolyte S pH 7.4 is an isotonic crystalloid solution that expands intravascular volume and replaces extracellular fluid losses. It provides electrolytes (sodium, chloride, potassium, magnesium, acetate, gluconate) to maintain acid-base balance and osmotic pressure. Acetate and gluconate are metabolized to bicarbonate, providing alkalinizing effect.
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 depends on fluid and electrolyte needs, typically 500-3000 mL/24 hours for adults.

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 (components are endogenous substances; half-life reflects renal clearance and volume status, typically 2-4 hours for sodium and chloride in euvolemic patients).
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: 100% (electrolytes and buffer components are excreted unchanged by the kidneys; no biliary or fecal elimination).
