ISOLYTE S PH 7.4 IN PLASTIC CONTAINER vs PLASMA-LYTE 56 AND DEXTROSE 5% IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Plasma-Lyte 56 and Dextrose 5% is a crystalloid solution that provides electrolytes and carbohydrates. Dextrose is metabolized to glucose, which is utilized for cellular energy production. The electrolytes (sodium, chloride, potassium, magnesium, and acetate) maintain or restore intravascular volume, acid-base balance, and osmotic gradients. Acetate is metabolized to bicarbonate, providing an alkalinizing effect.
Intravenous infusion; dose depends on fluid and electrolyte needs, typically 500-3000 mL/24 hours for adults.
Intravenous infusion; dose depends on fluid and electrolyte requirements. Typical adult dose: 500-1000 mL as a single infusion, rate up to 333 mL/hour. Maximum 3 L/24 hours.

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).
Not applicable; composition-dependent. Dextrose half-life ~2 hours. Electrolytes follow endogenous regulation; no terminal elimination half-life defined.
Renal: 100% (electrolytes and buffer components are excreted unchanged by the kidneys; no biliary or fecal elimination).
Renal 100% (electrolytes and dextrose metabolized to CO2 and water; excess water and electrolytes excreted unchanged in urine).
