ISOLYTE S PH 7.4 IN PLASTIC CONTAINER vs PLASMA-LYTE 56 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 is an isotonic crystalloid solution that provides electrolytes and water to maintain or restore intravascular volume and electrolyte balance. It expands extracellular fluid volume and improves circulation by increasing plasma volume. The solution's electrolyte composition mimics plasma, helping to correct electrolyte deficits and acid-base disturbances.
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 needs; typical adult rate: 100-200 mL/hour.

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 as a fixed value; infused electrolytes distribute and are eliminated according to individual ion kinetics (e.g., sodium t½ ~30 min, chloride t½ ~1–2 h) with rapid redistribution.
Renal: 100% (electrolytes and buffer components are excreted unchanged by the kidneys; no biliary or fecal elimination).
Primarily renal; >90% of infused electrolytes are excreted unchanged in urine; fecal elimination negligible (<5%).
