ISOLYTE S PH 7.4 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 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 R provides electrolytes and water to maintain or restore fluid balance, with bicarbonate precursors (acetate, gluconate) to buffer metabolic acidosis.
Intravenous infusion; dose depends on fluid and electrolyte needs, typically 500-3000 mL/24 hours for adults.
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.

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 (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: 100% (electrolytes and buffer components are excreted unchanged by the kidneys; no biliary or fecal elimination).
Renal: >90% (electrolytes and water); Biliary/fecal: negligible (<5%)
