ISOLYTE P IN DEXTROSE 5% IN PLASTIC CONTAINER vs PLASMA-LYTE 148 IN WATER IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ISOLYTE P in Dextrose 5% provides electrolytes (sodium, potassium, magnesium, chloride, acetate, phosphate) and dextrose to maintain fluid and electrolyte balance, restore intravascular volume, and supply calories. Dextrose is metabolized to carbon dioxide and water, providing energy. Acetate acts as an alkalinizing agent, metabolized to bicarbonate in the liver.
Plasma-Lyte 148 is an isotonic crystalloid solution that provides electrolyte replacement and volume expansion. It mimics plasma electrolyte composition, with acetate and gluconate as bicarbonate precursors that are metabolized to bicarbonate in the liver and kidneys, helping to maintain acid-base balance.
Intravenous infusion; dose determined by fluid, electrolyte, and caloric requirements. Typical adult rate: 100-200 mL/hr; maximum infusion rate 10 mL/min.
Intravenous infusion; dose determined by electrolyte and fluid requirements. Typical adult rate: 25-100 mL/hour.

Not applicable as a combination product. Dextrose: 1-2 hours (metabolic clearance). Electrolytes: distribution half-life ~15-30 minutes, elimination depends on renal function; in normal renal function, complete clearance within 2-4 hours.
Not applicable; Plasma-Lyte 148 contains electrolytes and water that distribute according to body fluid compartments; infusion rate and renal function dictate elimination; clinical context: in normal renal function, excess fluids and electrolytes are cleared with a half-life of approximately 2-4 hours.
Renal: 100% (electrolytes and dextrose metabolites, primarily water and CO2). No biliary or fecal elimination of significant amount.
Renal: >90% of infused electrolytes and water are excreted unchanged in urine. Biliary/fecal excretion is negligible (<1%).
