ISOLYTE M IN DEXTROSE 5% 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 M in Dextrose 5% is a crystalloid solution that provides water, electrolytes, and calories. Dextrose is metabolized to carbon dioxide and water, yielding energy. The electrolytes (sodium, potassium, magnesium, chloride, acetate, and gluconate) maintain or restore intravascular volume and acid-base balance. Acetate and gluconate are bicarbonate precursors, metabolized in the liver and peripheral tissues to generate bicarbonate, thus correcting metabolic acidosis.
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 determined by fluid and electrolyte requirements; typical adult rate 100-200 mL/hour.
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.

No true terminal half-life; infused components (water and electrolytes) follow endogenous kinetics. Dextrose half-life approx. 1-2 hours, electrolytes distribute and are excreted based on renal function.
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)
Primarily renal; >90% of infused water and electrolytes are excreted unchanged via kidneys with minimal biliary or fecal elimination.
Renal: >90% (electrolytes and water); Biliary/fecal: negligible (<5%)
