PLASMA-LYTE 56 AND DEXTROSE 5% IN PLASTIC CONTAINER vs PLASMA-LYTE A IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Maintenance and restoration of fluid and electrolyte balance; provides isotonic crystalloid solution with sodium, potassium, magnesium, chloride, and acetate/bicarbonate precursors to buffer acidity.
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.
Intravenous infusion; adult dose is based on electrolyte and fluid requirements, typically 500-1000 mL/hour initially, then adjusted; maximum rate 30 mL/kg/hour.

Not applicable; composition-dependent. Dextrose half-life ~2 hours. Electrolytes follow endogenous regulation; no terminal elimination half-life defined.
Not applicable as a single half-life; electrolytes have distribution and elimination phases governed by body stores and renal function. For water, elimination half-life is ~2-4 hours in euvolemic individuals with normal GFR. Clinically, infused volume distributes within ~30 minutes and is renally cleared over several hours.
Renal 100% (electrolytes and dextrose metabolized to CO2 and water; excess water and electrolytes excreted unchanged in urine).
Electrolytes and water are primarily excreted renally: sodium (90-95% filtered, reabsorbed), chloride (follows sodium), potassium (80-90% renal, 10% fecal), magnesium (30-50% reabsorbed, remainder excreted), acetate (metabolized to bicarbonate, ultimately renal). Fluid volume is regulated by renal mechanisms (ADH, aldosterone). Essentially 100% of administered volume and electrolytes are eliminated via kidneys under normal physiology.
