ISOLYTE P IN DEXTROSE 5% IN PLASTIC CONTAINER vs ISOLYTE S 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.
Isolyte S is an electrolyte and fluid replenisher. It provides water and essential electrolytes (sodium, potassium, magnesium, chloride, acetate, gluconate) to restore and maintain extracellular fluid volume and electrolyte balance. Acetate and gluconate are metabolized to bicarbonate, serving as bicarbonate precursors to help correct metabolic acidosis.
Intravenous infusion; dose determined by fluid, electrolyte, and caloric requirements. Typical adult rate: 100-200 mL/hr; maximum infusion rate 10 mL/min.
Intravenous administration, typical adult dose is 500-1000 mL per hour, adjusted based on clinical status and electrolyte needs.

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.
The terminal elimination half-life for the individual electrolytes varies: Sodium has a half-life of approximately 2-4 hours depending on hydration and renal function; potassium has a half-life of 5-7 hours in normal renal function; magnesium has a half-life of 24-72 hours; calcium has a half-life of 3-6 hours. Clinically, the half-life is prolonged in renal impairment, necessitating dose adjustment.
Renal: 100% (electrolytes and dextrose metabolites, primarily water and CO2). No biliary or fecal elimination of significant amount.
The electrolytes in ISOLYTE S are primarily excreted via renal elimination. Sodium and chloride are almost entirely excreted by the kidneys, with minimal biliary or fecal elimination (<2%). Potassium is predominantly excreted renally (90%), with approximately 10% eliminated via feces. Magnesium and calcium are mainly excreted in urine (70-80% for magnesium, 20-30% for calcium) with some biliary/fecal excretion. Acetate and gluconate are metabolized to bicarbonate and excreted renally.
