Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Potassium is the principal intracellular cation and is essential for maintaining cellular membrane potential, nerve impulse transmission, and muscle contraction. Dextrose provides calories and may prevent ketosis.
Sodium succinate is a salt of succinic acid, which serves as an intermediate in the tricarboxylic acid (TCA) cycle. It acts as a metabolic supplement, enhancing cellular respiration and energy production by providing substrate for the TCA cycle. It also exhibits antioxidant properties by scavenging free radicals.
Intravenous; typical adult dose is 10-20 mEq/hour, not exceeding 40 mEq/hour or 150 mEq/day, with continuous cardiac monitoring and serum potassium monitoring.
No established standard dosing for sodium succinate as a therapeutic agent; it is used as a pharmaceutical excipient or buffering agent in intravenous formulations. For buffering purposes, typical concentrations range from 0.5% to 2% in injection solutions, administered intravenously at rates adjusted per clinical need.

The elimination half-life of potassium is not applicable in the traditional sense because potassium is an endogenous ion under tight homeostatic control. After intravenous infusion of a potassium load, the plasma concentration declines with a distribution phase of about 1-2 hours, followed by a slower elimination phase reflecting cellular uptake and renal excretion, with a terminal half-life of approximately 6-8 hours in patients with normal renal function.
5-10 minutes; rapid elimination limits systemic effects.
Renal: >90% of potassium intake is excreted by the kidneys, primarily via distal tubular secretion; fecal: <10%; minor sweat losses. In this formulation (KCl 0.22% in D5W), the potassium content is 2 mEq per 100 mL (approximately 20 mEq/L).
Renal excretion of unchanged drug; less than 5% biliary/fecal.
