POTASSIUM ACETATE vs POTASSIUM CHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Potassium acetate provides potassium ions, which are essential for maintaining intracellular ionic balance, nerve conduction, muscle contraction, and acid-base equilibrium. It acts as a potassium replenisher and can also be used to alkalinize urine by converting to bicarbonate.
Potassium is the major intracellular cation. It is essential for the maintenance of intracellular tonicity, transmission of nerve impulses, contraction of cardiac, skeletal, and smooth muscle, and maintenance of normal renal function. Potassium chloride dissociates to provide potassium ions and chloride ions. Potassium repletion corrects hypokalemia and associated disorders.
Intravenous, 10-20 mEq/h, maximum infusion rate 20 mEq/h, not to exceed 150 mEq/day.
Oral: 40-100 mEq/day in divided doses; IV: up to 10-20 mEq/hour via central line, max 40 mEq/hour with continuous monitoring; not to exceed 200 mEq/day.

Not applicable as potassium is not eliminated by first-order kinetics; plasma concentration reflects body stores and renal function.
Not applicable; potassium is an electrolyte regulated by homeostasis, not classic elimination half-life. Under normal renal function, serum half-life of administered potassium is approximately 2-4 hours due to rapid cellular uptake and renal excretion.
Primarily renal (>90%) as potassium ions; minimal biliary/fecal.
Primarily renal (90%) as potassium ion; minimal fecal (<10%) and sweat.
