Pharmacology

Indication

Dipotassium phosphate is used in imitation dairy creamers, dry powder beverages, mineral supplements, and starter cultures as an additive. It is used in non-dairy creamers to prevent coagulation. Dipotassium phosphate is also used to make buffer solutions and it is used in the production of trypticase soy agar which is used to make agar plates for culturing bacteria.

Pharmacodynamics

Phosphate is a major intracellular anion which participates in providing energy for metabolism of substances and contributes to important metabolic and enzymatic reactions in almost all organs and tissues. Phosphate exerts a modifying influence on calcium concentrations, a buffering effect on acid-base equilibrium, and has a major role in the renal excretion of hydrogen ions.

Mechanism of action

Once phosphate gains access to the body fluids and tissues, it exerts little pharmacological effect. If the ion is introduced into the intestine, the absorbed phosphate is rapidly excreted. If large amounts are given by this route, much of it may escape absorption. Because this property leads to a cathartic action, phosphate salts are employed as mild laxatives.

Absorption

Potassium salts are well absorbed from gastro intestinal tract. Net phosphorus absorption may occur in the small intestine in some species but is primarily a function of the colon in horses.

Volume of distribution

Distribution is largely intracellular, but it is the intravascular concentration that is primarily responsible for toxicity.

Protein binding

Phosphate is minimally protein bound, and highly concentrated in cells (intracellular concentrations are 100-fold higher than serum concentrations). Concentrations of phosphate in plasma are higher in children than in adults.

Metabolism

Phosphate is a major intracellular anion which participates in providing energy for metabolism of substances and contributes to important metabolic and enzymatic reactions in almost all organs and tissues.

Route of elimination

Potassium is excreted primarily by kidney.

Half-life

In healthy children with phosphate overdose, half-life was 4.8 to 10.6 hours, and was prolonged to 17 hours in a child with renal insufficiency.

Clearance

Phosphates are rapidly cleared by dialysis.
