Phosphate is a major intracellular anion that participates in providing energy for metabolism of substrates 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.
How the body processes this drug — absorption, distribution, metabolism, and elimination
Potassium is excreted mainly by the kidneys. Small amounts of potassium may be excreted via the skin and intestinal tract, but most of the potassium excreted into the intestine is later reabsorbed.
