Diluted phosphoric acid national formulary: it has ... been employed in lead poisoning and in other conditions in which it is desired to administer large amount of phosphate and at /the/ same time produce mild acidosis. It has been given in dose of 60 mL daily (5 mL/hr) under carefully controlled conditions.

Phosphoric acid is used in dentistry and orthodontics as an etching solution, to clean and roughen the surfaces of teeth where dental appliances or fillings will be placed.
Transport of phosphate from the gut lumen is an active, energy-dependent process that is modified by several factors. ... Vitamin D stimulates phosphate absorption, an effect reported to precede its action on calcium ion transport.
Dental Materials
Materials used in the production of dental bases, restorations, impressions, prostheses, etc. (See all compounds classified as Dental Materials.)
Absorption
Ortho phosphate is absorbed from, and to a limited extent secreted into, the gastrointestinal tract.
Route of Elimination
In adults, about two thirds of the ingested phosphate is absorbed, and that which is absorbed is almost entirely excreted into the urine.
Volume of Distribution
Absorbed phosphoric acid is distributed widely in the body as phosphate. Increased serum phosphate concentrations have been reported rarely after phosphoric acid ingestion
Clearance
Absorbed phosphate is filtered at the glomerulus and partially reabsorbed, with phosphate clearance 80 per cent of creatinine clearance.
The hygroscopic growth of phosphoric acid aerosol (diameter change > 0.5 micrometers) within the human tracheobronchial tree is modeled to investigate changes in deposition characteristics when compared to nonhygroscopic aerosols of identical preinspired size. Phosphoric acid particles are assumed to grow in a stepwise fashion to 99% relative humidity within conducting airways of the lung, having initially reached equilibrium at 90% relative humidity (T= 37 degrees) in the trachea. Deposition efficiencies for growth and no growth are calculated from theoretical equations for inertial impaction, sedimentation, and diffusion. The results show that neglecting the growth of an inhaled phosphoric acid aerosol may result in underestimation of the total deliverable dose by a factor of as much as 600-700%. Significant differences in regional deposition sites for hygroscopic or nonhygroscopic aerosols are predicted. Increased deposition efficiencies imply that measured physical properties (respirable fraction, aerodynamic diameter) of aerosols alone are not sufficient to assess deposition characteristics within the lung; hygroscopic growth must also be considered.

/Ortho/ phosphate is absorbed from, and to a limited extent secreted into, the gastrointestinal tract. Transport of phosphate from the gut lumen is an active, energy-dependent process that is modified by several factors. ... Vitamin D stimulates phosphate absorption, an effect reported to precede its action on calcium ion transport. In adults, about two thirds of the ingested phosphate is absorbed, and that which is absorbed is almost entirely excreted into the urine. In growing children, phosphate balance is positive. Concentrations of phosphate in plasma are higher in children than in adults. This "hyperphosphatemia" decreases the affinity of hemoglobin for oxygen and is hypothesized to explain the physiological "anemia" of childhood. /Phosphates/

The level of inorganic phosphate in the blood is stabilized by exchange with the mineral deposit in the skeleton through the action of parathyroid hormone. This hormone inhibits tubular reabsorption of phosphates by the kidney and brings about demineralization of bone tissue through the action of osteoclasts. The amount of parathyroid hormone that enters the circulation is probably regulated by the calcium level of the blood.

In infants with normal renal function the serum half-life of phosphate following single oral or rectal overdose is 5-11 hours
Phosphate supplementation of the diet of rodents has been shown to lead to reduction in the incidence of dental caries and different phosphates have different powers in reducing the cariogenic potential of the carbohydrates in a diet. Phosphate supplements seem to exert their cariostatic effect on the tooth surface either directly during eating or by excretion in the saliva.
