Prevent Adverse Drug Events TodayTap into our Clinical API for life-saving information on contraindications & blackbox warnings, population restrictions, harmful risks, & more.Avoid life-threatening adverse drug events with our Clinical API- Pharmacodynamics
Sodium phosphate inceases fecal water content to increase mobility through the large intestine 1.
- Mechanism of action
Sodium phosphate is thought to work by increasing the amount of solute present in the intestinal lumen thereby creating an osmotic gradient which draws water into the lumen 1.
- Absorption
Tmax for phosphate absorption with orally administered liquid sodium phosphate is 1-3h 3.

Intamuscular LD50 of 250mg/kg and oral LD50 of 8290 mg/kg reported in rats 7. Phosphate toxicity is likely due to the disturbance of other electrolytes when phosphate levels are high, producing symptoms including tetany, dehydration, hypotension, tachycardia, hyperpyrexia, cardiac arrest and coma 4. Risk of raising phosphate levels through use of sodium phosphate appears to be higher in smaller patients 3.

- Sodium-phosphate symporter which preferentially transports the monovalent form of phosphate with a stoichiometry of two sodium ions per phosphate ion (PubMed:11009570, PubMed:16790504, PubMed:17494632, PubMed:19726692, PubMed:7929240, PubMed:8041748). May play a role in extracellular matrix and cartilage calcification as well as in vascular calcification (PubMed:11009570). Essential for cell proliferation but this function is independent of its phosphate transporter activity (PubMed:19726692)

Plays a critical role in the determination of bone quality and strength by providing phosphate for bone mineralization (By similarity). Required to maintain normal cerebrospinal fluid phosphate levels (By similarity). Mediates phosphate-induced calcification of vascular smooth muscle cells (VCMCs) and can functionally compensate for loss of SLC20A1 in VCMCs (By similarity)
