- Contraindications & Blackbox Warnings
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.
