However reports surfaced on renal damage for some using the oral phosphates and accordingly the FDA issued a warning with particular concern expressed regarding those patients who were using certain blood pressure pills, namely the ACEi and the ARBs.
Now we have a recent retrospective report from the Scott and White Clinic in Texas which tends to reinforce the concern. The authors conclude:
Oral sodium phosphate solution preparation is associated with decline in GFR in elderly patients with creatinine levels in the normal range. Its routine use for elective and screening procedures should be discouraged in the elderly population.
I agree- the PEG solutions are safer.
