Colon cleansing before colonoscopy: does oral sodium phosphate solution still make sense?

Area of Science:

• Gastroenterology
• Nephrology
• Pharmacology

Background:

• Oral sodium phosphate (NaP) solution was a common bowel preparation for colonoscopy.
• Concerns regarding renal toxicity have led to market withdrawal in the United States.
• NaP remains available over-the-counter in Canada for colonoscopy preparation.

Purpose of the Study:

• To review current data on the renal toxicity of oral NaP.
• To compare the efficacy and tolerability of oral NaP with alternative bowel preparations.
• To provide recommendations for the safe use of oral NaP where it remains available.

Main Methods:

• Systematic review of recent scientific literature.
• Analysis of data on renal toxicity, efficacy, and tolerability.
• Comparative assessment against other colonoscopy bowel preparations.

Main Results:

• Oral NaP carries risks of renal toxicity.
• Effective and well-tolerated alternatives to NaP solution are available.
• The use of NaP for colonoscopy preparation should be restricted.

Conclusions:

• Given the availability of safer alternatives, oral NaP solution use for colonoscopy preparation in Canada should be limited.
• Patients considered for oral NaP must be carefully assessed for eligibility.
• Adherence to safety recommendations is crucial for minimizing risks associated with oral NaP.
