Serial Monitoring of the Physiological Effects of the Standard Pico-Salax® Regimen for Colon Cleansing in Healthy Volunteers

Abstract

BACKGROUND: Sodium picosulfate/magnesium oxide/citric acid (Pico-Salax, Ferring Inc, Canada) is used widely in Canada and other countries for colon cleansing before colonoscopy. It is a low-volume osmotic/stimulant agent with the potential to deplete intravascular volume and alter electrolyte balance, yet there are little data regarding its effects on these clinically important end points.
