Brief summary

Study evaluates the efficacy and tolerability of low volume preparations compared with conventional 4L polyethylene glycol prior to colonoscopy

Detailed description

To compare the efficacy and tolerance of standard polyethylene glycol to low volume sodium picosulphate/magnesium citrate and polyethylene glycol/ascorbic acid in a single or split dose regimen for colonoscopy bowel preparation in a head-to-head design.
