Further study details as provided by Norgine:

Primary Outcome Measures:
  • Electrolyte profile in blood, urine and faeces, serum osmolality and effect on the renin/aldosterone ratio [ Time Frame: Ten days ]

Secondary Outcome Measures:
  • Amount of PEG 3350 in plasma, urine and faeces [ Time Frame: Ten days ]

Enrollment: 114
Study Start Date: January 2008
Primary Completion Date: August 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: PEG 3350 plus electrolytes
