To compare the efficacy and safety of polyethylene glycol (PEG) 3350 plus electrolytes (PEG+E; Movicol((R))) with that of ispaghula husk (psyllium; Konsyl((R))) in the treatment of constipation.Male or female adults with chronic functional constipation.This was a randomised, controlled, open-label, parallel-group trial. Study treatment was either PEG+E 13.8g/sachet dissolved in water twice daily or ispaghula husk 3.5g/sachet dissolved in water twice daily for a period of 2 weeks. Assessments were at baseline and after 1 and 2 weeks' therapy and by patient daily diary card. The primary outcome measures were weekly defaecation rate, stool consistency according to the Bristol Stool Form scale, time to first defaecation, and overall efficacy, which combined defaecation rate, stool consistency and difficulty on defaecation. Adverse effects were recorded and laboratory assessments were performed before and at the end of the treatment period.Sixty-three patients were randomised to each treatment group. Treatment was highly effective in 50/63 patients in the PEG+E group compared with 26/63 in the ispaghula husk group, and the overall efficacy rates were 92
