For adults, a randomized controlled trial found PEG [MiraLax or GlycoLax] 17 grams once per day better than tegaserod 6 mg twice per day.[2] A randomized controlled trial found greater improvement from 2 sachets (26 grams) of PEG versus or 2 sachets (20 grams) of lactulose [3]. 17 grams/day of PEG has been effective and safe in a randomized controlled trial for six months.[4] Another randomized controlled trial found no difference between sorbitol and lactulose [5].

For children, PEG was found to be more effective than lactulose.[6]
