|Laxative||Dose||How supplied|| Cost|
|Lactulose||10 grams||1419 ml of 10gm/15ml solution|
(946 grams of lactulose)
(94.6 doses of 10 grams)
|Magnesium hydroxide||2.4-4.8 grams|
|Polyethylene glycol||17 grams||8.3 oz|
(238 grams of polyethylene glycol)
(14 doses of 17 grams)
|Sorbitol||13 grams||946 ml of 70% Solution|
(662 gms of sorbitol)
(50 doses of 13 grams)
Osmotic laxatives include saline-based laxatives and poorly absorbed sugar laxatives.
- Poorly absorbed sugar laxatives
Polyethylene glycol 3350 (PEG 3350) contains glycols with molecular masses over 3000 which are poorly absorbed. It is available with or without electrolytes. Polyethylene glycol is better than lactulose according to the Cochrane Collaboration. For adults, a randomized controlled trial found PEG [MiraLax or GlycoLax] 17 grams once per day better than tegaserod 6 mg twice per day. A randomized controlled trial found greater improvement from initial 2 sachets (26 grams) of PEG with electrolytes versus 2 sachets (20 grams) of lactulose with option to change to 1 or 3 sachets . 17 grams/day of PEG has been effective and safe in a randomized controlled trial for six months. Another randomized controlled trial found no difference between sorbitol and lactulose .
