5. Pharmacological properties
5.1 Pharmacodynamic properties

ATC code: A06A02 Laxatives, softeners, emollients

Docusate sodium is an anionic wetting agent, which acts as a faecal softener by lowering the surface tension and allowing penetration of accumulated hard dry faeces by water and salts.

Docusate Sodium also possesses stimulant activity.

5.2 Pharmacokinetic properties

Docusate sodium exerts its clinical effect in the gastrointestinal tract. There is some evidence that docusate sodium is absorbed and is excreted in the bile. There is also evidence that docusate sodium is capable of enhancing absorption of certain compounds administered concomitantly.
