Pharmacology

Docusate Sodium is the sodium salt of docusate, a dioctyl salt and an emollient laxative with stool-softening activity. Docusate decreases surface tension and emulsification of fecal matter and allows water to penetrate and mix with stool. As a result, it softens the stool.

How it is made

Prepd by reaction of appropriate alcohol with maleic anhydride followed by addition of sodium bisulfite: jaeger, us patents 2.028,091, 2,176,423 (1936, 1939, both to american cyanamid).
