Docusate
Mechanism :
Docusate is a stool softener. It is used to treat constipation due to hard stools, in painful anorectal conditions such as hemorrhoids. The effect of docusate may not necessarily be all due to its surfactant properties. Perfusion studies suggest that docusates inhibit fluid absorption or stimulate secretion in jejunum.
