Pharmacological Index

Stool Softener


Use

Stool softener in patients who should avoid straining during defecation and constipation associated with hard, dry stools; prophylaxis for straining (Valsalva) following myocardial infarction. A safe agent to be used in elderly; some evidence that doses <200 mg are ineffective; stool softeners are unnecessary if stool is well hydrated or "mushy" and soft; shown to be ineffective used long-term.


Pregnancy Risk Factor

C

Mechanism of Action

Reduces surface tension of the oil-water interface of the stool resulting in enhanced incorporation of water and fat allowing for stool softening
