What is the purpose of docusate in pharmacotherapy?

Docusate is primarily used as a stool softener, aiding individuals who may experience constipation or have difficulty passing stools. It works by decreasing the surface tension of the stool, allowing water and fats to penetrate more easily, which helps to soften it. This can be particularly beneficial for patients who may have conditions that prohibit straining during bowel movements, such as after surgery or for those with hemorrhoids.

In contrast, promoting gastric emptying relates to medications that stimulate the stomach to move contents more quickly into the small intestine, which does not align with docusate's function. Enhancing nutrient absorption pertains to agents designed to improve the uptake of vitamins and minerals, while reducing stomach acidity involves antacids or proton pump inhibitors designed to neutralize stomach acid, neither of which apply to docusate's role in treating constipation.
