Final answer:
The peri-colace/casanthranol and docusate sodium combination is specifically used for treating constipation by softening stools and stimulating bowel movements.
Step-by-step explanation:
The combination of peri-colace/casanthranol and docusate sodium is used for treating constipation. These medications work together to soften stools and stimulate bowel movements, making it easier to pass stools. This combination does not reduce stomach acid, relieve pain, or lower blood pressure. Instead, these actions are associated with other types of medications; for example, drugs that diminish HCl secretion are used in treating gastric ulcers, and medications to prevent inflammation or treat asthma and congenital heart diseases have different roles.
