The brand name "Duphalac" is associated with which type of medication?

Duphalac is the brand name for a medication containing lactulose, which is classified as a laxative. It is primarily used to treat constipation by drawing water into the bowel, thereby softening the stool and promoting bowel movements. This action helps alleviate difficulties in passing stools and can be particularly beneficial for individuals suffering from chronic constipation or those who are on certain medications that can cause constipation as a side effect.

Conversely, the other categories mentioned in the question serve different therapeutic purposes. Narcotic analgesics are used for pain management, anticoagulants are blood thinners used to prevent blood clots, and otic agents are designed for conditions affecting the ears. Understanding the specific uses and classifications of medications is vital for safe medication administration and patient care.
