Multiple Choice

Dr.Mark is asked to explain the mechanism of adsorbent drugs when they are used in the treatment of simple diarrhea.Which of the following statements should Mark choose?

• A) The adsorbents work in the intestine to form a complex with irritating substances such as bacteria, digestive enzymes, or toxins and carry them into the feces for elimination.
• B) The adsorbents remain in the intestine, soak up water, and expand. The water, which is retained, softens the stool, and the swelling action distends the rectum and initiates defecation.
• C) The adsorbents are a mixture of sodium and magnesium salts. These ions attract water, which causes a more liquid stool to be formed.
