Bisacodyl in Rectal form is an example of which route of administration?

• A. Sublingual
• B. Rectal
• C. Oral
• D. Topical

Answer: (B)

The main concept here is route of administration. When a medication is described as rectal, it is given through the rectum. Bisacodyl in Rectal form is meant to be inserted into the rectum and acts locally in the lower bowel to stimulate a bowel movement. This differs from sublingual (under the tongue), oral (swallowed), or topical (applied to skin or mucous membranes) routes, which are not how a rectal laxative is delivered. The rectal route is used when a patient can’t take meds by mouth or when a local effect in the lower colon is desired, which fits how this drug works.
