Rationale: Rectal drugs usually supply systemic effects because of a high rate of absorption via the colon. A lesser amount of rectal drugs is intended to provide localized effects, such as suppositories that treat hemorrhoids. The other choices are incorrect because the use of rectal drugs for antitussive and antipyretic effects is not common.
