Quizplus · Accepted Answer

Oral route requires the drug to pass through the digestive system, where the drug is broken down and absorbed slowly into the bloodstream, making it the slowest way for a drug to reach the cells of the body. The other routes of administration provide a more direct and faster route for drug delivery. Rectal and inhalation routes bypass the digestive system and parenteral (intravenous, intramuscular, subcutaneous) routes directly introduce the drug into the bloodstream.
