Which of the following is one of the eight routes of drug administration?

• A. Telepathy
• B. Astral projection
• C. Photonic transfer
• D. Oral

Answer: (D)

Understanding how a drug is given into the body is what this topic tests. The oral route means the medicine is swallowed and absorbed through the digestive system, usually in the small intestine. It’s one of the standard routes because it’s convenient, inexpensive, and easy for patients to use. However, how well it works can vary because absorption depends on factors like food in the stomach, pH, and liver metabolism after the drug is absorbed (first-pass effect), which can lower the amount that reaches the bloodstream. The other options aren’t real methods for delivering medicines in a clinical setting, so they don’t count as routes of drug administration. That makes oral the correct choice.
