Which term specifically describes taking a substance by mouth and swallowing into the stomach?

• A. Oral administration
• B. Intravenous administration
• C. Subcutaneous administration
• D. Intramuscular administration

Answer: (A)

Oral administration is the route where a substance is taken by mouth and swallowed into the stomach, allowing it to pass through the digestive tract to be absorbed, usually in the small intestine. This distinguishes it from injection routes like intravenous, subcutaneous, or intramuscular, which deliver substances directly into the bloodstream or tissues and bypass the digestive system. Oral administration includes tablets, capsules, and liquids, and its effectiveness can be influenced by factors such as stomach pH, gastric emptying, and first-pass metabolism in the liver before the drug reaches systemic circulation.
