Which of the following are the three main routes of medication administration?

The three main routes of medication administration indeed include oral, intravenous, and intramuscular methods.

The oral route is one of the most common and involves administering medication through the mouth, which is convenient and non-invasive. It allows for a wide variety of medications to be absorbed gradually in the digestive tract.

Intravenous administration delivers medication directly into the bloodstream, providing immediate effects and precise control over drug levels. This method is often used in emergency situations or when a rapid response is needed.

Intramuscular injections involve introducing medication deep into muscular tissue, allowing for faster absorption than oral administration, while still being more gradual than intravenous delivery. This route is particularly useful for vaccines and certain medications that need to be absorbed more quickly than what oral administration can provide.

Together, these three routes encompass a range of delivery mechanisms that are essential in clinical practice for effectively administering medications tailored to patient needs.
