Which term refers to the method of delivering medication into the body?

The term that refers to the method of delivering medication into the body is "Administration Route." This concept is fundamental in pharmacology and healthcare, as the route of administration can greatly influence the effectiveness and onset of a medication. Different routes, such as oral, intravenous, intramuscular, subcutaneous, and inhalation, determine how quickly and efficiently a drug enters the bloodstream and reaches its site of action.

Understanding the administration route is essential for medication aides and healthcare professionals, as it impacts everything from dosage calculations to patient education. For instance, some medications may need to be delivered via specific routes to avoid degradation in the digestive system or to ensure rapid action in emergency situations.

The other terms, such as absorption, refer to the process through which the body takes up the drug after it has been administered, while active refusal is not related to medication delivery but instead concerns a patient's choice regarding their treatment. Administration frequency, on the other hand, pertains to how often medication is given rather than how it is delivered. Thus, the term "Administration Route" specifically encapsulates the method of delivering medication into the body, making it the correct answer.
