Which of the following is not considered a dosage form?

The correct answer is the choice that identifies "oral" as it is not considered a dosage form, but rather a route of administration. Dosage forms refer to the actual physical forms in which medications are prepared for administration to patients, ensuring the medication is delivered effectively.

Suspensions, ointments, and liquids are all specific formulations designed to deliver a drug to the body. A suspension is a liquid mixture containing solid particles that are not dissolved; it must be shaken before use. An ointment is a semisolid preparation usually applied to the skin for local effect, serving as a vehicle for the active ingredient. Liquids, including solutions and suspensions, are forms of dosage that can be administered orally, intravenously, or through other routes.

In contrast, "oral" describes how the medication is taken—through the mouth—rather than the form of the medication itself. It encompasses various dosage forms such as tablets, capsules, liquids, and suspensions designed for oral use. This distinction clarifies why "oral" does not belong in the category of dosage forms. Understanding these differences is crucial for pharmacy technicians as they prepare medications and counsel patients on their proper use.
