Which of the following is NOT a dosage form of medication?

The correct answer is D. Inhalers are indeed a dosage form of medication. They are devices that deliver medication directly into the lungs, providing an effective method for treating respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). Inhalers can come in various types, including metered-dose inhalers and dry powder inhalers, and are categorized as a specific dosage form due to their unique delivery method.

All the other options listed—tablets, patches, and creams—are recognized dosage forms as well. Tablets are solid dosage forms that dissolve in the gastrointestinal tract, patches are transdermal delivery systems that release medication through the skin over time, and creams are semi-solid emulsions used for topical application.

In summary, inhalers are classified as a dosage form, and understanding the various ways medications can be administered is crucial in the field of pharmacy practice.
