Which of the following is a characteristic of tablets?

The characteristic that aligns with tablets is that they consist of compressed powdered ingredients. Tablets are created by compressing a mixture of active pharmaceutical ingredients and excipients (inactive substances that serve as the vehicle for the drug). This method of preparation enables the medication to maintain its shape, stability, and dosage accuracy. Tablets are versatile forms of medication that can be produced in various strengths and formulations, making them suitable for many therapeutic purposes.

In contrast, the other options do not accurately represent the nature of tablets. While some tablets may be flavored, not all are; therefore, they are not always flavored for better taste. Tablets are also not administered through injection; such a method is typically reserved for liquid medications or some formulations like injectables. Lastly, tablets do not require refrigeration; instead, they can typically be stored at room temperature, unless specified otherwise by the manufacturer for specific formulations.
