What distinguishes a caplet from other oral medications?

A caplet is specifically distinguished as a solid dosage form that is designed for easy swallowing. The design of a caplet combines the convenience of a tablet with the smoothness of a capsule, providing a coating that makes it less prone to breaking and easier to swallow compared to traditional tablet forms. This is particularly advantageous for patients who may have difficulties swallowing larger pills.

Caplets typically have a more rounded edge and an oblong shape, which enhances their swallowability and helps in reducing gag reflex. This design is important in ensuring patient compliance, especially in populations such as the elderly or people with certain medical conditions that affect their ability to swallow.

The other options describe different forms of medications that do not align with the characteristics of a caplet. A liquid medication in a glass vial references a completely different dosage form, while a medication that dissolves in the stomach pertains to how certain medications may work rather than their physical form. Powder medications for external application denote a topical use, which is not relevant to oral medications like caplets.
