What distinguishes a caplet from other tablet forms?

A caplet is specifically distinguished from other tablet forms primarily due to its unique shape and coating. It is oval in shape, which is reminiscent of a capsule, and it is coated, making it easier to swallow and providing a smooth surface for ingestion. The coating can also help mask unpleasant tastes and enhance the stability of the medication.

While there are other forms of tablets that may have distinguishing features—such as notching for easy splitting, designs for extended release, or specific ingredient compositions like antacids—these characteristics do not apply universally to caplets. The defining aspects of the caplet being an oval shape and having a coating are what set it apart from the broader category of tablets.
