What distinguishes caplets from other medication forms?

Caplets are specifically distinguished from other medication forms by their oval shape, which resembles that of a capsule but in a solid tablet form. This design allows for easier swallowing compared to traditional round tablets. Caplets typically have a smooth coating that helps them go down more easily, making them a preferred option for many patients who may struggle with swallowing larger or uncoated tablets.

The other options highlight characteristics that do not apply to caplets. For instance, stating that caplets are cylindrical does not accurately reflect their traditional oval shape. Additionally, indicating that they are only available in liquid form contradicts the definition of caplets as solid oral dosage forms. Lastly, suggesting that caplets are designed for injection is inaccurate, as injections refer to a completely different delivery method compared to oral administration, which is what caplets are designed for. Thus, the oval shape is the key feature that clearly identifies caplets among different medication forms.
