Compressed into small, circular or oblong-shaped discs, tablets are solid forms of medication. Caplets are smaller versions of tablets with a slicker exterior, making them simpler to swallow. Both caplets and tablets can be crushed and divided into smaller dosages.
Tablets and caplets are quite similar pharmaceutical forms. Both are coated with sugar and other substances to aid in the gradual release of medication into the body. They are produced at a lower cost than other forms of medicine. Caplets and tablets have longer shelf life than other kinds of medication, according to AllStarHealth.com.
