A caplet is a type of tablet that has a smooth coating and is usually longer in shape compared to regular tablets. Synonyms for caplet include capsule, pill, tablet, lozenge, troche, and pellet. Capsules are also smooth-coated medicine forms that are easier to swallow and dissolve quickly in the stomach. Pills, tablets, and lozenges are solid dosage forms that come in various shapes and sizes that may be coated or uncoated. Troches are dissolvable tablets that are held in the mouth to deliver medication slowly. Pellets are small, spherical-shaped tablets that can release medication over a prolonged period.
