Caplets

Caplets are a type of solid pharmaceutical dosage form designed to resemble capsules in shape but produced as one compressed tablet. They are typically elongated and smooth to facilitate swallowing, and they may be coated or uncoated. Caplets are manufactured by compressing powdered active ingredients and excipients into a single, unified piece, and they often receive a film or sugar coating to mask taste, improve stability, or control release.

Caplets are distinct from capsules, which consist of a gelatin shell containing a powder or pellet fill. While both aim to deliver an accurate dose, caplets are single solid units without a dissolving shell. They are also related to tablets, but caplets are specifically formed into an oblong, capsule-like shape to improve swallowability and dosing uniformity. The manufacturing process emphasizes compressibility and flow properties of the powder blend, and coatings may be applied for taste masking, moisture protection, or controlled release.

Coatings used on caplets can be film coatings or sugar coatings. Film coatings are common in modern caplets and can be formulated to resist moisture, protect the stomach, or tailor the release profile. Some caplets are designed for rapid or delayed release, depending on the therapeutic goal and regulatory requirements for the drug product.

Common uses include analgesics, antipyretics, decongestants, and various over‑the‑counter or prescription medications. Patients are advised to swallow caplets whole with water unless the label or a healthcare provider instructions allow breaking or splitting. As with all medicines, caplets must be used according to dosing directions and stored according to label recommendations.
