Pellets are a type of solid dosage form that are small, round, and often cylindrical in shape. They are used in pharmaceuticals as a way to deliver medications and active ingredients in a controlled manner. Pellets can be made from a variety of materials, including waxes, resins, and polymers, and they can be designed to dissolve at specific rates in order to release their active ingredients over time. They are often used in products such as oral and nasal sprays, and can also be used in other forms of drug delivery, such as implants.
