A capsule is a type of medication that is designed to be swallowed whole. The capsule contains the active drug, as well as excipients, such as fillers and lubricants, which help to provide a convenient and consistent form of the medication. Capsules can be made of various materials, including gelatin and plant-based materials, and can be formulated to release the drug immediately or over a prolonged period of time. The capsule form of medication is convenient and easy to swallow, making it a popular choice for many patients. It is important to follow the instructions on the label and to take the medication exactly as prescribed by a healthcare provider. The contents of the capsule should not be crushed, broken, or chewed, as this can alter the release and efficacy of the drug.
