Capsules are a type of solid dosage form that is composed of a single unit that is intended to be taken orally. The "MR" in the name of the capsule may refer to a modified release formulation, meaning that the active ingredient in the capsule is designed to be released slowly over a certain period of time, rather than all at once. The exact details of the MR capsule, including its composition, active ingredient, and recommended dosage, can vary and should be determined by a healthcare provider.
