What characterizes a sustained release or time release capsule?

  1. Softening and soothing effects on the skin

  2. Contains small drug particles settled at the bottom

  3. New type of liquid solution delivery

  4. Contains small amounts of the drug in separate balls that dissolve over time

The correct answer is: Contains small amounts of the drug in separate balls that dissolve over time

A sustained release or time-release capsule is designed to release medication gradually over an extended period. The correct answer, "Contains small amounts of the drug in separate balls that dissolve over time," accurately describes how these capsules work. The medication is typically contained in small beads or balls within the capsule, allowing for controlled release through dissolution over time. This method helps maintain a steady level of the drug in the body and can reduce the frequency of dosing. The other options are incorrect: A. Softening and soothing effects on the skin - This describes a topical medication or skincare product, not a sustained release capsule. B. Contains small drug particles settled at the bottom - This does not accurately depict a sustained-release capsule, as the controlled release is achieved through specific formulations inside the capsule. C. New type of liquid solution delivery - Sustained-release capsules are not typically associated with liquid solutions; they are solid dosage forms designed for gradual drug release.
