Sustained-release formulations are designed to release the active ingredient slowly over time, allowing for a prolonged therapeutic effect and reducing the frequency of dosing. Among the options provided, capsules are often utilized for sustained-release medications due to their versatility in formulation.

Capsules can be filled with a variety of substances, including coated beads that dissolve at different rates or combinations of fast and slow-release materials. This allows for a controlled release of the active pharmaceutical ingredient (API) over an extended period. By using specific polymer coatings or formulations within the capsule, the release profile can be carefully designed to meet therapeutic needs.

In contrast, ointments are typically used for topical applications and do not align with the concept of sustained oral release. Syrups are liquid formulations that generally provide rapid absorption and immediate action, lacking the sustained-release property. Inhalers, while effective for delivering medications directly to the lungs, do not maintain a sustained release of medication in the systemic circulation over an extended time. Therefore, capsules stand out as a common choice for sustained-release formulations in the pharmaceutical industry.
