In pharmaceutical terms, a capsule is primarily defined as a dosage form in which the active ingredients are encased in a gelatin shell. The gelatin shell serves to hold the medication, making it easier to swallow and protecting the active ingredients from environmental factors such as light or air. Capsules can be filled with powder, liquid, or granulated substances, and they provide a convenient way to deliver medications while allowing for various release profiles.

The other options refer to different forms of pharmaceutical preparations. For example, the option about being coated with materials that do not dissolve in the stomach pertains to enteric-coated tablets, which are designed to dissolve in the intestine rather than the stomach. The third option refers to topical preparations, which are designed to be applied to the skin for localized effects. The last option discusses rectal or vaginal inserts, which are specifically formulated for use in these areas. Understanding the specific characteristics of various dosage forms helps healthcare professionals choose the best method of medication delivery for their patients.
