Which type of capsule has a rigid outer shell?

Hard-shelled capsules are characterized by their rigid outer shell, typically made from gelatin. This hard exterior is designed to encase powdered or granular ingredients, enabling the capsule to maintain its shape and protect its contents. The hard shell also facilitates the controlled release of the active ingredients once ingested, as it dissolves in the stomach or intestines.

These capsules can be easily opened if necessary, which allows for flexible dosing or mixing of the contents with food or liquid for patients who may have difficulty swallowing. The production of hard-shelled capsules also allows for a longer shelf life of the medication contained within, preserving its potency compared to other forms of medication delivery.

In contrast, soft gel capsules have a more flexible, gel-like outer shell designed for liquid or semi-solid contents. Liquid medications are not typically associated with capsules at all, as they are administered in their liquid form. Scored tablets are designed for easy breaking and dosage adjustment but have a solid form rather than encapsulation. Therefore, hard-shelled capsules stand out as the correct response regarding capsules with a rigid outer shell.
