Can pharmaceutical hard gelatin empty capsules help mask the taste and odor of the encapsulated substance?

Pharmaceutical hard gelatin empty capsules can indeed be used to mask the taste and odor of encapsulated substances. The capsule wall is made of gelatin and has a certain barrier performance, which can protect the internal drugs from the influence of the external environment, and also mask or weaken the odor or unpleasant smell of the drugs themselves.
For example, some capsules may contain drugs with a pungent or unpleasant odor inside, and in order to make patients more comfortable to use, capsule shells made of gelatin are used for wrapping. In this way, patients only need to swallow the capsule without direct contact with the medication, thereby reducing the interference of adverse taste or odor of the medication.
