Other forms: capsules
A capsule is a small case holding one dose, swallowed whole. Take one capsule, a gelatin capsule, capsules and tablets.
The shell dissolves in the stomach, and coating it differently is how a medicine is made to release further down — which is why capsules must not be opened unless a pharmacist says so. A space capsule and a time capsule share the idea of a sealed container.
