Continuous presentation: bounded by container; liquid dose forms

Examples: parenteral solutions, unit dose nebuliser solutions

The unit of presentation usually either uses the same word (even though it is a different concept) as the (package item) container, or the (package item) container is a more granular concept and the unit of presentation uses a less granular term. Presentation strength is expressed as "per the amount of liquid bounded by the unit of presentation" but concentration strength is per mL (and therefore is often different).

Example: A pack of 10 ampoules each containing 20mL of metoclopramide hydrochloride for solution for injection
