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

Manufactured dose form	Solution for injection
Unit of presentation	Ampoule	The ampoule "bounds" the liquid
[Pack size]	10 ampoules in the box
Precise active ingredient	metoclopramide hydrochloride
Basis of strength substance	metoclopramide hydrochloride
Presentation strength (logical)	100 mg per volume contained in the unit of presentation	The amount of the dose form bounded in the unit of presentation
Presentation strength	100 mg per 20 mL
Concentration strength	5 mg per 1 mL

Example 2: A pack of 20 UDVs each containing 2mL of ipratropium bromide for solution for nebulisation

Manufactured dose form	Solution for nebulisation
Unit of presentation	Unit dose vial	The vial "bounds" the liquid
[Pack size]	5 vials in a sleeve, 4 sleeves in the box
Precise active ingredient	ipratropium bromide
Basis of strength substance	ipratropium bromide
Presentation strength (logical)	500 mcg per volume contained in the unit of presentation	The amount of the dose form bounded in the unit of presentation
Presentation strength	500 mcg per 2 mL
Concentration strength	250 mcg per 1 mL
