This applies to all data. Different types of sources will have drug information.
To find the dose form of a drug the RELATIONSHIP table can be used where the relationship_id is ‘Has dose form’.If the drug is a liquid, quantity stands for the total amount dispensed or ordered of ingredient in the units given by the drug_strength table (typically stored as some measure of volume e.g. milliliters etc). If the unit from the source data does not align with the unit in the DRUG_STRENGTH table the quantity should be converted to the correct unit given in DRUG_STRENGTH.
