Item unit
In IWRS, you have the flexibility of deciding how you prefer to manage your investigational (IMP) and supplementary products for shipping, inventory, dispensation, and other purposes. These options are as follows:
-
Product unit: maintain your products as individual instances, such as a vial of infusion liquid, stick of powder, blister of tablets, and so on.
For instance, if your product is Aspirin in tablets packed in blisters, then a single blister of Aspirin is an accountable product unit in IWRS that you can ship, store, dispense to subjects, and otherwise manage.
-
Container unit: maintain your products in packages of product units, such as a box containing a specific number of product units.
For instance, if your product is Aspirin in blisters and you pack them into boxes of 10 blisters each, then a single box of Aspirin blisters is an accountable container unit in IWRS that you can ship, store, dispense to subjects, and otherwise manage.
Important
If no container units are configured in IWRS, then all IMP handling—shipping, inventory, and so on—occurs in product units.
