79Step 9—repeat steps for each pharmaceutical item with related brands

#### 79 Step 9—repeat steps for each pharmaceutical item with related brands (1) For each brand (including delisted brands) of a pharmaceutical item with the same drug and manner of administration as the listed brand but a different form (the other pharmaceutical item), other than an exempt item, work out the price percentage difference of the brand for the data collection period ending on the same day as the data collection period of the listed brand. (2) The price percentage difference of a brand of the other pharmaceutical item is worked out using steps 1 to 5, reading references to the listed brand as references to the brand of the other pharmaceutical item. (3) If a brand of the other pharmaceutical item is a delisted brand on the final day, then the pricing quantity of the delisted brand on the final day is taken to be: (a) if there is a listed brand of the other pharmaceutical item on the final day—the pricing quantity of the listed brand of the other pharmaceutical item; or (b) if there is no listed brand of the other pharmaceutical item on the final day—the pricing quantity of the last listed brand of the other pharmaceutical item immediately before it was delisted. > Note: The pricing quantity of the brand on the final day is needed for working out the adjusted volume (step 2) and the average approved ex‑manufacture price (step 3). (4) For each pharmaceutical item with the same drug and manner of administration as the listed brand but a different form, other than an exempt item, work out the weighted average percentage difference of the brands of the pharmaceutical item (using steps 7 and 8).
