The PCA data is at presentation level (this will allow you to identify the specific drugs that you require the data for). The PCA data is for items dispensed in England, we only hold data for items which have been dispensed and subsequently submitted to the NHSBSA for pricing. The data contains the number of prescription items and the quantity prescribed.
