Items dispensed (England, NHSBSA). Market volume counts every item NHSBSA lists, mapped to a product or not; the producer and product figures count mapped items only. Newest release counted: FOI-03965. Months counted from FOI-03965 (Jun 2020 to May 2021); each month comes from its newest release.

NHSBSA dispensing figures cover England only and count dispensed items, not patients or prescriptions. They are lagged by several months, revised retrospectively and unvalidated by NHSBSA, and their units are not standardised because these products are not on the NHSBSA drug database. One product can appear under many spellings, potency notations and pack sizes.
