Products counts every marketed product across all strengths and forms, not companies. Companies is the number of companies marketing that molecule; the same company may appear under several molecules, so the column does not add up to a class total. Market size sits on each molecule's own page, valued at national price rather than transaction price. Figures are as at 2026-08-28.
