The objective of this study was to evaluate the intended and unintended impact on pharmaceutical use and sales of three public reimbursement reforms applied to the prescription of statins: a Spanish generic reference pricing system, and two competing policies introduced by the Andalusian Public Health Service. ⋯ RP has been effective at reducing the volume of sales growth of the off-patent statins, yet its overall impact on sales of all statins has been relatively modest.
