The Classification of Pharmaco-Therapeutic Referrals (CPR) is a taxonomy focused on defining and grouping together situations requiring a referral from pharmacists to physicians (and vice versa) regarding the pharmacotherapy used by the patients.

[1] It is a simple and efficient classification of pharmaco-therapeutic referrals between physicians and pharmacists permitting a common inter-professional language.

[2] It is adapted to any type of referrals among health professionals, and to increase its specificity it can be combined with ATC codes, ICD-10, and ICPC-2 PLUS.

[citation needed] It is a part of the MEDAFAR Project, whose objective is to improve, through different scientific activities, the coordination processes between physicians and pharmacists working in primary health care.

It also includes a glossary of 51 terms defined by consensus, an alphabetical index with 350 words used in the rubrics; and a standardized model of inter-professional referral form, to facilitate referrals from community pharmacists to primary care physicians.
