Waite %J Archive of "Canadian Pharmacists Journal : CPJ". %D 2019 %R 10.1177/1715163519852975 %X Recognizing their unique, widely accessible position in community pharmacies and expertise in drug knowledge, Canadian and international community pharmacists have taken on expanded roles in health care delivery, including prescriptive authority. The level of authority varies per jurisdiction, broadly categorized as dependent or independent prescribing depending on the level of autonomy afforded to pharmacists. The former requires pharmacists¡¯ prior authorization from a prescriber, known as ¡°Collective Agreements¡± in the United States, ¡°Supplementary Prescribing¡± in the United Kingdom, or ¡°Delegated Authority¡± in Ontario, Canada.1 Independent prescribing, on the other hand, provides pharmacists with the legal authority to prescribe, and this can be in the form of managing existing drug therapy as well as initiating drug therapy %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6610502/
