Title:
Pharmacy

Context:
A Pharmacy Technician in the UK is considered a health care professional and often does not work under the direct supervision of a pharmacist (if employed in a hospital pharmacy) but instead is supervised and managed by other senior pharmacy technicians. In the UK the role of a PhT has grown and responsibility has been passed on to them to manage the pharmacy department and specialised areas in pharmacy practice allowing pharmacists the time to specialise in their expert field as medication consultants spending more time working with patients and in research. A pharmacy technician once qualified has to register as a professional on the General Pharmaceutical Council (GPhC) register. The GPhC is the governing body for pharmacy health care professionals and this is who regulates the practice of pharmacists and pharmacy technicians.

Question:
What is a main duty of the GPhC?

regulates the practice of pharmacists and pharmacy technicians
