The Royal Pharmaceutical Society of Great Britain (RPSGB) existed from its founding as the Pharmaceutical Society of Great Britain in 1841 until 2010. The word "Royal" was added to its name in 1988. It was the statutory regulatory and professional body for pharmacists and pharmacy technicians in England, Scotland and Wales. In September 2010, the regulatory powers of the Society were transferred to the newly formed General Pharmaceutical Council (GPhC). The RPSGB became the Royal Pharmaceutical Society (RPS) at that time and retained its professional leadership role; the "Great Britain" part of the name was dropped for day-to-day purposes.
Before the establishment of the GPhC and the transfer of regulatory power, the primary objective of the RPSGB was to lead, regulate, develop and promote the pharmaceutical profession. All pharmacists in Great Britain had to be registered with the Society in order to practise, and the Society was unusual amongst healthcare regulators that it had its own inspectorate. To become a member of the Society an individual usually had to complete a MPharm or (if graduating before 2000) a BPharm or BSc (pharmacy) degree, 52 weeks of pre-registration training and pass a registration examination. This gave them the right to use the post-nominal letters MRPharmS (Member of the Royal Pharmaceutical Society) and to practise as pharmacist in Great Britain. Fellowships (FRPharmS) were also awarded for pharmacists with long standing and outstanding commitment to the profession.
The register of pharmacists is now held by the GPhC, and it is this body which now controls registration and fitness to practise. The Royal Pharmaceutical Society now provides members with the post-nominals 'MRPharmS' and those members who have been awarded fellowships with 'FRPharmS'.
