Baghdad’s ninth-century pharmacies were already state-regulated
The World Health Organization counts at least 2.6 million pharmacists and pharmaceutical workers worldwide. Their craft is older than the modern shop: Sumerian tablets list recipes, and Baghdad opened drug stores in 754 under the Abbasids—state-regulated by the ninth century.
Pharmacy is the science and practice of preparing, dispensing, reviewing, monitoring, discovering, producing, and advising on medicines so their use is safe, effective, and affordable. It links health, pharmaceutical, and natural sciences with the humanities. Practice splits into community and institutional settings; clinical pharmacy delivers direct patient care in hospitals, clinics, hospice, and increasingly community roles such as immunizations, point-of-care testing, and protocol-based prescribing. In places including Colorado, Canada, and Australia, pharmacists may prescribe or adapt prescriptions. U.S. and Canadian "drugstores" often sell far more than medicine. Disciplines include pharmaceutics, medicinal chemistry and pharmacognosy, and pharmacology (kinetics and dynamics)—boundaries blur with biochemistry. Pharmacology is sometimes called a fourth discipline yet remains a distinct biomedical science; pharmacists who pursue both take separate degrees. Pharmacoinformatics and pharmacogenomics add computational discovery and gene-linked response variation.
Pharmacists are medication experts optimizing therapy; the International Pharmaceutical Federation represents them globally with WHO. U.S. Board of Pharmacy Specialties recognizes fields from oncology to psychiatry; technicians dispense and administer under supervision but generally may not counsel patients in the U.S., where some states set pharmacist-to-technician ratios. UK medicines counter assistants can sell certain non-prescription medicines but not prepare prescription-only drugs. History runs deep: the Sushruta Samhita is an early medicinal compilation attributed to the sixth century BC (preserved text of the third–fourth century AD); Egyptian Ebers Papyrus (1550 BC) and Edwin Smith Papyrus record pharmacological knowledge; Dioscorides' first-century De Materia Medica shaped medieval formularies; China's Shennong Bencao Jing dates to the first century AD. In early Japanese imperial ranks under the Taihō (701) and Yōrō (718) codes, pharmacists outranked physicians—even the emperor's doctors.

Brazilian educators recently validated three entrustable professional activities for community clerkships—modern attempts to standardize what "competent" looks like behind the counter that Abbasid regulators already policed.
