Abstract
Pharmacy, one of the oldest health professions, has evolved over millennia from mystical herbalism and religious healing practices to a scientifically rigorous and globally regulated discipline. This comprehensive review traces the journey of pharmacy from its roots in ancient Civilisations-from the legendary Egyptian polymath Imhotep, often regarded as the first physician-pharmacist-through classical antiquity, the Islamic Golden Age and medieval monastic traditions, to the scientific enlightenment, industrial revolution and contemporary digital era. The article explores how ancient records such as the Ebers Papyrus and Mesopotamian clay tablets served as early pharmacopoeias. It highlights contributions of foundational figures like Galen, Dioscorides and Avicenna and examines how pharmacy developed in tandem with medicine, botany, alchemy and chemistry. The Islamic world’s preservation and advancement of pharmaceutical knowledge significantly influenced European practices during the Middle Ages and the Renaissance. The emergence of apothecaries, the professionalisation of pharmacy through regulatory frameworks and the impact of scientific and technological revolutions-including mass production, synthetic chemistry and biotechnology-are thoroughly analysed. The review also addresses the rise of clinical pharmacy, the shift toward patient-centred care and the modern-day challenges and innovations in global health, digital transformation and pharmaceutical education. Focusing on Africa’s unique contributions and current pharmaceutical landscape, the work underscores pharmacy's rich heritage and future potential on the continent. It concludes with a call to reclaim the pharmacy’s independence and redefine its role in a rapidly changing health ecosystem. Through a detailed historical lens, this study celebrates pharmacy as both an ancient art and a modern science, central to the pursuit of health and human flourishing across civilisations.
1. Origins of Pharmacy in Ancient Civilisations
Pharmacy began in ancient civilisations, notably Egypt and Mesopotamia, where early practitioners used herbs, minerals and animal parts for healing. In Egypt, Imhotep-regarded as the first physician-pharmacist-pioneered scientific methods in healing and is credited with writing one of the earliest medical texts1. The Ebers Papyrus (c. 1550 BCE) documented over 800 medical prescriptions and reflects a structured approach to medicine and pharmacy2. In Mesopotamia, clay tablets containing over 700 prescriptions marked the early use of written pharmacopoeias. Other ancient cultures, including those in India and China, independently developed herbal and drug traditions. Ancient Indian Ayurvedic texts and Chinese Materia medica laid the groundwork for comprehensive healing systems that survive today.
3. The Arabic Golden Age (8th-14th Century)
The Arabic Golden Age marked a profound leap in pharmaceutical knowledge. Scholars such as Avicenna (Ibn Sina) and Al-Razi synthesised Greek and Roman teachings, enriched them with Persian and Indian insights and advanced chemical extraction methods, distillation and dosage formulation3. The establishment of Bimaristans (hospitals) and pharmacy shops in cities like Baghdad institutionalised pharmacy as a distinct profession. Avicenna’s Canon of Medicine remained a central pharmacological reference in Europe and the Middle East for centuries, laying the foundations of regulatory systems and pharmaceutical ethics.
4. Pharmacy in Medieval Europe
With the decline of Roman influence, Europe’s pharmaceutical knowledge was preserved in monasteries, where monks cultivated medicinal herbs and translated Arabic texts4. By the 13th century, pharmacy began separating from medicine. The 1231 Edict of Frederick II in Sicily formally separated the roles of physician and pharmacist and introduced legal regulation via pharmacy guilds. The emergence of apothecaries-retailers of medicinal products-marked the evolution of drug preparation and sale as a specialised field.
5. The Renaissance and Enlightenment
The Renaissance revived scientific inquiry and classical learning. Pharmacy benefited through advances in botany and chemistry, leading to the founding of botanical gardens and academic departments of pharmacognosy, such as at Padua (1545)3. Pharmacists began employing empirical and experimental methods in drug preparation. The printing press allowed rapid dissemination of pharmaceutical knowledge and standardisation of herbal texts and compounding techniques.
6. Industrial Revolution and Birth of Pharmaceutical Companies
The Industrial Revolution introduced machinery and chemical synthesis, transforming pharmacy from an artisanal to a scientific discipline. Drugs were mass-produced and the first pharmaceutical companies emerged. Scientific discoveries, including the isolation of morphine (1806) and quinine (1820), revolutionised disease treatment and led to global expansion in pharmaceutical trade4. Professional journals, regulatory bodies and pharmacy education institutions emerged, setting global standards.
7. 20th Century:
Clinical Pharmacy and Modern RegulationThe 20th century witnessed the rise of clinical pharmacy, which emphasised patient safety, rational drug use and healthcare team collaboration. The Pharm.D. degree became a global gold standard5. Pharmacy curricula expanded to include biopharmaceutics, pharmacokinetics and counselling. Regulatory reforms followed tragedies like the thalidomide crisis, prompting legislation such as the 1938 U.S. Food, Drug and Cosmetic Act and leading to stronger roles for regulatory bodies like the FDA and WHO6.
8. Digital Transformation in Pharmacy
Digital technology is reshaping pharmacy globally. Innovations such as tele pharmacy, AI-based drug discovery, automated dispensing and electronic prescriptions enhance patient access and safety7. These tools proved especially vital during the COVID-19 pandemic, which drove global reliance on virtual health platforms. However, data security, digital literacy and online counterfeit medicines persist.
9. The Role of Pharmacy in Global Public Health
Pharmacists now play a frontline role in global health, especially in low- and middle-income countries (LMICs). They support immunisation programs, disease prevention, health education and medication access8. Modern pharmacy training increasingly incorporates public health, epidemiology and policy-making. Multilateral cooperation is crucial for building sustainable pharmaceutical systems.
10. Pharmacy in Africa: Legacy and Renaissance
Africa’s pharmacy heritage dates back to Imhotep and the Ebers Papyrus. Colonialism disrupted Indigenous pharmaceutical systems, but post-independence, Africa has sought to regain autonomy through education, local manufacturing and improved regulation9. South Africa’s Pharmacy Act 1885 formalised the profession6. Today, regional production hubs, herbal research centres and professional associations are building momentum, despite challenges such as counterfeit drugs, weak infrastructure and a lack of investment.
11. Future of Pharmacy: Global and Digital
The future of pharmacy lies in personalised medicine, pharmacogenomics and technology-driven care. Pharmacists will act as healthcare integrators, linking diagnostics, drug therapy and patient outcomes. Technologies such as blockchain, 3D printing, mobile apps and big data analytics transform how drugs are discovered, distributed and monitored5. Pharmacy education is adapting through simulation labs, virtual learning and interprofessional collaboration. As global health challenges grow, pharmacy must evolve with them.
12. Conclusion
The pharmacy has bridged science and healing across millennia from its mystical origins in temple rituals to modern, tech-enabled therapeutics. Though often overshadowed by medicine, pharmacy has long held its distinct legacy of innovation and service. Contributors like Imhotep, Dioscorides, Avicenna and Galen paved the way for scientific medicine and pharmacy. Africa’s heritage in the field is rich and must be reclaimed and reimagined for the 21st century. The pharmacy’s destiny is to lead in health innovation, patient care and global health equity, anchored in timeless principles and future-facing science.
