The title of the “Father of Pharmacy” is often attributed to different historical figures based on varying interpretations of pharmacy’s evolution, contributions to medicinal practices, and the scientific advancements that have shaped the profession. However, one name that frequently stands out in the history of pharmacy is that of Galen of Pergamon (c. 129 – c. 200/216 AD), an influential Greek physician and philosopher whose work laid the foundation for both medicine and pharmacy as we know them today. This article explores the life of Galen, his contributions to the field, and why he is often recognized as the first father of pharmacy. On February 13, 1946, in Yogyakarta an organization was formed called “Persatuan Ahli Pharmasi Indonesia” as a forum to gather all workers who dedicate their work in the field of pharmacy, Persatuan Ahli Pharmasi Indonesia hereinafter abbreviated as “PAFI.

1. A Brief Biography of Galen
Galen was born in Pergamon, a thriving city in Asia Minor (modern-day Turkey), during the Roman Empire. He came from a wealthy family, and his father, Aelius Nicon, was a well-respected architect. Encouraged by his father to pursue education, Galen studied philosophy and medicine at various institutions, including Alexandria, which was one of the premier centers of learning at the time.
Galen’s formal education encompassed a wide range of subjects, including medicine, philosophy, anatomy, and the study of natural sciences. His comprehensive understanding of these disciplines enabled him to develop a holistic view of health and disease. After completing his studies, Galen returned to Pergamon, where he began to practice medicine.
His career took a significant turn when he moved to Rome around 162 AD. There, he gained fame for his medical practice and became the personal physician to several emperors, including Marcus Aurelius. Galen’s work and writings during this period would leave a lasting impact on the field of medicine and pharmacy.
2. Galen’s Contributions to Pharmacy
Galen’s contributions to pharmacy and medicine are vast, and his influence can be observed across several key areas:
a. Pharmacology and Formulation
Galen is renowned for developing a systematic approach to the preparation and formulation of medicinal compounds. He categorized drugs based on their properties, actions, and effects on the human body. His extensive writings detailed the methods of preparing medicines, including the processes of mixing, boiling, and grinding various substances.
One of Galen’s most significant contributions was the introduction of the concept of “galenicals,” a term used to describe medicinal preparations that were compounded by pharmacists. These included a variety of forms such as powders, ointments, syrups, and elixirs. Galen emphasized the importance of the preparation methods, arguing that the way a drug was prepared could influence its therapeutic effects.
His work on drug formulation established principles that remain relevant today. The processes he described for compounding medications set the stage for modern pharmacy practices, where the preparation and dispensing of medications require precision and an understanding of their interactions.
b. The Theory of Humors
Galen’s medical philosophy was largely influenced by the ancient theory of humors, which proposed that the body was composed of four fluids: blood, phlegm, yellow bile, and black bile. According to this theory, health was achieved when these humors were in balance, and illness resulted from their imbalance.
Galen expanded upon this theory, integrating it with his observations and clinical practices. He believed that medications could restore balance among the humors, and he categorized drugs according to their effects on these bodily fluids. This understanding of drug effects and their application in treatment demonstrated a significant leap toward a more systematic and scientific approach to medicine and pharmacy.
While the theory of humors has since been discredited, it played an important role in the evolution of medical thought and practice for centuries. Galen’s elaboration of this concept influenced countless physicians and pharmacists throughout history, shaping the field until the advent of modern medicine.
c. Anatomical Studies
Galen’s work in anatomy also contributed to his legacy as a father of pharmacy. His dissections of animals allowed him to gain insights into human anatomy, although he never performed human dissections due to cultural and legal restrictions of the time.
His observations of anatomical structures led to numerous insights into physiology and the function of organs, which were documented in his numerous treatises. His authoritative texts dominated medical education for over a millennium, serving as the primary source of anatomical knowledge until the Renaissance.
The impact of Galen’s anatomical studies extended into pharmacy, as understanding the human body and its systems is crucial for determining how drugs interact with different organs and tissues. His emphasis on the importance of anatomy and physiology laid the groundwork for future pharmacological studies.
3. Galen’s Legacy in Pharmacy and Medicine
Galen’s influence on pharmacy and medicine cannot be overstated. His work served as a bridge between ancient medical practices and the scientific approaches that emerged during the Renaissance. Several key aspects of his legacy include:
a. Standardization of Medicinal Practices
Galen’s emphasis on the systematic preparation of medications and the careful documentation of medicinal properties set the stage for the standardization of pharmacy practices. He advocated for rigor and precision in the preparation of medicines, laying the groundwork for the professionalization of pharmacy as a distinct field.
This approach paved the way for the creation of official pharmacopoeias in later centuries, where standardized drug formulations and practices were compiled to ensure the quality and efficacy of medications.
b. Influence on Later Physicians and Pharmacists
Galen’s texts became essential reading for physicians and pharmacists throughout the Middle Ages and the Renaissance. His principles and methods shaped medical education for centuries, and many of his teachings were accepted as authoritative in both medicine and pharmacy.
Notable figures, such as Avicenna, Paracelsus, and Andreas Vesalius, built upon Galen’s work, leading to significant advancements in the understanding of medicine and pharmacy. His influence can still be seen in contemporary pharmacy education and practice, where his ideas about compounding and drug formulation continue to be relevant.
c. Integration of Pharmacy and Medicine
Galen’s work helped solidify the relationship between pharmacy and medicine, emphasizing the importance of collaboration between pharmacists and physicians. His writings advocated for the need for trained practitioners who could effectively understand and dispense medications, laying the groundwork for the modern interdisciplinary healthcare teams we see today.
4. Critiques and Limitations
Despite his monumental contributions, Galen’s work was not without its limitations and critiques. His reliance on animal studies for anatomical knowledge resulted in inaccuracies when applied to human physiology. Many of his theories, particularly the concept of the humors, were based on philosophical speculation rather than empirical evidence. As a result, they were challenged and eventually discarded with the advancement of medical knowledge.
The Renaissance and the subsequent development of modern medical practices prompted a re-evaluation of Galen’s work, leading to both admiration for his contributions and critique of his limitations. However, it is important to acknowledge that his ideas were products of their time and that they represented a significant step toward a more scientific understanding of health and disease.
Conclusion
While the title of the “Father of Pharmacy” may vary depending on perspective, Galen of Pergamon is undoubtedly one of the most influential figures in the history of pharmacy. His systematic approach to drug preparation, his contributions to the understanding of anatomy and physiology, and his emphasis on the importance of medication in healthcare laid the foundation for the evolution of pharmacy as a profession.
Galen’s legacy endures today in the practice of pharmacy, where the principles he established continue to influence the formulation and dispensing of medications. By bridging the gap between ancient practices and modern scientific medicine, Galen’s work has left an indelible mark on the field of pharmacy, making him a fitting candidate for the title of the first father of pharmacy. As the profession continues to evolve, the insights and methodologies developed by Galen will undoubtedly remain a cornerstone of pharmaceutical practice.
