HISTORY OF PHARMACY IN THE WORLD
Humans have made tremendous efforts in the prevention and treatment of diseases. The history
of Pharmacy dates as far back as 4000B C, when the ancient Sumerians who lived in the modern
day Iraq and parts of Kuwait used and documented plants, animal, and mineral substance used to
alleviate distress and cure illness. There is also historical evidence supporting attempt to cure
diseases with plants and plant extract in parts of Asia and Africa as far back as 1500 BC.
At that time the practitioners of the healing art combined the roles of priests,
Pharmacists/Herbalists and Physicians, a practice which still continues in some communities
today even though their approach viewed in modern times may not necessarily be scientific.
It was believed that the first apothecary’s state was established in Baghdad in the Eight century.
Apothecary is a term commonly used to describe a medical practitioner/professional who
supplies medicines. The modern day Pharmacist has taken over this role. However, the word is
still sometimes used to refer to a retail Pharmacy or a Pharmacist who owns one.
Around the beginning of the second millennium, in places like Italy and North Africa, the use of
relatively potent medicines had increased and the need for persons with special skills for the safe
preparation and who knew the uses of those medicines, understood the benefits and also the risks
associated with their use was increasingly required. This led to the issuing of the Constitution of
Melfi of 1231 by Roman Emperor Fredrick II the king of Sicily. This constitution
differentiated the roles of Physicians from Pharmacists.
PASU 3
But before the separation of the two professions, Galen (130 – 200 AD) practiced and taught
both Pharmacy and Medicine in Rome. He established some basic principle for preparing and
compounding medicines. The word ‘Galenical’ is associated with his name. This refers to a class
of pharmaceuticals compounded by mechanical means.
The time of creation of the profession of Pharmacy as we currently have it in the world differs
from nation to nation. But it is important to note that irrespective of the time of creation, the
existence of Pharmacy as a distinct occupational and professional entity has always been linked
with the regulation of medicine supply and use, and the maintenance of defined standards of
practice.
Initially, the training in pharmacy took the form of apprenticeship and learning by ‘on the job’
training and experience but in the 19th century the first modern era Pharmacy schools began to be
established. Today, to become a Pharmacist, the individual has to be trained in the University for
a period of Five (or Six) years.
Because of the need to have a sub – cadre that assist the Pharmacists in performing his role,
those individuals were called by different names (like Pharmacy Aides, Pharmacy Clerks,
Pharmacy Assistants, Pharmacy Helpers, Pharmacy Support Personnel) were employed.
This sub – cadre is now called a Pharmacy Technician. They also are expected to undergo formal
training (in Nigeria in institutions called Colleges of Health.
Current trend is that the Pharmacist focus on activities such as checking drug interaction and
contraindications, selection of therapy, pharmaceutical care, and patient care outcomes, while the
Pharmacy Technician focus on dispensing of medicines and preparation of medicines and
records keeping activities under the supervision of the Pharmacists.
In summary, Pharmacy as a distinct profession in relation to Pharmacist’s role has had four eras:
1. The Traditional Era (Creation of the profession – 1930): Formulating and dispensing drugs
from natural source.
2. Scientific Era (1930 – 1960): Development of new drugs, scientific testing, mass production
of synthetic drugs and antibiotics.
3. The Clinical Era (1960 – 1990): Pharmacist were exposed to give drug information warnings,
advice and suggestion to patients.
PASU 4
4. The Pharmaceutical Care Era (1990 – to date): That is the current era where the practice of
Pharmacy is focused on ensuring positive outcomes for drug – related therapies.

MAINTENANCE OF GOOD CONDUCT AND ETHICS
The main role of the Pharmacy profession is the provision of medicines and other health care
products and to provide pharmaceutical care and help people and community to make the best
use of them.
A patient’s welfare takes priority in every aspect of pharmaceutical care. It is very important to
take measures that lead to the satisfaction of patients.
A Pharmacy Technician (in assisting the Pharmacist to provide pharmaceutical care) must pay
attention to three areas:
1. Dressing/Appearance
Patient will always make assumptions about you based on initial impressions, some which may
be difficult to change. Thus, the need for proper dressing cannot be overemphasized. A white
overall with blue collar with a tag having your name and Pharmacy Technician printed on
it is recommended.
Good communication largely depends on common sense. Always ensure that what you say, how
you say it and your body language are properly blended together so that patient does not get
mixed or confused message from you. According to M. M. Moody et al, it is generally agreed
that communication is 10 % what you say, 40 % how you say it and 50 % your body
language.
The tone – Don’t be harsh, let your tone be as tender and as gentle as possible
Speed – Do not speak too fast such that the patient cannot comprehend or too slow such
that the patient is irritated
PASU 18
Volume – Make your voice audible enough to be heard but not too loud to the extent of
embarrassing the patient
Vocal Mannerisms – This should be avoided as much as possible
c) Body Language:
Gestures – This is the movement made with a part of the body in order to express
meaning or communicate an instruction
Facial Expression – Let your facial expression put the patient at ease. A sad or angry
facial expression can make patients uncomfortable
Eye Contact – Maintain eye contact most of the time, don’t stare to the extent of
embarrassing the patient and don’t keep looking away. It makes patient feel either you
don’t know what you are talking about or you don’t care
Physical Contact and Personal Space – Respect patient’s personal space, it makes
patient more comfortable to receive instruction
Body Posture – This is the position your body assumes while speaking with patient.
Sitting sideways with your legs on the table shows an attitude of unconcern
3. The Environment
The Noise Level – A noise environment can be irritating and distracting and this prevents
patients from receiving proper instructions
The Cleanliness – This refers to the degree to which the pharmacy is kept clean.
No smoking
