Pharmacology is the study of how drugs interact with living organisms and their physiological effects. It includes the study of drug composition/properties, interactions, therapeutic uses, and toxicity. Pharmacology is divided into pharmacodynamics, which studies how drugs act on the body, and pharmacokinetics, which studies how the body affects drugs. Oswald Schmiedeberg is considered the father of modern pharmacology, establishing the first pharmacology institute in the 19th century where he studied anesthetics, sedatives, and other compounds.

1.1 Pharmacology- An Introduction
The word pharmacology is derived from two Greek words, pharmacon meaning a drug, and logos meaning an opinion or reason. It can be defined as
“The science which deals with the history, source, physical properties, chemical properties, compounding, biochemical effects, physiological effects, mechanism of action, absorption, distribution, biotransformation, excretion, therapeutic and other uses of drugs, is called pharmacology.”
“The study of a substance that interacts with the living system through chemical processes especially by binding to regulatory molecules and activates or inhibits normal body processes”
“The science of substances used to prevent, diagnose and treat disease.”
Drug:
The word drug comes from Drogue meaning a dry herb. A drug can be defined as:
“A substance, material or product used for the purpose of diagnosis, prevention and relief of symptoms or cure of disease.”
WHO defines drug as:
“A substance, material or product used or intended to be used to modify or explore the physiological processes or pathological states for the benefit of the recipient.”
General Features of a Drug:
• Variability in molecular size
• Variability in shape
• Variability in chemical nature
• Variability in lipid/water partition coefficient
• Variability in degree of ionization
• Physical Properties
• Variability in molecular size
Smaller sized molecules are easily absorbed than larger molecules. Normally the molecular weight is between 100-1000 but may be higher or lower. Streptokinase is an example of large molecular weight drug while lithium or nitric oxides are of small molecular weight.
• Variability in shape

In a broad sense, the pharmacology deals with the study of drugs and their interactions with living systems. This study includes sources, chemical properties, dose, biological effects, therapeutic uses, and adverse effects of drugs. i.e. Pharmacology is the study of how drugs act on biological systems and how the body responds to the drug.
It comprises all aspects of knowledge about drugs, but most importantly those that are relevant to effective and safe use for medicinal purposes. Pharmacology integrates the knowledge of many disciplines, including medicine, pharmacy, dentistry, nursing, and veterinary medicine. This integrative nature allows pharmacology to make unique and significant contributions to human health.
Pharmacology is crucial for:
discovering new medicines to help fight diseases
improving the effectiveness of medicines
reducing unwanted side effects of medicines
understanding why individuals differ in the way they respond to certain drugs, and why some others cause addiction
This presentations includes information about definition of pharmacology, history, nature and sources of drugs, different terms used in Pharmacology, Essential Drugs concept, Routes of Drug Administration, and Agonist and Antagonist.

"Nothing in Life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less."
- Marie Curie
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. DEFINITION OF
PHARMACOLOGY
Pharmacology is branch of biology that
concerned with study of drug action and the
effects of living organisms with drugs .
Derived from Greek word pharmakon which
means drugs
This subject embodies drug composition and
properties, interactions, toxicology, therapy,
and medicinal uses such as application and
ant pathogenic capabilities.
Pharmacology is subdivided into two
categories :
1. Pharmacodynamics : deals with
chemical interactions with body/cell
receptors
2. Pharmacokinetics : deals with the four
stages of chemicals passing through the
body: absorption,
distribution, metabolism and excretion.
3. More specifically it is study of the interaction
that occur between living organisms and
chemicals that affect normal and abnormal;
biochemical function
Pharmacology is the study of the sources,
uses, and mechanisms of action of drugs. That
is what the body does to drugs
(pharmacokinetics) and what drugs do to the
body (pharmacodynamics)
In contrast Pharmacy is health service
profession concerned with application of
principals learned from pharmacology in its
clinical settings
4. Pharmacology is crucial for:
•discovering new medicines to help
fight diseases
•improving the effectiveness of
medicines
•reducing unwanted side effects of
medicines
•understanding why individuals differ
in the way they respond to certain
drugs, and why some others cause
addiction
6. Therapeutics: The branch of pharmacology that deals with
the art and science of treatment of disease. It is the
application of pharmacological information together with the
knowledge of disease, for the prevention and cure of the
disease.
Toxicology: branch of pharmacology which includes the
study of adverse effects of drugs on the body. It deals with
the symptoms, mechanisms, treatment and detection of
poisoning caused by different chemical substances.
The main criterion is the dose. Essential medicines are
poisons in high doses and some poisons are essential
medicines in low doses
7. Clinical Pharmacology: Clinical pharmacology is the
scientific study of drugs in man. It includes pharmacokinetic
and pharmacodynamic investigations in healthy or diseased
individuals. It also includes the comparison with
placebos, drugs in the market and surveillance
programmers.
Posology: Posology deals with the dosage of drugs.
Example includes paracetamol given as one tablet of
500mg thrice a day.
Neuropharmacology : study of effect of drug on central
and pheripheral nervous system
Pharmacogenetics: Branch of pharmacology dealing with
the genetic variations that cause difference in drug
response among individuals or population
Chemotherapy: Chemotherapy refers to the treatment of
diseases by chemicals that kill the cells, specially those of
microorganisms and euplastic cells.
8. Pharamcogenomics: Pharmacogenomics is the broader
application of genomic technologies to new drug discovery and
further characterization of older drugs.
Pharmacoepidemiology: Pharmacoepidemiology deals with
the effects of drugs on a large population. The effects may be
good or harmful.
Pharmacognosy: Pharmacognosy is the identification
of drugs by just seeing or smelling them. It is a crude method
no longer used. Basically it deals with the drugs in crude or
unprepared form and study of properties of drugs form natural
sources or identification of new drugs obtained from natural
sources.
Comparative Pharmacology: Branch of pharmacology
dealing with the comparison of one drug to another belonging
to the same or another group
9. History of Pharmacology
Pharmacology emerged as its own discipline in the 19th
Century, branching off from research done in fields of science
such as organic chemistry and physiology.
Oswald Schmiedeberg
who was born in what is now Latvia in 1838, is considered the
father of pharmacology. His doctoral thesis was on the
measurement of chloroform levels in blood, and he went on to
become a professor of pharmacology at the University of
Strasburg, where he ran an institute of pharmacology. There, he
studied chloroform, which was used as an anesthetic, chloral
hydrate, a sedative and hypnotic, and muscarine, a compound
isolated from the mushroom Amanita muscaria that stimulates
the parasympathetic nervous system and has been used to
treat various diseases such as glaucoma.
10. In 1890, John Jacob Abel became the first
pharmacology chair in the United States, at the
University of Michigan. He later went to Johns Hopkins
University in Baltimore. Abel was the first to isolate
the hormone epinephrine from the adrenal gland, isolate
histamine from the pituitary gland , and make pure
crystalline insulin.
Animals such as dogs, cats, pigeons, and frogs were
used to test pharmacological substances.
Humans were even used as test subjects.
Sometimes they suffered through severe adverse effects
from these substances, such as when the German
pharmacist Friedrich Serturner and three of his friends
had poisoning for several days from an alkaloid that
Serturner had isolated from opium. This alkaloid was
later named morphine, after the Ancient Greek god of
sleep, Morpheus
11. Rudolf Buchheim : was a German pharmacologist born
in Bautzen.
In 1845 he earned his doctorate from the University of
Leipzig and shortly after became an associate professor of
pharmacology, dietetics. history of medicine and medical
literature at the University of Dorpat.
In 1849 he was chosen as a full professor of pharmacology.
While at Dorpat he created the first pharmacological institute at
that school.
In 1867 he became professor of pharmacology
and toxicology at the University of Giessen.
12. Early , Pharmacologist focused on natural substances mainly plants
extract .
Pharmacology developed in 19th century as a biomedical science
that applied principals of scientific experimentation to therapeutical
contexts
Today Pharmacologists use genetics , molecular biology ,
biochemistry and other advanced tools to transform information
about molecular mechanisms and targets into therapies directed
against diseases , defects or pathogens and creates method for
preventive care , diagnostic and ultimately personalized medicines
