Study Notes

Introduction to Pharmacology

Pharmacology is the study of drugs and their effects on life processes, including activation or inhibition of normal body processes, therapeutic effects, side/adverse effects, and toxic effects.

History of Pharmacology

Pharmacology emerged as a fundamental science in modern medicine, enabling the rational use of effective agents in the diagnosis and treatment of disease.
The goal of pharmacology is to understand the mechanisms by which drugs interact with biologic systems.
The discipline of pharmacology drives the international pharmaceutical industry to billion-dollar profits.
The word "pharmacology" comes from the Greek word "pharmakon," meaning remedy or drug.

Definition of Drugs

A drug is any article recognized in official pharmacopeia or any official compendium.
A drug is any article intended for use in the diagnosis, cure, mitigation, treatment, or prevention of diseases in man and animals.
A drug is any article, other than food, intended to affect the structure or any function of the human body or animal.
Herbal or traditional drugs are also considered drugs.

Classification of Drugs

Drugs may be hormones, neurotransmitters, or peptides produced by the body.
Drugs may be xenobiotic, produced outside the body, either synthetic or natural.
Poisons are drugs that can kill.
Toxins are drugs that can kill and are produced by a living organism.

Sources of Drugs

Natural sources of drugs include plants, microorganisms, animal tissues, and minerals.
Synthetic drugs are created through the synthesis of new compounds and modifying existing drugs.

Drug Names

Drugs have three types of names: chemical name, generic name (non-proprietary name), and brand name (proprietary name).

Divisions of Pharmacology

Toxicology is the study of poisons and organ toxicity, focusing on the harmful effects of drugs and other chemicals.
Pharmacotherapeutics is the medical science concerned with the use of drugs in the treatment of diseases.
Pharmacy is the science and profession concerned with the preparation, storage, dispensing, and proper use of drug products.
Pharmacognosy is the study of drugs isolated from natural sources.
Medicinal chemistry is the branch of organic chemistry that specializes in the design and chemical synthesis of drugs.
Pharmaceutics is concerned with the formulation and chemical properties of pharmaceutical products.

Quotes

"All substances are poisons; there is none which is not a poison. The right dose differentiates a poison and a remedy." - Paracelsus
