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
