Introduction to Pharmacology & Medical Math
By: Cindy Quisenberry
Pharmacology - the study of drugs and their origin, nature, properties, and effects on living organisms. We need to know why drugs are given, how
they work, and what effects to expect.
ClassificationEach drug can be categorized under a broad
subcategory or subcategory. While drugs can be classified several
different ways, grouping them together according to their therapeutic use is most helpful to the healthcare professional.
Drugs that affect the body in similar ways are listed in the same classification. Drugs that have several types of therapeutic effects fit under several classifications.
Generic Name – common or general name assigned to the drug by the United States Adopted Name (USAN) Council; differentiated from the trade name usually by initial lowercase letter
Trade Name – The name by which a pharmaceutical company identifies its product; is copyrighted and used exclusively by that company; can be distinguished from the generic name by capitalized first letter and is often shown on labels and references with the symbol after the name (for “registered” trademark)

Pharmacotherapeutics – the study of the effects of drugs and examine the mechanism of action, describes the effects produced by a drug, determines what dose of a drug is needed to produce the desired effect, determines what dose a drug produces toxic effects.
