Introductory Pharmacology

PHAR 100/3.0

Topics covered include central nervous system stimulants and depressants, narcotics, alcohol, cardiovascular agents, contraceptives, environmental toxicants, mechanism of drug action and disposition, antibiotics, drugs used in sports, over-the-counter drugs, food additives, and vitamins.


This course is designed as an introduction to pharmacology and toxicology. Pharmacology is broadly defined as the effect of drugs and chemicals on living organisms. Toxicology is closely related to pharmacology and is the study of the deleterious effects of drugs and chemicals on living organisms. Pharmacology and toxicology courses are usually taught following courses in physiology and biochemistry. Pharmacology 100/3.0 is designed as a general interest introduction to pharmacology and the knowledge of physiology that is required to understand drug action is included in the textbook and the notes. The course is based on a similar course that has been offered at Queen's for the past 30 years.
