A self-study guide for graduate students in Pharmacology at the University of Toronto. It provides a list of core principles of pharmacology that all students should master, regardless of their academic background. The document also outlines resources that students can use to achieve a solid understanding of these principles, including courses offered at the undergraduate level and a recommended textbook. Students' mastery of the principles will be evaluated through exams and other assessments throughout the M.Sc. and Ph.D. programs.

CORE PRINCIPLES OF PHARMACOLOGY:
A SELF-STUDY GUIDE FOR GRADUATE STUDENTS
Rationale for this document.
Students admitted to the M.Sc. and Ph.D. programs in Pharmacology at the
University of Toronto come from diverse academic backgrounds. While all our incoming graduate
students normally have solid background preparation in biochemistry and physiology, the amount of
exposure to pharmacology that students have had at the undergraduate level varies considerably.
Regardless of academic background, it is essential that ALL Pharmacology graduate students achieve a
solid understanding of the core principles of pharmacology. This document has been prepared to assist
students with achieving this goal.
How to make use of this document.
During the first year in the Pharmacology graduate program,
normally while taking the Graduate Pharmacology PCL1002Y course, students should conduct a self-
assessment of their mastery of the core principles of pharmacology listed in this document. During the
first year and on an on-going basis throughout the program, students should undertake self-directed study
as needed to achieve a solid understanding of these principles. The resources outlined in this document
should help students accomplish this essential task.
How mastery of the principles will be evaluated.
A primary opportunity to evaluate students’
knowledge of pharmacological principles arises in the Graduate Pharmacology PCL1002Y course.
Students are expected to display a solid understanding of these principles in the oral presentations of
research paper critiques, in the grant-writing exercise, and especially on the exams in this course. Each
exam in PCL1002Y will test knowledge of course content as well as basic principles. Beyond this course,
there are multiple opportunities for the evaluation of students’ mastery of the core principles throughout
the M.Sc. and Ph.D. programs.
Resources to be used in concert with this document.
To assist you with mastering the basic principles
of our discipline, you are also welcome (although not required) to make use of various courses offered at
the undergraduate level. The courses that are particularly relevant with respect to basic principles of
pharmacology and toxicology are the following:
• PCL201H: Introduction to Pharmacology and Pharmacokinetic Principles
• PCL302H: Pharmacodynamic Principles
• PCL362H: Introductory Toxicology
• PCL469H/470H: Systems Pharmacology I & II (graduate equivalent is PCL1001Y)
If you wish to attend lectures in these courses and/or access the on-line course materials, please contact
the relevant course coordinators for permission.
The catalogue of core principles below includes a listing of relevant chapters from our currently
recommended textbook, the 15th edition of Katzung’s “Basic & Clinical Pharmacology”. Studying these
chapters will assist you in mastering the material. This book is generally available in the University of
Toronto Bookstore and in the University of Toronto Library system (books and/or electronic online
resources). It can also be purchased from several online retailers. The full bibliographic information for
this book is as follows:
Basic & Clinical Pharmacology, 15th Edition. Edited by BG Katzung & TW Vanderah. McGraw-Hill,
New York (2021). ISBN: 978-1-260-45231-0

1. Principles of Pharmacokinetics & Toxicokinetics (a) Absorption [Chapters 1 & 3] - routes of drug administration and factors that influence choice - mechanisms of drug movement across biological membranes and factors that influence drug solubility and membrane permeability - factors that influence drug bioavailability (b) Distribution [Chapters 1 & 3] - the volume of distribution and its relationship to physiological body volumes - factors influencing drug binding to plasma proteins and tissue reservoirs (c) Biotransformation / Metabolism [Chapter 4] - relationship of drug metabolism to excretion of drugs and termination of drug effects - metabolism as a determinant of bioavailability: the first-pass effect - pathways of drug metabolism: phase I (oxidation, reduction, hydrolysis) and phase II (glucuronidation, sulfation, acetylation, methylation, glutathione conjugation) - enzyme multiplicity and broad substrate selectivity of drug-metabolizing enzymes, with the cytochromes P450 as a prime example - role of drug metabolism in adverse drug reactions: factors that control the balance between drug bioactivation and detoxification - drug-metabolizing enzymes as key sites for drug-drug interactions: inhibition and induction of drug metabolism (d) Excretion [Chapters 1 & 3] - major sites of drug elimination: liver and biliary excretion, kidney, lungs - factors influencing hepatic and renal clearance of drugs (e) Mathematical Analysis of the Time-Course of Drug Action [Chapter 3] - relationship between dose, plasma drug concentration and effect - plasma concentration-time curves following oral drug administration: absorption, distribution and elimination phases - definitions and mathematical relationships among the following terms: volume of distribution, half-life, clearance, bioavailability, area under the concentration-time curve - pseudo-zero-order and first-order kinetics of drug elimination - rational dosing to achieve a target steady-state drug concentration: loading dose and maintenance dose 2. Principles of Pharmacodynamics & Toxicodynamics (a) Quantitation of Drug-Receptor Interactions [Chapters 1 & 2] - nature and properties of biological drug receptors - definitions and mathematical relationships among the following terms: equilibrium dissociation constant, total number of specific receptor binding sites - receptor saturation: the simple hyperbolic relationship between drug concentration and the concentration of drug-receptor complex, and the mathematical analysis that is analogous to the Michaelis-Menten treatment of enzyme-substrate interactions - chemical determinants of selectivity in drug-receptor interactions (b) Quantitative Relationship Between Receptor Occupancy and Effect [Chapters 1 & 2] - the relationship between drug concentration or dose and the biological effect, as defined by the log-dose-response curve - analysis of log-dose-response curves to gain understanding of the following drug properties: median effective concentration or dose, median lethal concentration or dose, therapeutic index,

5. Drug Development and Regulation [Chapter 1] - approaches for the discovery and development of new drugs - preclinical testing of new drugs: in vitro and in vivo animal studies required to bring a new chemical entity to the stage of clinical investigation - clinical trials: the phases of clinical testing of new drugs; factors to consider in the design of clinical trials; ethical issues - post-marketing surveillance of drugs; adverse drug reaction reporting - drug regulatory systems with the FDA in the United States as an example - sources of unbiased information about the clinical uses of drugs, e.g. “The Medical Letter on Drugs and Therapeutics”, etc.
