Studying pharmacology can seem overwhelming due to the vast array of drugs, their adverse effects, and mechanisms of action that you need to memorize. At times, it can feel like there's no rhyme or reason behind some of the facts you're expected to learn. And, many resources simply list information without providing the clinical reasoning that helps make connections for long-term memorization and practical application.
If you’ve ever grappled with these concerns, you’re not alone. In this blog, we’re diving headfirst into how to study pharmacology, unraveling its complexities, and shedding light on the importance of understanding this subject.
What is pharmacology?
Pharmacology is the branch of medicine that focuses on the study of drugs and their effects on the human body. It encompasses the understanding of drug composition, properties, interactions, and mechanisms of action. This field is essential for developing new medications and ensuring their safe and effective use in clinical practice.
What is the difference between pharmacokinetics and pharmacodynamics?
Pharmacokinetics describes what happens to an administered drug, including absorption, distribution, metabolism, and excretion. The term pharmacodynamics refers to the effects of a drug on the body; pharmacokinetics determines the onset, duration, and intensity of those effects. People often describe pharmacokinetics as “what the body does to a drug,” and pharmacodynamics as “what a drug does to the body.”
What do you learn in pharmacology?
In pharmacology, students learn about various drug classes, their mechanisms of action, therapeutic uses, side effects, and interactions with other drugs.
To give you a sense of the scope, let’s look at the 2021 USMLE® outline for pharmacodynamic and pharmacokinetic processes: general principles. Though this is the past version of the content outline, it gives an overview of the foundational knowledge needed that encompasses each individual section of the 2024 USMLE® outline.
- Pharmacodynamic and pharmacokinetic processes: general principles
- Pharmacokinetics: absorption, distribution, metabolism, excretion, dosage intervals
- Mechanisms of drug action, structure-activity relationships (eg, anticancer drugs)
- Concentration and dose-effect relationships (eg, efficacy, potency), types of agonists (eg,
full, partial, inverse) and antagonists and their actions - Individual factors altering pharmacokinetics and pharmacodynamics (eg, age, gender,
disease, tolerance, compliance, body weight, metabolic proficiency,
pharmacogenetics) - Mechanisms of drug adverse effects, overdosage, toxicology
- Mechanisms of drug interactions
- Signal transduction, including structure/function of all components of signal transduction
pathways such as receptors
What percentage of the Step 1 Exam is pharmacology?
While we’ll never know the exact number of Step 1 pharmacology questions that will pop-up on your exam, we can look to the content outline to discover the topics and their percentage weight. This way, you can focus your studies to coincide with the percentage weights of the topics.
According to the Step 1 Content Outline and Specifications from the USMLE®, under Step 1 Discipline Specifications, pharmacology has a range of 15-22%.

What percentage of the Step 2 Exam is pharmacology?
According to the Step 2 CK Content Outline and Specifications from the USMLE®, under Step 2 CK Physician Tasks/Competencies Specifications, pharmacotherapy has a range of 8-12%.

Did you know?
MedStudy's Medical Student Core Pharmacology book is written by expert physician educators based on the USMLE Step 1 & 2 Content Outlines.
When you study with MedStudy resources, you know that what you're studying is already based on the weighted percentages of each topic.
Is pharmacology hard?
Pharmacology can be challenging due to the vast amount of information and the need to understand complex biochemical pathways and drug interactions. Though it might feel overwhelming at times, with the right approach and study techniques, it becomes manageable and even rewarding!
Why is pharmacology important?
For medical students, pharmacology is crucial because it forms the basis for how you will use and prescribe medications for your future patients. Understanding pharmacology helps medical professionals prescribe the right drugs at the right dosages, manage side effects, and avoid harmful drug interactions. The study of pharmacology is also important for the development of new therapies and advancing medical research.
How to study for pharmacology in med school
Studying pharmacology effectively requires a strategic approach and the right resources. Here are some tips to help you excel in this subject:
Find the right resources
For this part, using the Pharmacology Medical Student Core book and pharmacology questions from the the Step 1 & Step 2 Qbank+ is going to be essential. Let's break down why these are going to be your best resources to use.
Use this pharmacology textbook as a study aid
The Pharmacology Core book breaks down only what you need to know for foundational knowledge in medical school and the USMLE® exams. You won't be bogged down by the extra fluff used in some pharmacology textbooks.
Check it out for yourself!
Get a comprehensive overview of pharmacology
Start with the Pharmacology Medical Student Core book for a broad overview of pharmacology to understand the basic concepts and framework. This will help you contextualize detailed information as you progress through your studies. Utilize the book's 40 summary charts, diagrams, and figures to reinforce your understanding.
Because there is so much to memorize in pharmacology, the topic requires a strategic study approach. Begin by understanding the fundamental concepts like pharmacokinetics and pharmacodynamics and drug development and then dive into the specific drugs used for each subtopic.
Try to get the basics down pat before moving on. This foundational knowledge will serve as your anchor as you delve deeper into the subject. Our pharmacology textbook “chunks” up the information by topic, and then by subtopic, to make it easier for you to learn and memorize.

Use pharmacology questions to study
To accompany your study of pharmacology from the Core book, you'll find the Step 1 & Step 2 Qbank+ essential for testing yourself on what you're learning. With 88 questions pertaining to pharmacology in our Step 1 Qbank+ and 40 in our Step 2 Qbank+ you can self-test and pinpoint your knowledge gaps.
Use pharmacology patient cases to study
Why did you choose to study medicine? Most students would probably say to help people. The best way to keep your mind focused on your why is to imagine yourself in your role as a physician helping patients. And, the best way to do that is by answering Qbank+ questions.
Try it out with this Step 1 Qbank+ question. Imagine yourself in the exam room with this patient, how would you answer?

Did you know?
When Qbank+ is purchased with digital Core, the content is interlinked. Meaning, you can easily move from questions in your Qbank+ to the same topic in the digital Core for deeper learning. And vice versa.
And, in the Medical Student Core, there are Clinical Pearls pulled out from the content and highlighted for you, so you can imagine yourself in patient scenarios like the one below. Clinical Pearls offer a unique way to visualize why what you’re learning in pharmacology will be important to your future patients!
