This lesson covers therapeutic equivalence, it's definition, it's implications, and examples. The examples include prescription and non-prescription examples. Additionally, it touches on how some prescription medications are known by the public. Personal choice, as well as physician choice regarding medication option is briefly covered.

Reading & Interpreting Pharmacological Information

4. Reading & Interpreting Pharmacological Information

It can be difficult interpreting the jargon on your prescription drugs, but in this lesson we'll outline what to look for and where you can go to find more information. This will keep you healthy and happy.

What is a Mechanism of Action?

5. What is a Mechanism of Action?

How much thought have you given to exactly what happens once you swallow a pill, inhale a medicine or get an injection? We are going to learn what a mechanism of action is and discuss a few of the many mechanisms of action that exist.

The First Pass Effect in Pharmacology

6. The First Pass Effect in Pharmacology

Did you know that when you take a pill, only a fraction of that pill actually makes it into general circulation? Do you know why this is so? It has something to do with the first pass effect.

Mnemonics for Pharmacological Terminology

7. Mnemonics for Pharmacological Terminology

There are helpful aides to studying the various types, indications, side effects and contraindications of various drugs. In this lesson, explore some common mnemonics of the pharmacological world including IDEA, DR. TIMED, LEAN, and more!

What is ADME? - Definition & Process

8. What is ADME? - Definition & Process

Have you ever wondered what happens to the drug you take once you have taken it? That's what ADME and pharmacokinetics is all about! Don't be intimidated. Like swallowing a small vitamin pill, this lesson isn't all that hard.
