Central Nervous System Pharmacology

1. Central Nervous System Pharmacology

The most important parts of your body are related to the central nervous system, but they can suffer from various disorders. Learn what this system is and a bit about the disorders it may have, as well as the pharmacology behind treatment for these disorders.

Autonomic Nervous System Pharmacology

2. Autonomic Nervous System Pharmacology

Like the dishwasher automatically washes your dishes, your brain automatically does things for you as well. Find out how this is so and how medications can influence the systems responsible.

Pharmacology of the Endocrine System

3. Pharmacology of the Endocrine System

Your body would cease to function without the endocrine system. This lesson describes what this system is as well as examples of the pharmacology related to it.

Pharmacology of the Cardiovascular System

4. Pharmacology of the Cardiovascular System

A healthy cardiovascular system is essential to overall health and wellness. This lesson outlines some of the most common cardiovascular disorders and the medications used to manage them.

Respiratory System Pharmacology

5. Respiratory System Pharmacology

The respiratory system is a highly dynamic and complex collection of organs. This lesson serves to introduce some basic concepts related to disorders affecting this system and potential therapeutic measures thereof.

Adrenergic System: Definition, Stimulation & Effects

6. Adrenergic System: Definition, Stimulation & Effects

The adrenergic system involves a lot of nerves, hormones, neurotransmitters, tissues, and organs. Learn about the important fundamentals behind this system and what it does.

Ocular Pharmacology & Pharmacokinetics

7. Ocular Pharmacology & Pharmacokinetics

The human eye is a complex structure and requires complex medications to treat conditions. In this lesson, we will learn about ocular medications and the pharmacology of them.

Ocular Drug Delivery Systems & Medications

8. Ocular Drug Delivery Systems & Medications

This lesson goes over several ways by which drugs can be delivered to the eye, including topically, systemically, intravitreally, and intracamerally. You'll then learn the names and purposes of several of these drugs.

Geriatric Pharmacology & Pharmacotherapy

9. Geriatric Pharmacology & Pharmacotherapy

Have you ever wondered what changes occur in our body as we age, and how those changes translate to the use of medications? This lesson goes over a wide variety of such changes and their effects.

Receptors in Pharmacology

10. Receptors in Pharmacology

This lesson will explain the fundamental nature of how drugs exert their effects on the body, if the same drug can have different effects on the body, and why side effects occur in the context of this all.

Routes of Drug Administration: Oral, Topical, Inhalation & Injection

11. Routes of Drug Administration: Oral, Topical, Inhalation & Injection

The way by which illicit drugs can be administered or taken into the body are numerous. These routes include the oral route, transdermal, inhalation, and intravenous injection.

Physiological vs. Psychological Drug Tolerance

12. Physiological vs. Psychological Drug Tolerance

In this lesson, we are going to look at physiological as well as psychological drug tolerance. We will cover how these two types of drug tolerance develop and go over the similarities and differences.

Pharmacokinetic vs. Pharmacodynamic Tolerance

13. Pharmacokinetic vs. Pharmacodynamic Tolerance

We are going to look at what is happening in the body when we notice the development of drug tolerance. This lesson is going to discuss pharmacokinetic and pharmacodynamic tolerances as well as their similarities and differences.

Glucagon vs. Insulin: Functions & Feedback Loop

14. Glucagon vs. Insulin: Functions & Feedback Loop

Have you ever wondered how sugar from your food gets into your cells? In this lesson, we'll be learning about how two hormones, insulin and glucagon, work together to regulate your blood sugar levels to keep your cells working properly.

Melatonin Supplements: Definition, Uses & Side Effects

15. Melatonin Supplements: Definition, Uses & Side Effects

Feeling tired? Well, it's probably because your melatonin levels are rising, but that's not the case for everyone! In this lesson learn all about the uses for melatonin supplementation, and the side effects such supplementation can prompt.

Melatonin Mechanism of Action

16. Melatonin Mechanism of Action

Melatonin is a supplement that can help with insomnia without side effects like sleeping pills have. In this lesson we will learn about how melatonin works.

What is Depyrogenation? - Definition & Methods

17. What is Depyrogenation? - Definition & Methods

This lesson explains to you something known as pyrexia, pyrogens, and depyrogenation. Then you'll learn about the main method of depyrogenation as well as some alternative ones as well.
