Pharmacokinetics
The process of drugs entering the body into the bloodstream?
Absorption
The process where the drug is distributed or dispersed throughout the body?
Distribution
The process where the drug is broken down by the body, usually in the GI tract?
Metabolism
After metabolism, the drug is eliminated from the body?
Excretion
What is the study of the biochemical and physiological effects of drugs on the body?
Pharmacodynamics
For drugs to affect the body they have to reach their target cells or tissues. They do this by interacting with what?
Receptors
What are receptors?
Proteins located inside the cells or on the cell surface.
What mimics normal physiological processes in the body?
Agonist Drug Molecules
What happens when a agonist drug molecule binds to a receptor?
It activates the receptor and generates a response.
What are designed to inhibit or block an agonists from activating a receptor?
Antagonist drug molecule
What are brain chemicals that send messages to the body by binding with specific receptors?

A reason to use a certain treatment?
Indication

Contraindication
What occurs when two or more drugs react with each other?
Drug-drug interactions
The combined effect of two drugs is equal to the sum of the effects of each drug taken alone?
Addition
The action of one drug antagonizes the action of another drug?
Antagonism
One drug enhances or prolongs the effects of another drug?
Potentiation
The combined effect of two drugs is greater than the sum of the effects of two drugs?
Synergism
Occurs when a drug that is intended for therapeutic use cause certain harmful effects because of a disease or pre-existing condition that the patient has?
Drug-disease interactions
When certain foods or beverages increase or decrease the effects of drugs in the body?
Drug-nutrient interactions
Occurs when herbal or dietary supplements increase or decrease a drugs effects?
