Pharmacology Flashcards
Pharmacology
The study of the origin, uses, preparation, and effects of drugs on the body.
Genetic Engineering
When scientists manipulate chemical bonds and structures from microbes and the human genome.
What do pharmacokinetics, pharmacodynamics, and clinical trials have in common?
They build on biotechnology research, advancing pharmacology. With a basic knowledge of how drugs perform in the body and the effects they have on each of the body systems, a pharmacy technician can more effectively administer drug treatments to cure and treat diseases.
Pharmacodynamics
The branch of pharmacology that involves how a drug affects the body.
On what levels do the actions of drugs on the system occur?
Molecular or cellular
How many actions of drugs on the stem are there?
Seven (7)
Stimulating Action
The direct effects from a receptor agonist that stimulates the body.
Depressing Action
The direct effects from a receptor agonist that depresses the body.
Antagonizing Action
A drug binding to a receptor without activating it.
Stabilizing Action
A drug causing a neutral reaction, neither stimulating nor depressing the system.
Replacing Action
The accumulation of a substance in the system, such as glycogen stored as carbohydrates.
Direct Constructive Chemical Reaction
A drug producing beneficial results.
Direct Harmful Chemical Reaction
A drug causing cell destruction, which can be beneficial in situations such as cancer treatment.
Receptor
A protein molecule in a cellular membrane that can bind to a complementary molecule.
Agonist
A chemical capable of activating a receptor to generate a therapeutic response.
Partial Agonist
Only partially activates a receptor.
Enzymes
Proteins that are capable of producing chemical changes.
Transport Molecules
Molecules capable of transporting proteins from one cellular structure to another.
Ion Channels
Membrane proteins
Ligand
A substance that forms a complex with a molecule, binding to a hormone, to a neurotransmitter, or to neuromodulator receptors.
Affinity
The evolutionary relationship between a group of relative organisms–to develop drugs.
Efficacy
Creating a desired result or effect for most of the population though not all.
Therapeutic Window
Measures the dose required for the medication to be effective against the amount of it that would cause adverse side effects.
Duration of Action
How long the drug will be effective.
