Module 3: Drug Categories of Relevance to Radiography Flashcards
is the study of drug actions and drug interactions with living organisms
Pharmacology
chemical substances that are not required for normal maintenance of body function and produce a biologic effect in an organism
Drugs
The study of the way the body processes a drug & includes how drugs are absorbed, reach their site of action, are metabolized (physically & chemically changed), and exit the body
Pharmacokinetics
ADME in Pharmacokinetics
- Administration
- Distribution
- Metabolism
- Excretion
the effects of drugs on the normal physiological functions of the body
Pharmacodynamics
most common mechanism of drug action
drug binding to the receptor sites on a cell
A drug that binds to the receptor, producing a similar response to the intended chemical and receptor , A drug that promotes the desired result
Agonists
blocks receptor site of histamine cell thus reducing itching and swelling
Antihistamine
A drug that attaches itself to the receptor, preventing the agonist from acting.
A drug that stops the receptor from producing a response
Antagonist

- Vasodilators and Vasoconstrictors
Drugs that relieve pain without causing loss of consciousness
Analgesics
What are the two groups Analgesics can be divided on
- Nonopioids (nonnarcotic)
- Opioids (narcotic)
Reversibly depress neuronal function producing loss of ability to perceive pain and/or other sensations
Anesthetic Agents
General anesthetics
Halothane
General anesthetics
- Inhalation agent
