Pharmacology
|
|
This is any chemical substance that produces a biologic response in a living system. Used as a medicine to aid in diagnosis, treatment or prevention of disease.
|
drug
|
|
These are the processes that control the drugs:

|
|
highest potential for abuse/federal regulation

steady state concentration
|
|
For a steady state to be maintained the amount of drug in should equal the.....
|
the amount of drug out over a 24-hour period.
|
|
The number of times a medication is administered per day is dependent on the body clearance rate; if the body is unable to clear from system (excrete), continued dosing can result in ______
|
toxicity.
|
|
Describe factors that might influence medication’s action on a patient and provide a rationale for each.
|
Gender & Age
Hormonal differences Body weight Nutritional state Drug history Time of day Emotional or physiologic state |
|
This is an expected unintended effect that is essentially not harmful (benign)
|
side effect
|
|
This is an unintended effect that is harmful and unexpected
|
adverse effect
|
|
This is the effect of too much medication
|
toxic effect
|
|
This is the intended effect of the medication
|
Therapeutic effect
|
|
______is considered by the physician when prescribing medications.
It is important to weigh the possible effects against the desired outcome of the medication. For example: this drug kills cancer cells but it makes my hair fall out; this drug controls my blood pressure but I have a constant dry cough |
Risk vs Benifit
|
|
This describes the need for increasingly larger amounts to produce the desired effect
|
tolerance
|
|
This is a result of changes in the receptors over time and is NOT addiction
|
tolerance
|
|
This is the condition of being habitually or compulsively occupied with or involved in something.
|
addiction
|
|
Thias is the state of being enslaved to a habit or practice or to something that is psychologically or physically habit-forming, as narcotics, to such an extent that its cessation causes severe trauma.
|
addiciton
|
|

|
radionuclides
interventional agents contrast agents liable |
|
Drug Standards set by the federal government for drug safety:
|
1. Purity
2. Bioavailability 3. Potency 4. Efficacy 5. Safety and Toxicity |
|
This is the amount of drug is circulating in the bloodstream and/or ready to produce its intended action
|
Bioavailablity
|
|
_______ is affected by: binding capacity, lipid solubility/water solubility, and the drug’s ability to cross the blood brain barrier and/or the placental barrier.
|
Bioavailablity
|
|
This is a particular area that receives the maximum effect of a drug
|
Drug Receptor
|
|
This is tendency for a drug to attach to a particular site
|
Affinity
|
|
This is a drug that attaches to a receptor and produces an intrinsic activity
