Pharm C. 4, 5, 33, 34 Flashcards
What the body does to the drug (ADME)
Pharmacokinetic phase
During movement from administration into the systemic circulation
Absorption
Drug movement from the systemic circulation to the site of drug action
Distribution
Breaking down of drugs
Metabolism
Drug removal from the body
Elimination
Chemically converting a drug to a form that is more easily removed for. The body
Metabolism
Drug metabolized in the body, reducing concentration of drug available before it reaches systemic circulation
First pass effect
The amount of drug required to produce a therapeutic effect
Minimum effective concentration
Level that results in serious adverse effects
Toxic concentration
Plasma drug concentration between the minimum effective concentration and the toxic concentration
Therapeutic range
The amount of time to produce a therapeutic effect
Onset of drug action
When the medication has reached its highest concentration in the bloodstream
Peak plasma level
Amount of time a drug maintains its therapeutic effect
Duration of drug action
Higher amount of drug given 1 or 2 times to load the bloodstream with a sufficient level of drug. Given when therapeutic effects are needed quickly
Loading dose
Keeps the plasma drug concentration in the therapeutic range
Maintenance dose
What the drug does to the body
Pharmacodynamic phase
A drug that if more powerful will produce a therapeutic effect at a lower dose
Potency
A drug that produces the desired effect or intended result
Efficacy
A drug that produces the same type of response as the endogenous substance is called
Agonist
A drug that occupies a receptor and prevents the endogenous chemical from acting is called
Antagonist
Examines the role of heredity in drug response
Pharmacogenetics
Studies how all the genes can influence responses to drugs
Pharmacogenomics
A nonspecific defense system if the body where damaging chemicals and microorganisms can be neutralized
Inflammation
Cause vasodilation, relaxation of smooth muscle, increase capillary permeability, and sensitizes nerve cells to pain
Prostaglandins
