Pharmocodynamics
what drug does to the body mechanism by which the drug affects the body structure
Indications
Reason to use a particular drug for a particular disorder
Receptor
Target site for drug to act on during distribution
Therapeutic range
Blood concentration of a drug that produces the desired effect without toxicity
Toxicology
the branch of pharmacology that deals with the nature and effects and treatments of poisons
Drug
any substance, other than food, that causes a change in the structure or function of the body
Absorption
the process of absorbing nutrients into the body after digestion
Organ for Metabolism
Liver
Bioavailability
Measure of amount of drug that is actually absorbed from a given dose.
Tolerance
Drug stopsbworking as well after continuedbuse
Affinity
An attraction to receptor sight (specific response)
Five musts for a prescription
Name, route of administration,how much,when, dr name
Efficacy
Effectiveness in causing a response
Therapeutics
the branch of medicine concerned with the treatment of disease and suffering
Anaphalaxis
Life threatening allergy reaction
Five rights medication distribution
Drug,dose,patient,time,route
Hypersensitivity
Allergy to medication
distributions affected by what three things
Plasma,blood flow circulation,blood brainn barrier
Habituation
being abnormally tolerant to and dependent on something that is psychologically or physically habit-forming (especially alcohol or narcotic drugs)
Pharmacokinetics
the study of the movement of drugs and their metabolites through the body from absorption to excretion (basically, what the body does to the drug)
topical ways to give meds
skin creams,inhalations,transdermal
Three injection ways
Intramuscular,subcutaneous,intradermal
Tachyphylaxis
Rapid tolerance
Antagonist
Drugs with affinity for a receptor when combined littlenor no response
Potentiation
1+0=2 albuetrol plus maoi
Most important organ for excretion and metabolites
Kidneys
Side effect
a secondary and usually adverse effect of a drug or therapy
Pharmacotherapeutics
a major study in the realm of pharmacology concerned with how drugs are used in the treatment of disease within the human body
What four things effect excretion
Intestines,kidneys,skinnrespiration
Synergism
1+1=3 alcohol and drug give greater affect together
Name four enternal routes
Oral, sublingual,nasogastric,rectal
Additivity
1+1=2 Tylenol and motrin equal together equals separate
Four facts that affect absorption
Circulatory,solubility,Ph,particle size
Contraindicatioms
When drugbor treatment is not needed
Three effects of metabolism
Liver disease,liver enzyme,quantity of drug
Six factors that affect ADME
Age,weight,gender,route,disease,tolerance
Dependence
The need to take a substance to avoid physical discomfort
moa
Mechanism of Action
Agonoist
When drug bnds to receptor it causes a specific response
Onset drug action
Time it takes drug to work
