Medical Administration Flashcards
FDA’s control over medication
Ensures that all medications on the market undergo vigorous testing before they are sold to the public
Define Chemical Name
Exact description of the medication’s composition and molecular structure
Define Generic Name
The adopted name given to the drug listed in official publication
Define Trade Name (Brand Name)
Name in which a manufacturer markets a medication
What are the three characteristics of Medication Classification
- The effect of the medication.
- Symptoms the medication relieves
- Medication’s desired effect
What does the form of medication determine?
The route of administration
What are the five factors that influence Drug Absorption
- Route of administration
- Ability of the medication to dissolve
- Blood flow to the site of administration
- Body Surface Area
- Lipid solubility of a medication
What is the most rapid form of medication absorption?
Intravenous
What does the ability of an oral medication to dissolve depend on?
it’s form of preparation
How does Body Surface Area relate to medication absorption?
The larger the surface area, the faster the medication is absorbed
How does lipid solubility relate to medication absorption?
Cell membranes have a lipid layer and allow lipid-soluble medications to cross over quickly
What two characteristics of medication affect the rate and extent in which medication is distributed?
- Physical properties
2. Chemical properties
What three factors affect the rate and extent of medication distribution in the body?
- Circulation
- Membrane Permeability
- Protein binding
Two forms of Parenteral Medication
- Solution
2. Powder
What is the primary organ for dug excretion?
Kidneys
What happens if renal function declines in regrades to medication excretion?
A patient would become at risk for medication toxicity
Define Therapeutic Effects
The expected or predicted physiological response or responses a medication causes
Define Side Effects
Predictable and often unavoidable secondary effects produced at a usual therapeutic dose
Define Adverse Effects
Unintended, undesirable, and often unpredictable severe response to medication
Define Toxic Effects
Developed after prolonged intake of a medication or when a medication accumulates in the blood stream because of impaired metabolism or excretion
Define Idiosyncratic Reactions
An unpredictable effect in which a patient overreacts or underreacts to a medication.
Define Allergic Reactions
Unpredictable responses to a medication. The medication or chemical acts as an antigen, triggering the release of the body’s antibodies
Define Medication Allergy
A severe or mild reaction where symptoms vary, depending on the individual and the medication
Define Anaphylactic Reaction
Severe or life threatening reaction that is characterized by sudden constriction of bronchiolar muscles
Define Medication Interaction
Altering the way another medication is absorbed, metabolized, or eliminated from the body
Define Synergistic Effect
Combined effect of two medications is greater than the effect if the medications were given separate
Define Serum Concentration
Amount of a drug compound in the body’s circulation
Define Peak Concentration
Highest serum concentration of the medication
Define Intravenous Infusion
Process of injected fluid or medication into the veins
Define Trough Concentration
minimum blood concentration or medication is reached just before the next scheduled dose
Define Onset Action
Time it takes after a medication is administered for it to produce a response
Define Peak Action
Medication reaches its highest effect
