Cards

Term

Definition
The study of medicines
Term

PHARMACOLOGIC CLASSIFICATION
Definition
How the drug does what it does
Term
WHAT IS A PROTOTYPE DRUG?
Definition
Those drugs in a class that often demonstrate the most common characteristics of that class, most common therapeutic responses and adverse reactions

FDA
Term

Term
WHAT IS THE DIFFERENCE BETWEEN THE FDA REGULATION OF MEDICINES VERSUS REGULATION OF HERBAL SUPPLEMENTS?
Definition
Herbal supplements are regulated as food by the FDA and therefore are not studied with the same rigor.
Term
WHAT ARE SCHEDULED DRUGS?
Definition
Drugs that can cause dependence.
Term
HOW ARE SCHEDULED DRUGS RANKED AND WHICH ARE THE MOST COMMONLY PRESCRIBED?
Definition
Ranked 1-5 with 1 having the highes potential for dependence and 5 having the lowest potential for dependence. Schedule II drugs are most commonly prescribed.
Term
WHAT ARE THE REGULATIONS FOR "WASTING A DRUG?"
Definition
2 licensed professionals must sign off saying that the drug was disposed of properly.
Term
WHAT ARE SOME COMMON ROUTES FOR MEDICATIONS?
Definition
Oral; IV; IM; Sublingual; Buccal; Topical; Rectal; Vaginal
Term
WHY DO DRUGS THAT ARE ENTERIC, COATED, OR XR NEED SPECIAL CONSIDERATIONS WHEN ADMINISTERING THEM?
Definition
Because these drugs have to be administered a particular way or the patient will not be receiving the appropriate dose.
Term
WHAT IS PHARMACOKINETICS?
Definition
How the body handles a drug
Term
WHAT IS THE GOAL OF PHARMACOKINETICS?
Definition
The goal is for the drug to reach the target cells
Term
WHAT IS DIFFUSION/PASSIVE TRANSPORT?
Definition
When a medications passes from an area of higher concentration to an area of lower concentration
Term
WHAT DOES ADME STAND FOR?
Definition
Absorption, Distribution, Metabolism, Excretion
Term
WHAT SYSTEM/ORGAN DO WE THINK ABOUT WHEN TALKING ABOUT ABSORPTION?
Definition
We think about the ROUTE of administration so any systems/organs related to that (ex: Oral=GI=Onset time of 30-90 minutes)
Term
WHAT SYSTEM/ORGAN DO WE THINK ABOUT WHEN TALKING ABOUT DISTRIBUTION?
Definition
We think about blood flow and we also think about BARRIERS to distribution, such as the Blood-Brain barrier.
Term
WHAT IS DISTRIBUTION?
Definition
The continued movement of medication after absorption
Term
WHAT ORGAN SHOULD WE THINK ABOUT WHEN WE TALK ABOUT METABOLISM?
Definition
Liver
Term
WHAT IS THE FIRST PASS EFFECT?
Definition
Mechanism whereby drugs are absorbed, enter into the hepatic portal circulation, and are inactivated by the liver before they reach general circulation
Term
HOW ARE THE DOSAGE STRENGTH OF ORAL MEDICATION AND THE FIRST PASS EFFECT RELATED?
Definition
The first pass effect might inactivate the majority of a drug, so this is one reason that oral doses of a certain medication are higher than the same med dose in a different route
Term
WHAT ORGAN/SYSTEM SHOULD WE THINK OF WHEN WE TALK ABOUT EXCRETION?
Definition
The urinary system, particularly the kidneys (but not always of course, such as asthma patients using inhalers)
Term
WHAT IS A THERAPEUTIC RANGE?
Definition
Dosage that produces the desired effects of a drug. NOTE: Think toxicity, for this range does not always correlate to a clinical response in a patient
Term
WHAT IS CYP?
Definition
An enzyme (P450) that metabolizes drugs as well as nutrients. Although the liver is the major site for CYP activity, nearly every tissue in the body has some CYP enzymes
Term
WHAT ARE ISOZYMES?
Definition
Different forms of cytochrome P450 the perform slightly different metabolic functions
Term
WOULD YOU EVER RAISE THE DOSE OF A MEDICATION IF THE BLOOD LEVEL IS WITHIN THERAPEUTIC RANGE?
Definition
Yes, if the patient states that they are not feeling any effects, you may raise the dose level even if blood levels are already within range (ex: Lithium)
Term
WHAT IS PLASMA HALF-LIFE?
Definition
Time required for plasma concentration to decrease by one-half
Term
WHAT IS A "LOADING DOSE?"
Definition
A higher amount of drug, often given only once or twice, that is administered to "prime" the bloodstream with a level sufficient to quickly induce a therapeutic response.
Term
WHAT IS A "MAINTENANCE DOSE?"
Definition
Given to keep the plasma drug concentration in the therapeutic range
Term
WHAT IS PHARMACODYNAMICS?
Definition
How drugs act on the body
Term
WHAT IS "THERAPEUTIC INDEX?"
Definition
The ratio of a drug's LD50 (median lethal dose) to its ED50 (median effective dose). Thus, the therapeutic index (TI) is a measure of a drug's safety margin: the higher the value the safer the medication
Term
WHAT IS THE MARGIN OF SAFETY?
Definition
MOS is another index of a drug's effectiveness and safety-it's calculated as the amount of drug lethal to 1% of animals divided by amount that produces therapeutic effect in 99% of animals. Higher MOS=safer med
Term
WHAT IS POTENCY?
Definition
The strength of a drug at a specified concentration or dose
Term
WHAT IS EFFICACY?
Definition
The greatest maximal response that can be produced from a particular drug
Term
WHAT IS THE RECEPTOR THEORY?
Definition
Predicts that the response of a drug is proportional to the concentration of receptors that are bound or occupied by the drug
Term
WHY ARE NURSES IMPORTANT IN RELATION TO ADVERSE DRUG EFFECTS?
Definition
Nurses are the last cross-check of safety before patient takes drug
Term
WHAT ARE ADVERSE DRUG EFFECTS?
Definition
Things we hope to avoid and monitor for carefully
Term
WHAT ARE SIDE EFFECTS?
Definition
More expected events as a result of a certain medication
Term
WHAT IS A BLACKBOX WARNING?
Definition
This label on a medication happens after medication has been approved - as drug is prescribed to more ppl there can be negative effects not seen previously. These warnings are shared with patient but don't preclude prescribing
Term
WHAT IS AN IDIOSYNCRATIC RESPONSE?
Definition
An adverse drug effet that produces an unusual and unexpected response that is not related to pharmarcologic action of drug. Not classified as allergies because they are not immune related.
Term
LIST SOME TYPES OF ORGAN SPECIFIC TOXICITY
Definition
Nephrotoxicity, Neurotoxicity, Hepatotoxicity, Dermatologic Toxicity, Bone Marrow Toxicity, Cardiotoxicity, Skeletal Muscle Toxicity
Term
WHAT ARE THE "5 RIGHTS" RELATED TO REDUCING RISK?
Definition

1. Right Dose

2. Right Medication

3. Right Patient

4. Right Route

5. Right Time

Term
WHAT IS MEDICATION RECONCILIATION?
Definition
A process of keeping track of a patient's medications as their care proceeds from one health care provider to another
Term
WHAT ARE THE STEPS OF THE NURSING PROCESS?
Definition
Assessment, Nursing Diagnosis, Plan, Implementation, and Evaluation
Term
WHAT IS IMPORTANT TO DO AFTER EACH STEP OF THE NURSING PROCESS?
Definition
Reassess
Term
WHAT IS PAIN?
Definition
Whatever the patient says it is
Term
WHAT IS THE GOAL OF PAIN MANAGEMENT?
Definition
For pain to be managed-it might not be realistic for a patient to have a pain level of 0/10
Term
WHEN DO PROVIDERS CONSIDER ADMINISTERING OPIOIDS?
Definition
They are usually reserved for moderate to severe pain
Term
WHAT IS THE DIFFERENCE BETWEEN OPIOIDS AND NARCOTICS?
Definition
They are often used interchangeably, but narcotics covers a broader scope of meds
Term
