Term

Definition
A mutation that occurs in DNA that encodes for a certain protein, so you have 2 or more versions of the same protein
Term
How does polymorphism affect drug metabolism?
Definition
Can cause increase or decrease in speed of drug metabolism and excretion.
Term
What type of person have the majority of drug trials been performed on?
Definition

Term
What is a muscle spasm?
Definition
An involunatary contractions of muscles that are usually localized to a specific muscle group
Term
What is the goal of therapeutic treatment for muscle spasms?
Definition
To decrease discomfort, enhance mobility so pt can perform ADLs
Term
What is muscle spasticity?
Definition
A disorder of the CNS in which certain muscles continually receive a message to tighten and contract
Term
A patient has muscle spasm in his neck related to a recent stroke. Should he receive dantrolene (Dantrium) or cyclobenzaprine (Flexeril)?
Definition
Dantrolene (Dantrium)
Term
What is the difference between a centrally acting drug and a peripherally acting drug?
Definition
A centrally acting drug acts directly on the CNS while a peripherally acting drug does not and instead acts on a specific muscle/organ
Term
What is the difference between H1 receptor and H2 receptor?
Definition
H1 is related to smooth muscle of vascular system, respiratory passages, digestive tract; while H2 is related to the stomach
Term
What do the majority of NSAIDs inhibit?
Definition
COX1 receptors
Term
What are the 2 major drug classes used for nonspecific inflammation?
Definition
NSAIDs and corticosteroids
Term
Name the 3 major classes of NSAIDs
Definition
Saclicylates
Ibufrofen
Cyclooxygenase-2 (COX-2) inhibitors
Term
A 12-year-old girl has flu symptoms and is grabbing some medication from the medicine cabinet. What med should she avoid and why?
Definition
Acetylsalicylic Acid (Aspirin), because children under 19 can develop Reye's Syndrome
Term
Can a pregnant women in 3rd trimester take ibuprofen?
Definition
No, it is Pregnancy Category X for 3rd trimester
Term
Why do Aspirin and ibuprofen cause stomach problems?
Definition
Because they inhibit COX-1 and COX-2, which inhibits prostaglandins, which among other things, are responsible for mucus production along the stomach lining (in order to protect lining from gastric juices); so this makes the stomach more sensitive to gastric juices
Term
What is the antidote for acetaminophen overdose?
Definition
N-acetylcysteine (NAC) by mouth
Term
What is an immunostimulant and what is it primarily used for?
Definition
A drug that enhances ability of immune system to fight infection and disease. Used for cancer patients.
Term
What is an immunosuppressant and what is it primarily used for?
Definition
Drug that diminishes the body’s ability to fight infection and disease. Primarily used to prevent transplant rejection and dampen hyperactive immune responses.
Term
What are cytokines?
Definition
They are secreted by cells of immune system to help body mediate and intensify immune response
Term
What are interleukins?
Definition
They are a class of cytokines synthesized by lymphocytes, monocytes, macrophages, and other cells in response to antigen exposure
Term
True or false: Prednisone is a safe and effective drug for long term use of immunosuppression.
Definition
False. Prednisone, like all corticosteroids, is safe and effective short-term but can cause serious adverse effects long term
Term
What is active immunity?
Definition
When the body produces own antibodies in response to exposure
Term
What is passive immunity?
Definition
When preformed antibodies are transferred or donated from one person to another
Term
What are the 4 types of vaccines?
Definition
1. Attenuated vaccine
2. Inactive vaccine
3. Toxoid vaccine
4. Recumbinant technology vaccine
Term
Attenuated vaccine
Definition
Contain microbes capable of replicating and causing disease
• Very effective at producing immunity but are risky
• Instead use attenuated organisms (made less able to cause disease through application of heat and chemicals)
• Dangerous for immunosuppressed people
Term
Inactived vaccines
Definition
• 2 types: whole agent (dead microbes), subunit (specific segment of microb)
• Safer than live vaccines, but need boosters
Term
Toxoid vaccines
Definition
Bacterial toxins chemically modified to be incapable of producing disease
Term
Recombinant technology vaccines
Definition
Partial organisms or proteins generated in the laboratory
• Ex. Hep B
Term
Why can't immunosuppressed people take the spray form of the influenza vaccine?
Definition
Because that form contains the "live" virus
Term
What is the difference between a bacterial infection and a viral infection?
Definition
Bacteria are single-celled microorganisms that multiply on their own, while viruses require living hosts (such as your own cells) to multiply. Antibiotic drugs usually kill bacteria, but have no effect on viruses and you need antiviral meds.
Term

Term
What is the goal of asthma pharmacotherapy?

Term
What is an aerosol?
Definition
A suspension of minute liquid droplets or fine aerosol particles suspended in a gas
Term
What is the most common type of aerosol delivery device? How do most providers recommend it is used?
Definition
Metered-Dose inhaler, most providers recommend that it is used with a spacer
Term
What does a dry-powder inhaler (DPI) do?
Definition
It delivers the medication as a fine dry powder. Because the timing of drug delivery and inhalation does not have to be coordinated, more medication is delivered to the lung with a DPI.
Term
What is the class of drugs that are called rescue agents for asthma, and how do they work?
Definition
Beta2-adrenergic agonists. They activate the sympathetic nervous system, which relaxes bronchial smooth muscle, resulting in bronchodilation.
Term
What class of drugs are used for bronchospasm PREVENTION?
Definition
Inhaled Anticholinergics
Term
What is the most effective drug class for long-term control of asthma?
Definition
Inhaled Corticosteroids

Definition
Intranasal corticosteroids
Term

Definition
A drug that increases bronchial secretions; reduces thickness of bronchial secretions. Example= guaifenesin ( Mucinex
Term
What is a mucolytic?
Definition
A drug that directly loosens thick, viscous bronchial secretions. Example= Acetylcysteine (Mucomyst).
Term
What are the 3 classifications of skin disorders?
