What are some (8) therapeutic effects for drugs with ADRENERGIC EFFECTS (alpha, b1, b2 agonists)?
|
|
|
drugs w/adrenergic effects (alpha, b1, b2 agonists)
|
usually cardiovascular (alpha or b1) or bronchiolar(b2) effects desired. Target may also be metabolic rate (b2).
|
|
|
allergic reactions
|
a. can reverse bronchiolar constriction (b1)
b. can cause vasoconstriction and reduce edema (alpha) c. can increase cardiac output (b1) |
|
|
(b2)
|
What adrenergic drug can reverse bronchiolar constriction with allergic reactions?
|
|
|
(alpha)
|
What adrenergic drug can cause vasoconstriction and reduce edema with allergic reactions?
|
|
|
b1
|
What adrenergic drug can increase cardiac output with allergic reactions?
|
|
|
a. can reverse bronchiolar constriction (b1)
b. can cause vasoconstriction and reduce edema (alpha) c. can increase cardiac output (b1) |
With adrenergic (agonist) drugs, what do they do therapeutically, to reverse allergic reactions?
|
|
|
Chronic obstructive pulmonary disease
|
asthma
emphysema chronic bronchitis inhalation causes fewer side effects than oral or sublingual routes |
|
|
Prolonged
microclots necrosis vasodilator |
________ shock (beta). Note: already getting reflexive sympathetic discharge. Too much vasoconstriction reduces circulating plasma volume and causes _______ contributing to shock. Body needs are not being met and some ________ is likely; therefor, use _________ (b agonists)
|
|
|
Isoproterenol
Dopamine |
What are some examples of drugs that are B agonists and vasodilate blood vessels when in prolonged shock?
|
|
|
Hypotension
|
like that caused in spinal anesthesia (alpha). Not the same thing as shock. In ____________, the fluids remain inside blood vessels (not in tissue spaces) and, with effort, body needs are being met.
|
|
|
Nasal congestion
|
use as nose spray
fewer side effects (alpha) |
|
|
local anesthetics
|
delay absorption (longer acting with fewer central side effects (alpha).
|
|
|
Topical hemostatic
|
alpha
dentist professional sports nosebleeds controls bleeding |
|
|
alpha agonists
|
Which adrenergic drug dilates pupil for an eye exam?
|
|
|
dilates
|
In the sympathetic nervous system, the pupil constricts or dilates?
|
|
|
constricts
|
In the parasympathetic nervous system, the pupil constricts or dilates?
|
|
|
1. anxiety, tremulousness (CNS effect)
2. awareness of rapid heart beat |
What are some side effects of taking drugs w/ adrenergic effects (agonists)?
|
|
|
photophobia
headache substernal pain (heart pain) serious arrythmias (b1) fatal cases have acute pulmonary edema (increased BP causes heart failure) (alpha) |
What are some toxic effects or untoward effects for taking drugs w/ adrenergic effects (agonists)?
|
|
|
drugs w/ adrenergic effects (agonists)
|
fatal cases have acute pulmonary edema (increased BP causes heart failure) (alpha)
|
|
|
tissue necrosis
|
What is the local toxicity for taking drugs w/ adrenergic effects (agonists)?
|
|
|
tissue necrosis
|
i.e. if infused into the vein with insufficient blood flow
|
|
|
1. Angina
2. Hypertension 3. Hyperthyroidism |
What are some contraindications or reasons why you wouldn't want to take adrenergic agonist drugs?
|
|
|
b1
alpha |
Which adrenergic (agonists)drugs cause stimulation to increase heart workload (contraindication)?
|
|
|
alpha
b1 |
Which adrenergic (agonists)drugs cause stimulation to increase BP dramatically?
|
|
|
B2
B1 |
_____ stimulation increases metabolism more, ______ increases heart palpatations and makes symptoms worse.
|
|
|
thyroid
|
What organ is the "metabolic center"?
