Term
two classes of asthma treatment
Definition
bronchodilators- relieve acute symptoms , anti inflammatory agets - used to control/prvent symtpoms
Term
bronchodilators moa and types
Definition
increased cAMP0 either via b-agonists, or pde inhibitors (which normally break down camp). muscarinic ad adenosine antagonists blocks broncdhoconstrictoin.
Term
b-agonists actions in asthma
Definition
relax bronchial smc, inhbiit the realeas eof bornhoonstrictors from mast cells. inhibit microvascular leake andi icnreasemucocilliary trasport
Term
nonselective b agonists actions
Definition
stimulates b2 receptors- bronchodilation, and b1 receptors- cardio side effects. epinephrine. NOT FOR CHRONIC USE,
Term
ephedrine
Definition
nonsleective b agonists, muchlower potency than epinephrile but orally active
Term
isoprotenerol
Definition
nonselective b a gonist, very poten t but shrot acting bronchodilator. mosly use dto emergencies
Term
b2 selective adrenorecpetor agoists
Definition
both short actinga and long acting. Last logner than nonselective agaonsits. used for relie of acute asthma smtpoms adn bronchospasm
Term
albuterol
Definition
shortactingselective b2 agonist, all b2 agonists end in-ols,
Term
b2 agonist delivery
Definition
inhaler, oral, subcu.
Term
when to use oral therapy
Definition
used frequqently i chidlren, ho can controll meter dose, or patient with very severe asthma that aerosol iritates them. adverse effects include: skeletal muscle tremr, nervousnes,s ocassional weakness
Term
subcu therapy for b 2 agonist used when?
Definition
emergency treatment where aerosol not usable. teru ullatiilien is the only one
Term
salmeterol
Definition
long acting b2 agonist
Term
salmeterol
Definition
long acting b2 agonist
Term
formoterol
Definition
llong acting b2 agonist
Term
long acting b2 agonist duration of action
Definition
12 hours or more, slow onset, so cant be used for acute exacerbation,
Term
use of long acting b selective
Definition
with inhaled corticosteroids, not used alone because no antiinflammatory effect
Term
Bitolterol
Definition
a potent selective b2 receptor agonist that is long acting AND works acutely. available as nebulizer
Term
theophyllinne
Definition
methylxanthinedurgs
Term
methylxanthine drugs moa
Definition
inhibit PDE- increasing camp, also inhibit adenosine- which inhibits bronchoconstriction
Term
methylxanthien drug utility
Definition
relaxatio of airway smc major hteapurtic action in asthma. Cn alo improv contrcitly of isolated skeletal muscle, reverse fatigue of daiaphragm in patietn with copd. use fo racute asthma
Term
adverse effect sof methylxanthi e drugs
Definition
cns effects, cardio effects, gi effects,
Term
methylxanthine method of admin
Definition
orally and parenterally
Term
treatment with theophylline gudeliens
Definition
constnat monitoing of plasma levels. needs to be bewee 5-20 mg/L
Term
muscarainic antaognists
Definition
antiparasympathetic , avoid cbronchoconstriction
Term
atropine asthma use
Definition
muscarinic antagonist, however adverse effects may occur including cardiac effects
Term
ipratropium romide type
Definition
mucarinic recpeotr antagonist ,
Term
ipratropium bromide properites
Definition
qurternary ammonium , so delivered inhaled, without entering cns or beinga bsorbed ssytemtically. used in combo with b2 agonist . effective in COPD
Term
ipratropium bromide properites
Definition
qurternary ammonium , so delivered inhaled, without entering cns or beinga bsorbed ssytemtically. used in combo with b2 agonist . effective in COPD
Term
tiotropium bromide
Definition
logner acting version ofipratropium
Term
corticosteroids use
Definition
DO NOT relax smc. inhibit mucousal inflammation in asthamtic airways, antiinflammtoryenffect by reducing cyotkiens/chemokines. eicosanoid synth, inhib acumulation of phils ad luekotrienes.

reduce frequency of asthma excaerbations, potentiates teh eects of b agonists when administered chronically
Term
adminitratiomethod corticosteroids asthma
Definition
almost always given aerosol to reduce adverse effects , unless emergencythen given orally
Term
-ones, and -ides
Definition
coritocsteroids
Term
corticosteroid adverse effectsasthma
Definition
oropharyngeal candidiasis, grwoth retardation possile in children
Term
cromoln sodium , nedocormil sodium moa
Definition
used prophylactically only. delayed cholride channel activvation , inhibitign celluar activation.
Term
chromne drugs
Definition
pretreatment, blocks bronchoconcstriction, must be taken at least an hour bbefore exposed, may prevent trigger from working. may reduce need for bronchodilation. can be usedf or rhinonjunctivis.
Term
zileutin moa
Definition
antiluekotriene. bock 5lipoxeygenase, prventing luekotriene syntehsis
Term
zafirulukast
Definition
ltd4 receptor antatogonist
Term
montelukast
Definition
ltd4 receptor antatogonist
Term
antiluekotriene effects
Definition
block airway reponse, reduce bronchial reactivity and iarway inflammation so have less exacerbations. However not everyone respodns to it
Term
antiluekotriene administration
Definition
can be given orally , if inhalation is not an option
Term
anti
