Drugs Affecting the Respiratory System Flashcards
responsible for PROCESSING the O2 into the blood system and EXHALING CO2
respiratory system
2 major parts of the respiratory system
upper and lower respiratory system
consists of the pharynx, tonsil, epiglottis, larynx, and trachea
upper respiratory system
consists of the lungs, bronchial tubes, pleura, diaphragm, alveolus
lower respiratory system
common respiratory disorders
- asthma
- chronic obstructive pulmonary disorder (COPD)
- cystic fibrosis
- tuberculosis
asthma pertains to the __________________ narrowing and inflammation of the airway caused by _______________
episodic narrowing and inflammation caused by stimuli
chronic bronchitis and emphysema
COPD
thick secretion excreted into the lung
cystic fibrosis
tuberculosis is an infection caused by ___________________________________
Mycobacterium tuberculosis
T/F: COPD is irreversible and progressive while ASTHMA is reversible and episodic
TRUE
use of controller drugs
prevent asthma episodes
(CE –> control episode)
use of reliever drugs
specifically for asthma attack
(RA –> relieve attack)
emphysema affects which part of the respiratory system?
alveoli
T/F: We can give NSAIDs to asthmatic patients along with inhaled corticosteroids (ICS)
FALSE (do not give NSAIDs)
Drugs used in asthma
- bronchodilators
- anti-inflammatory agents
- leukotriene antagonist
drugs under bronchodilators
- beta 2 agonist
- methylxanthines
- muscarinic antagonist
drugs under anti-inflammatory agents
- release inhibitors
- antibodies
- steroids
drugs under leukotriene antagonist
- LOX inhibitor
- receptor inhibitor
condition caused by inflammation of the airways or constrictions
asthma
asthma treatment involves?
- dilation of airway
- reduction of inflammation
T/F: Sympathomimetic agents cause bronchoconstriction
FALSE: bronchodilation
sympathomimetic agents are what type of agonist
adrenoreceptor agonist
sympathomimetic agents stimulate adenylyl cyclase (AC) causing ________________________
increase in the formation of intracellular cAMP
sympathomimetic agents binds to _____________________ stimulating cAMP in the smooth muscle –> relaxation and inhibit release of bronchoconstriction mediators from mast cells
beta-receptor
enumerate the sympathomimetic agents
- epinephrine
- ephedrine
- isoproterenol
- beta-selective drugs (SABA, LABA, U-LABA)
enumerate the SABA drugs
AlTeMePir: Albuterol, Terbutaline, Metaproterenol, Pirbuterol
enumerate the LABA drugs
ForSal: Formeterol (full agonist) and Salmeterol (partial agonist)
enumerate the U-LABA drugs
InOlVi: Indacaterol, Olodaterol, Vilanterol
sympathomimetic agents are best delivered through what route?
inhalation
Rapid-acting bronchodilator when injected SC or as inhaled as micro aerosol
epinephrine
epinephrine is a rapid-acting bronchodilator when injected _________________ or as
____________________
subcutaneously or inhaled as micro aerosol
epinephrine max bronchodilation is achieved ______________________ inhalation and last for _______________________
15 minutes after ; last for 60-90 minutes
stimulates alpha, B1, & B2 receptors
epinephrine
as epinephrine stimulates alpha, B1, & B2 receptors, it may cause?
TAW: tachycardia, arrhythmia, worsening of angina pectoris
epinephrine may also be used for treating ___________________, ______________, and ________________________
acute vasodilation, shock, and bronchospasm of anaphylactic shock
compared to epinephrine, ephedrine has a ____________________ DOA
longer
has a more pronounced central activity and a much lower potency
ephedrine
infrequently used in the management of asthma
ephedrine
a sympathomimetic agent that is a potential nonselective B1 & B2 bronchodilator
isoproterenol
rarely used for asthma
isoproterenol
isoproterenol _______________________ causes bronchodilation within ___________________
80-120 mcg; 5 minutes
DOA of isoproterenol
60-90 minutes
