asthma Flashcards
What are the two LTRA’s available for use in treating asthma?
- zafirlukast (Accolate)
- montelukast (Singulair)
Abreviation for leukotriene receptor agonist
What does LTRA stand for?
Montelukast may also inhibit symptoms of allergic rhinitis becuase…
leukotrienes are also released from the nasal mucosa during allergen exposure.
Methylxanthines have declined in the importance in the treatment of asthma, but some patients may still benefit from the use of…..
theophylline
Leukotriene receptor agents work by…..
decreasing the inflammation in the lungs with people with asthma
What is the most commonly prescribed beta2 receptor agonist?
-albuterol (Ventolin, Proventil)
What is the trade name for levalbuterol?
What is the generic name for Xopenex?
What is the trade name for salmeterol?
What is the generic name for Serevent?
The perfect bronchodilator would work only on the beta2 recceptors in the lungs and have no other effects, however other systems affected include?
CV, skeletal muscles, and the CNS
What is the approximate duration of a long acting beta agonist?
About 12 hours
long acting beta agonists must be used in conjunction with?
A steroid because of the risk of adverse reactions, particularly in children.
What are the long acting beta agonist drugs?
- salmeterol
- formoterol
- bambuterol
Short acting beta agonists typically have an onset of 3-5 minutes and a duration of?
4-6 hours
What is the route, dose, and frequency for levalbuterol (xopenex)?
liquid form in a nebulizer, 0.63-1.25 mg, q6-8 hours
What is the trade name for salmeterol?
What is the generic name for Serevent?
beta agonists can affect the muscles by…..
causing shakiness, and cramping of the hands legs and feet.
For adults 12 years and older, what is the preferred treatment for intermittent asthma?
This is step 1 and it is a SABA PRN
For adults 12 and older, what is the preferred treatment for mild persistent asthma?
This is step 2 and is a low dose ICS and a SABA PRN
For adults 12 and older, what is the preferred treatment for step 3 moderate persistent asthma?
Either a medium-dose ICS or a low-dose ICS in conjunction with a LABA
For adults 12 and older, what is the preferred treatment for step 4 moderate persistent asthma?
A medium dose ICS with a LABA
When considering preferred versus alternative treatment plans in asthma, use of a LABA is not considered until?
beginning in step 3
In adults 12 and older, what is the preferred method of treatment for step 5 severe persistent asthma?
A high dose ICS with a LABA
In adults 12 and older, what is the preferred method of treatment for step 6 severe persistent asthma?
A high dose ICS, LABA, and an oral corticosteroid
What is a leukotriene agonist?
A leukotriene antagonist (sometimes referred to as a leukast) is a drug that inhibits leukotrienes, which are fatty compounds produced by the immune system that cause inflammation in asthma and bronchitis, and constrict airways.
