Q

atropine

  • indications
  • cautions/warnings
A
  • indicated for temporary blockage of severe or life threatening muscarinic effects
  • when recurrent use of essential in patients with coronary artery dz, total dose should be restricted to 2-3mg to avoid detrimental effects of atropine-induced tachycardia of myocardial oxygen demand

16
Q

ipratropium

A

used as bronchodilator for maintenance treatment of bronchospasm
- poorly absorbed after aerosol administration -> relatively free of systemic atropine-like effects

17
Q

tiotropium

A

indicated for the long-term, once-daily maintenance treatment of bronchospasm

18
Q

aclidinium

A

indicated for long-term maintenance treatment of bronchospasm associated with COPD

19
Q

What are the methylxanthines listed? (3)

A

theophylline, theobromine, caffeine

20
Q

What are the two distinct actions of theophylline in the airways of patients with reversible obstruction?

A
  1. smooth muscle relaxation

2. suppression of the response of the airways to stimuli

21
Q

What are the extreme cautions listed for theophylline?

A

active peptic ulcer disease, seizure disorders, cardiac arrhythmias
- due to increased risk of exacerbation

22
Q

What are the most effective anti-inflammatory asthma controllers?

A

inhaled corticosteroids (ICS)

  • they reduce eosinophils and sputum (several effects on the inflammatory process)
  • they switch off the transcription of multiple activated genes that encode inflammatory proteins
23
Q

What does a withdrawal of ICS result in?

A

slow deterioration of asthma control, indicating that they suppress inflammation and symptoms, but do not cure the underlying condition

24
Q

What are the inhaled corticosteroids used to treat asthma? (7)

A

beclomethasone, budesonide, ciclesonide, flunisolide, fluticasone, mometasone, triamcinolone

25
beclomethasone - indications - cautions
- prescribed as maintenance treatment for asthma and as prophylactic therapy in pt >5 years - death due to adrenal insufficiency has occured in asthmatic patients during and after transfer from systemic corticosteroids to less systemically available inhaled corticosteroids NOTE: after withdrawal from systemic corticosteroids, a number of months are required for recovery of HPA function
26
budesonide - indications - cautions
- maintenance treatment of asthma as prophylactic therapy - should NOT be used with primary treatment of status asthmaticus or other acute episodes of asthma - also contraindicated in people with hypersensitivity to milk proteins
27
ciclesonide - indications - cautions
- maintenance treatment of asthma as prophylactic therapy in adults >12 years old - NOT indicated in releif of acute bronchospasm**. use also not recommended in presence of candida albicans** infection
28
flunisolide - indications - cautions
- maintenance and treatment of asthma as prophylactic therapy in patients >6 years - contraindicated in patients for primary treatment of status asthmaticus NOTE: flunisolide may reduce or eliminate the need for oral corticosteroids
29
mometasone - indications - cautions
- maintenance treatment of asthma as prophylactic therapy | - contraindicated in patients with a known hypersensitivity to milk proteins
30
triamcinolone - indications - cautions
- maintenance treatment of asthma as prophylactic therapy, also patients who require systemic corticosteroid administration NOTE: not indicated for the relief of acute bronchospasm - contraindicated in primary treatment of status asthmaticus or other acute episodes where intensive measure are required. deaths due to adrenal insufficiency have occured
31
prednisone - indications - cautions
- anti-inflammatory or immunosuppressive agent, used for treatment of certain endocrine conditions - may lead to HPA axis suppression
32
What are the leukotriene antagonists listed?
montelukast, zafirlukast
33
What are leukotriene antagonists used for?
treatment and prevention of acute asthmatic attacks - they bind to CysLT receptors and block their activation and the subsequent inflammatory cascade commonly associated with asthma and allergic rhinitis
34
montelukast | leukotriene antagonists
- treats allergies and prevents asthma attacks, by inhibiting actions of LTD4 at the CysT1 receptor without any agonist activity - NOT indicated for use in the reversal of bronchospasm in acute asthma attacks
35
zafirlukast - indications - cautions
selective and competitive receptor antagonist of LTD4 and LTE4, components of slow reacting substance of anaphylaxis (SRSA) - prophylaxis and chronic treatment of asthma - hepatotoxicity -> cases of life-threatening hepatic failure have been reported
36
Zileuton
5-lipoxygenase inhibitor, inhibits LTB4, LTC4, LTD4, LTE4\- used as prophylaxis and chronic treatment of asthma - NOT recommended in cases where active liver disease or persistent hepatic fuction enzymes are >3 times upper limit of normal NOTE: immediate-release tablets were withdrawn from US market in 2008
37
omalizumab | - indications
anti-IgE antibody - moderate to severe persistent asthma in patients >6 years, also for treatment of chronic idiopathic urticaria in adults >12, who remain symptomatic despite H1 antihistamine treatment - anyphylaxis!! administer only in healthcare setting because reaction can be life-threatening. observe patients for an appropriate period of time after administration
