Q

Beta2 Adrenergic Agonists- Classification

A

bronchodilator

2
Q

Beta2 Adrenergic Agonists- Mech of Action

A
  • stimulate adenylyl cyclase causing increase of cAMP resulting in bronchodilatation
  • inhibits relase of mediators from mast cells that cause bronchospasm
3
Q

Beta2 Adrenergic Agonists- Route of Administration

A
  • inhalation
  • oral
  • subcutaneous (terbutaline only)
4
Q

Beta2 Adrenergic Agonists- Therapeutic Use

A
  • symptomatic relief of bronchospasm in acute asthma attacks
5
Q

Beta2 Adrenergic Agonists- Unique Use

A
  • subcutaneous terbutaline for atatus asthmaticus

- bitolterol for nocturnal asthma

6
Q

Beta2 Adrenergic Agonists- Side Effects

A
  • skeletal muscle tremor
  • anxiety
  • tachycardia
7
Q

Theophylline- Classification

A

bronchodilator

8
Q

Theophylline- Mech of Action

A
  • inhibits cAMP phophodiesterases causing increase of cAMP resulting in bronchodilation
  • competititive antagonist at adenosine receptors resulting in bronchodilation
9
Q

Theophylline- Routes of Administration

A
  • oral

- slow IV over 40 min.

10
Q

Theophylline- Therapeutic Use

A

maintenance therapy for chronic asthma

11
Q

Theophylline- Unique Use

A

sustained-release oral theapy for nocternal asthma

12
Q

Theophylline- Major Side Effects

A

NARROW THERAPEUTIC INDEX

  • fasciculations
  • generalized convulsions
  • tachycardia
  • circulatory collapse
13
Q

Ipratropium Bromide- Classification

A

bronchodilator

14
Q

Ipratropium Bromide- Mech of Action

A
  • antagonist at muscarinic receptors leading to decreased inositol triphosphate, causing decreased release of Ca ions from endoplasmic reticulum resulting in bronchodilatation
15
Q

Ipratropium Bromide- Routes of Administration

A

inhalation

16
Q

Ipratropium Bromide- Therapeutic Use

A

alone or in combination with beta2-adrenergic agonist in acute asthma attacks

17
Q

Ipratropium Bromide- Unique Use

A

when a coexisting chronic bronchitis or cough is the predominant symptom in asthmatic patients

18
Q

Ipratropium Bromide- Side Effects

A

local drying of mouth

19
Q

Adrenal Corticosteroids- Classification

A

Anti-inflammatory agent

20
Q

Adrenal Corticosteroids- Mech of Action

A
  • increases synthesis of lipomodulin, which inhibits phospholipase A2 which suppresses release of arachidonic acid, which inhibits release of leukotrienes and prostaglandins, resulting in bronchodilatation
21
Q

Adrenal Corticosteroids- Routes of Administration

A
  • inhalation
  • oral
  • IV
22
Q

Adrenal Corticosteroids- Therapeutic Use

A

maintenance therapy for chronic asthma

23
Q

Adrenal Corticosteroids- Unique Use

A

treats the underlying inflammation of asthma, reducing frequency and severity of attacks

24
Q

Adrenal Corticosteroids- Side Effects

A
  • systemic from oral therapy

- local such as oropharyngeal candidiasis, dysphonia, dry mouth and cough from inhalation therapy

25
Q

Cromolyn Sodium- Classification

A

anti-inflammatory agent

26
Q

Cromolyn Sodium- Mech of Action

A

decreases Ca influx by IgE Ab and thereby inhibits release of mediators from mast cells that cause bronchospasm

27
Q

Cromolyn Sodium- Routes of Administration

A

inhalation

28
Q

Cromolyn Sodium- Therapeutic Use

A

prophylactic therapy for preventing bronchospasm

29
Q

Cromolyn Sodium- Unique Use

A
  • prior to exercise challenge

- prior to cold air challenge

30
Q

Cromolyn Sodium- Side Effects

A

occasional coughing

31
Q

Zafirlukast- Classification

A

leukotriene inhibitor

32
Q

Zafirlukast- Mech of Action

A

complete with LTD4 at its receptor site on airway cells to block bronchoconstriction and inflammation

33
Q
