DIAGNOSIS

1. ANAMNESIS

3. LABORATORYTESTS

2. CLINICALFEATURES

4. ALLERGOLOGICAL TESTS

Page 11: Asthma bronchiale

• sympatomimetics

• anticholinergics

• corticosteroides

• methylxantines

• antileucotriens

• antihistamines

Groups of drugs:

Page 12: Asthma bronchiale
Page 13: Asthma bronchiale
Page 14: Asthma bronchiale

β-mimetics

- nonselective - adrenaline, isoproterenol, orciprenaline, ephedrine

- selective - metaproterenol, albuterol, salbutamol, terbutalin, fenoterol => more effective via inhalation then per os administration => increase of cAMP

Parasympatolytics

ipratropium

Antiasthmatics with rapid effect:

Page 15: Asthma bronchiale

theophylline - myotropic influence via inhibition of phosphodiesterase and via influence on the adenosine receptors A2

=> bronchodilatation

=> prevention from bronchoconstriction caused by histamine, cholinergic agonists (metacholine) or exertion.

Aminophylline = theophylline + ethylendiamine

Methylxantines:

Page 16: Asthma bronchiale

inhibition of degranulation of mastocytes after exposition to specific agents full effect after 4-6 weeks

Drugs used for prevention and maintained treatment:

cromoglycate sodium

nedocromil• similar to cromoglycate in mechanism of action

Page 17: Asthma bronchiale

β2-mimetics with long-term effect:

• via inhalation salmeterol and formoterol • via per os ( tabl, sirup) klenbuterol, prokaterol, salbutamol

Teophylline with prolonged releasing

Page 18: Asthma bronchiale

zafirlukast zileuton montelukast

Antileucotriens =

Leucotriene Receptor Antagonists (LTRAs):

Page 19: Asthma bronchiale

beklometasone budesonide flunisolide fluticasone triamcinolone

potent antiinflammatory effect

decrease of number of inflammatory potent

cells

inhibition of bronchoconstrictory mechanisms

direct relaxation of smooth muscle cells

Corticosteroids:

Page 20: Asthma bronchiale

astemizole (Hismanal) clemastineterphenadineketotifen (Zaditen)

reversible competitive antagonists of H-receptors

Antihistamines:

Page 21: Asthma bronchiale

verapamile (Isoptin) nifedipine others

inhibition of calcium influx => inhibition of contraction of smooth muscle cells

induction of bronchodilatation

used experimentaly

Inhibitors of calcium channels:
