Anticholinergic drugs for asthma
Fast-acting treatment for asthma
-Tiopropium and Iprapropium
-block acetylcholine binding (remember this is NT transmitter released in the
parasympathetic stimulation which causes constriction of the bronchi by blocking it, we
decrease the parasympathetic response therefore preventing constriction.
-Atrovent & Spiriva both prevent the muscle
bands around the airways from tightening
thus reduce in exacerbation.
Asthma
A chronic allergic disorder characterized by episodes of severe breathing difficulty,
coughing, and wheezing.
-Characterized by: 1. Airway inflammation 2. Bronchial hyperactivity 3. Intermittent,
reversible airflow obstruction.
causes of asthma
complex interaction of genetic and environmental factors
Results in:
1. Excess mucus production/accumulation
2. Hypertrophy of smooth muscle
, 3. Airflow obstruction
4. Decreased alveolar ventilation.
extrinsic asthma
triggered by a chronic allergic reaction
eg - mold, pollen, dust mites, pet dander
-elevated IgE level is diagnostic
-more common, especially in
children (males:females = 2:1)
S/S
Coughing, wheezing, SOB, tachypnea, chest tightness.
Intrinsic asthma
-triggered by a variety of non-allergic
factors
eg - chemicals, air-borne irritants,
infections (esp. viral),
exercise, stress, anxiety, GERD,
obesity
-no initial elevation in IgE level
-typically seen in adults (<40 y/o) (slightly more common in females)
patho of asthma
1.Allergen enters body
