1. What does the binding of histamine to H1 receptors cause?

increased mucous production, constriction of bronchioles, decreased lung capacity, increase capillary permeability and swelling (edema), irritation of nerve endings (pain and itching), increased contractile force of cardiac muscle

2. What is anaphylactic shock?

the over secretion of histamine leads to the excessive leakage of capillaries and the dramatic drop in blood pressure and shock

3. What are leukotrienes?

potent inflammatory agents that are produced in the body from fatty molecules

4. What is true of leukotrienes in asthma?

it is the main harmful agent of asthma

5. what is SRS-A?

slow reacting substance of anaphylaxis, a leukotriene variant that plays a major role in asthma

6. What is a mucokinetic agent?

a compound that promotes the removal of excessive or abnormal mucus, thins out mucus and lets cilia move easier

7. What is sputum?

an abnormal viscous secretion, that is an excretory product of the lower lungs filled with DNA, dead microbes and WBC, and epithileal celss

8. What is Guafenesin?

an expectorant, used to break up mucus and stimulate cough, enhances production of respiratory tract fluids

9. How is guafenesin taken?

taken orally in syrup or tablets

10. What are the most common adverse effects of guafinesin?

GI issues, N/V/, annorexia
