Ch.9 Mucus Controlling Drug Flashcards
What is mucoactive agent and what are the indications
General term used for any medication or drug that has an effect on mucus secretion
Indicated for diseases with hyper secretion or poor clearance in airways
What’s the difference between mucus, phlegm and sputum
Mucus: secretion from surface goblet cells and submucosal glands composed of water, proteins and glycosylated mucins
Phlegm: purulent material in airways
Sputum: phlegm that contains mouth, nose and resp tract secretions, contains bacteria and products of inflammation
What are the 5 functions of mucus in body
- Protection
- Lubricants
- Waterproof
- Protect against osmotic or inflammatory changes
- Traps microorganisms, inhibits chronic bacterial infections
What is mucoactive therapy used for
1.Reduce accumulation of airway secretions
2. Improve pulmonary function and gas exchange
3. Prevent repeated infection and airway damage

What is the rate of Mucociliary transport in the normal peripheral airway
1.5 mm/min
What is the healthy mucus secretion
Produces 100 ml of mucus every 24 hrs

What is the mode of action for NAC: N- Acetylcysteine
NAC substitute sulfhydryl radicals for disulfide bonds in mucus
Bronchospasms is most serious potential hazard associated with what
The use of acetylcysteine
When administering a medication such as NAC, what should be administered prior to acetylcyseine

- Laryngitis
- Rash
- Chest pain
- Conjunctivitis
What is the name of the agent that increase volume or hydration of airway secretions
Expectorants
What should patients with long term problems of secretion management do
They should be taught different airway clearance techniques
