12 Questions
How do mucolytic agents alter mucus in the respiratory tract?
By cleaving disulfide linkages within high molecular weight mucin glycoproteins
What is the primary role of mucolytics in the respiratory tract?
Enhance airway clearance
Which mucolytic agent improves mucociliary clearance by reducing sputum viscoelasticity?
Erdosteine
How do classical mucolytic agents like N-acetylcysteine work?
By reducing disulfide linkages in mucus glycoproteins
What is the effect of N-acetylcysteine on exacerbations and hospitalizations in chronic bronchitis patients?
It reduces exacerbations and hospitalizations
Which mucolytic agent has antioxidant and anti-inflammatory properties?
Erdosteine
What is the role of DNase in mucous plugs?
Hydrolyzing DNA, increasing sputum volume, and improving cough frequency and viscosity
Why has the use of DNase been associated with increased respiratory infections?
As a side effect of its impact on mucus rheology
Which mucolytic agent is known for reducing cough frequency, severity, sputum volume, and stickiness?
Carbocisteine
What effect has Acetylcysteine been shown to have in COPD patients?
Reducing COPD exacerbations, improving lung function, and increasing survival
What is the impact of Solmuclitabine on COPD patients compared to placebo?
Increasing time to exacerbation and FEV1 levels
Why is further research needed on mucolytics according to the text?
To understand the potential side effects of mucolytics
Explore the world of mucolytic agents, drugs that alter mucus in the respiratory tract to enhance airway clearance and treat productive cough. Learn about how these agents help in acute and chronic respiratory conditions by reducing mucus viscoelasticity. Dive into the synthetic N-acetyl-L-cysteine derived mucolytics available in the western world.
