7 important questions on RESPIRATORY - Nasal decongestants - Allergic Cough

What are sedative antihistamines used for in the context of allergic coughs?

Sedative antihistamines are used as cough suppressants. Examples include Promethazine, Chlorpheniramine, and Diphenhydramine. They inhibit H1 receptors (H1-receptor antagonist).

What are antitussives and when are they used?

Antitussives are cough suppressants used mostly when the cause is not known. Examples include Codeine, Dextromethorphan, Methadone, and Morphine. They act by depressing the cough centre.

What is the role of antibacterial drugs in treating coughs?

Antibacterial drugs are used to treat cough due to bacterial infection. Examples include Amoxicillin, Cephalexin, Cefuroxime, and Azithromycin.

How do expectorants function and give examples?

Expectorants promote expulsion of bronchial secretions. Examples include Guaifenesin, Ammonium chloride, and Ipecacuanha. They help in clearing mucus from the respiratory tract.

What can trigger a cough?

Cough can be triggered by inflammation in the respiratory tract, neoplasia, drugs, and undiagnosed asthma. Drugs like Angiotensin-Converting Enzyme Inhibitors (ACEIs) can also trigger cough.

What is the role of mucolytics and provide examples?

Mucolytics facilitate expectoration by reducing sputum viscosity. Examples include Bromhexine, Ambroxol, Carbocisteine, Erdosteine, Mecysteine, and Acetylcysteine.

What are mucokinetics and how do they function?

Expectorants and mucolytics are mucokinetics. A mucokinetic drug aids in clearance of mucus from the airways, lungs, bronchi, and trachea.
