Match List I with List II
Show Hint
Bromhexine is a highly classic "mucolytic" agent (C-II) that thins mucus.
Water aerosols directly hydrate/dilute secretions (D-I).

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Expectorants are respiratory drugs that facilitate the removal of bronchopulmonary secretions from the respiratory tract by decreasing viscosity or increasing fluid volume.
Step 2: Detailed Explanation:
Let us analyze each class of expectorant:
- A. Secretory expectorant: Ipecacuanha acts by irritating the gastric mucosa, triggering a sensory vagal reflex that stimulates bronchial glands to secrete watery mucus.
Thus, A matches with IV.
- B. Saline expectorant: Inorganic salts like Potassium iodide are absorbed and excreted by bronchial glands, osmotically drawing water into the respiratory secretions.
Thus, B matches with III.
- C. Mucolytic expectorant: Bromhexine acts directly by depolymerizing mucopolysaccharide fibers in mucus, lowering its viscosity.
Thus, C matches with II.
- D. Diluent expectorant: Inhaled water aerosols or saline aerosols act directly as diluents to hydrate and thin thick secretions.
Thus, D matches with I.
Step 3: Final Answer:
The matching sequence is A-IV, B-III, C-II, D-I, which is represented by option (A).
