Ambroxol is a mucolytic.

• A. Ambroxol
• B. Carbocisteine
• C. Ibuprofen
• D. Amlodipine

Answer: (A)

Mucolytics work by thinning and loosening mucus to make it easier to clear from the airways. Ambroxol is a mucolytic because it helps reduce mucus viscosity and promotes the production of a more serous, watery mucus that is easier for the cilia to transport. It also can boost the production of surfactant in the lungs, which helps keep the airways open and supports efficient clearance of mucus. Clinically, this makes ambroxol useful for productive coughs with thick, sticky secretions.

The other options aren’t mucolytics: ibuprofen is an anti-inflammatory drug, and amlodipine is a calcium channel blocker used for hypertension and other cardiovascular conditions. Carbocisteine is another mucolytic, but the choice highlighted in this question is ambroxol.
