Question

Salbutamol / Sodium cromoglycate in the treatment of acute attack of Bronchial asthma

Q140.3 marksShort Answers★✓

Answer

Salbutamol is the appropriate choice — a short-acting beta-2 agonist producing rapid bronchodilation (within minutes) via cAMP-mediated bronchial smooth muscle relaxation, exactly what an acute attack requires. Sodium cromoglycate is a mast cell stabilizer with no direct bronchodilator action and a slow onset of effect — it is used only for prophylaxis of allergic asthma, not for terminating an attack already in progress.
