Sodium cromoglycate: a remedy for ACE inhibitor-induced cough

The beneficial effects of angiotensin converting enzyme (ACE) inhibitors may be limited by cough, for which the only consistently effective treatment is withdrawal of therapy. The effect of inhaled sodium cromoglycate (20 mg, 4 times daily) was examined in five patients who experienced cough following the introduction of an ACE inhibitor. In three patients inhaled cromoglycate suppressed the cough. Inhaled sodium cromoglycate may thus be of value in a proportion of patients with ACE inhibitor-induced cough.
