The following was listed in the Self-Management Ideas section of the Sumer
1995 issue of Lifeline (Celiac Sprue Association):

Inhaled sodium cromolyn can suppress the coughing sometimes brought on by
angiotensin converting enzyme (ACE) inhibitors.  Nine of 10 patients in a
study of ACE-producing cough reported a marked improvement after taking
cromolyn for two weeks.

I am incapable of understand this statement and would appreciate help.

What is sodium cromolyn?

What is angiotensin converting enzyme (ACE) inhibitors?  How do they
contribute to cough?

How is any of this related to gluten/wheat intolerance?

Appreciate the help,  A Giannitelli
