[Value of ipratropium (Atrovent) in the treatment of chronic obstructive lung diseases in myasthenic patients treated with anticholinesterase agents. Apropos of a case].

We report a case of myasthenia gravis occurring in a 70-year old patient with old chronic bronchitis. Anticholinesterase therapy led to an increase in respiratory symptoms, but relief was obtained with inhaled ipratropium. The activity of this drug was confirmed by spirography. This clinical finding is compared with similar data found in the literature.
