[Clinico-functional observations on the use of guacetisal in the treatment of chronic obstructive bronchopneumopathy].

The results of an approximately 14-day treatment with 500 mg broncaspin capsules in 25 patients with recrudescent chronic bronchitis are presented. There was a marked, constant improvement in the subjective and objective symptomatology, and in respiratory function indices. The expectoration cell parameters displayed changes consonant with the therapeutic effect. Local and general tolerance were good overall.
