[The use of guacetisal in chronic obstructive bronchopneumopathy. Controlled clinical study].

A single-blind, between-patients trial was run to compare the fluidifying, expectorant, antitussive, antipyretic and anti-inflammatory activity, and the local and systemic tolerance of guacetisal, an active principle obtained by the esterification of acetylsalicylic acid and guaiacol, and oxolamine phosphate, in which the suspension formulation for adults was administered to 30 presenile and senile patients of both sexes with chronic obstructive bronchopathy. A higher activity on the part of guacetisal was noted. The results obtained are illustrated and discussed.
