Effects of Varidase buccal tablets on the sputum.

Samples of sputum were collected from ten patients with chronic respiratory diseases following treatment with Varidase (streptodornase and streptokinase) buccal tablets, four tablets per day for a period of seven days, and were compared with specimens obtained before the therapy in terms of rheological and cytochemical parameters. The study revealed a tendency for the respiratory secretion to show a lowered yield point and a decrease in mucous fibers after the therapy, thus suggesting, to some extent, the efficacy of the drug as an expectorant.
