1. It has been demonstrated that Robitussin exerted a significant beneficial effect in reducing the severity of chronic productive cough in 100 patients studied. In 50 patients to whom a placebo was alternately administered with the medication, the latter was significantly superior to the placebo.

2. The most striking effect of Robitussin was in reducing the tenaciousness of the sputum and thus rendering it easier to raise.

3. It also exerted a pronounced effect in reducing frequency of cough.

4. No significant undesirable side-reaction attributable to the medication was observed.
