Use of formoterol in the treatment of stuttering. A pilot study.

Aims: Stuttering is a serious health and social problem that can distinctively affect not only the mental development of an individual but also his life possibilities, including social fulfilment and his general life prospects. The etiology of stuttering is however unknown and that is why it is not possible to treat it causally. This pilot study takes into account the hypothesis of bronchial constriction as a negative factor in stuttering and investigates the effect of the long-acting bronchodilator formoterol fumarate on stuttering in 42 patients.
