[The effect of kavinton on bronchial tonus in bronchial asthma patients].

Intravenous cavinton given in a dose of 10 mg for 3 days was studied for its effects on bronchial tone in 40 patients with bronchial asthma. Respiratory parameters were pneumotaxometrically determined and cerebral circulatory parameters were rheographically measured prior to and following the drug injection. The findings have demonstrated that cavinton significantly decreased bronchial tone improved cerebral circulation, particularly in patients with bronchial asthma and chronic cerebral circulatory disorders.
