[Controlled clinical study of doxophylline versus aminophylline in the treatment of acute cardiorespiratory insufficiency syndromes].

Twenty patients of both sexes, hospitalized because they were suffering from acute cardiorespiratory syndromes, have been studied in a clinical blind test on unbalanced groups of patients. This research aims to evaluate the therapeutic efficiency and intravenous tolerance of doxophylline. Patients were observed for 24 hours. Signs and symptoms were recorded on a semi-quantitative scale, and the clinical situation, haemogasanalysis, blood pressure, cardiac frequency, and other analytic controls were performed in order to verify the systemic tolerability. We can conclude, in agreement with the literature, that the group treated with doxophylline showed a better reduction in cardiac frequency, while maintaining the same effects on the respiratory apparatus.
