Fifty-six patients with seasonal allergic rhinitis were hyposensitized with aqueous extracts (23 patients) and Allpyral extracts (33 patients). The clinical course was appraised objectively on the basis of rhinomanometry findings at examinations performed before hyposensitization and one year later. There was no essential difference between the two groups of patients as regards the relief of symptoms. A reduction of nasal congestion was recorded in 54 and 58% of the patients, respectively. Complications were less severe and less frequent in the Allpyral group.
