In all patients in the nasal and oral groups, one tablet was given before bed. The following results were obtained:<br>1) The rate of desease of common cold did not significantly differ among the three groups. (x<sup>2</sup> test)<br>2) In the nasal and oral groups, the rate of preventing progression was higher than in the control group (P<0.05). (nasal group 90±22%, oral group 91±20%, control group 76±38%)<br>3) The affected period was significantly shorter in the nasal group than in the control group. (P<0.05), but there was no significant difference between the nasal and oral groups or between the oral and control groups (The period of affection: nasal group 4.29±3.53 days, oral group 6.45±5.84 days, control group 8.06±6.11 days)<br>4) When the initial symptom was epipharyngalgia, the administration of Azunol® ST in the nasal cavity completely prevented (100%) the progression of symptoms, however, the rate of preventing progression was not significantly different between the oral (61%) and control groups (70%).
