Abstract
In order to evaluate the efficacy of AZ-S tablets (GASN 5mg) on pharyngitis, a double blind test was performed with AZ-U gargle tablets (GASN 2mg) as a control. The subjects were 45 patients with pharyngitis for AZ-S and 48 for AZ-U. All the AZ-S tablets were administered into the labiogingival region of the upper jaw.
1. AZ-S tended to be more effective for spontaneous pain and reddness of the pharyngeal mucous membrane than AZ-U (p<0.10). AZ-S was significantly more effective for swelling and discomfort in the pharynx (p<0.05).
2. Pharyngitis was cured in significantly shorter periods with AZ-S than with AZ-U (p<0.05).
3. Overall efficacy tended to be superior with AZ-S tablet (p<0.10).
4. No obvious side effect attributable to AZ-S or AZ-U was observed.
5. From the above results, AZ-S tablets administered into the labiogingival region of the upper jaw was considered to be more effective for pharyngitis than AZ-U gargle tablets.
