[Meta-analysis of pharmacotherapies for allergic rhinitis].
We performed meta-analysis using the data in literatures of the clinical study related to pharmacotherapies for allergic rhinitis in Japan as evidences. We extracted double-blind studies which used first-generation antihistamines, early-stage second-generation antihistamines, late-stage second-generation antihistamines and arachidonic acid metabolite-receptor antagonists as investigational drugs. In meta-analysis of first-generation antihistamines and early-stage second-generation antihistamines, significant differences between them were detected in final overall improvement and usefulness. In meta-analysis of early-stage second-generation antihistamines and late-stage second-generation antihistamines, significant differences between them were detected in usefulness and sleepiness as an adverse effect. In meta-analysis of late-stage second-generation antihistamines and arachidonic acid metabolite-receptor antagonists, significant differences between them were detected in final overall improvement and usefulness. These results indicate a historical trend in the development of drugs including measures to deal with sleepiness as an adverse effect. The arachidonic acid metabolite antagonists appeared to be promising among the oral drugs for allergic rhinitis, although data related to the arachidonic acid metabolite antagonists are still few and further collection of them is necessary.
