Effect of Prostaglandin E1 Analog Misoprostol in An Ovalbumin-Induced Allergic Rhinitis Model.

ABSTRACT

OBJECTIVE: The aim of the present study was to demonstrate the effects of misoprostol in ovalbumin-induced allergic rhinitis (AR). The second purpose was to compare the effect profile of the combination of an antihistamine with misoprostol during treatment of AR. MATERIALS AND METHODS: Twenty-five adult male rats were used and were randomly classified into five groups (n=5) healthy+saline, AR, AR and desloratadine (D)-treated group, AR and misoprostol (M)-treated group, and AR and combined-treated group. RESULTS: Desloratadine administration had significantly lower nasal symptoms than the AR group, but nasal symptoms in the AR+M group were better than those in the AR+D group. The best improvement in serum IgE levels was seen in the misoprostol alone and combination treatment groups. CONCLUSION: We suggest that prostaglandins should be considered in the treatment of AR, and that the effects of these types of drugs should be tested clinically in patients.
