Comparison of effect of desloratadine citrate disodium tablets and loratadine dispersible tablets in treatment of patients with allergic rhinitis

Objective To compare the efficacy and adverse reactions of desloratadine citrate disodium tablets and loratadine dispersible tablets in treatment of patients with allergic rhinitis, and their influence on leukotriene B4(LTB4), interleukin-4(IL-4), interleukin-10(IL-10) and interferon gamma(INF-γ). Methods From June 2015 to June 2016, a total of 110 patients with allergic rhinitis in the Second People's Hospital of Cangnan County were selected and randomly divided into control group and observation group according to the digital table, with 55 cases in each group.The control group was given loratadine dispersible tablets, while the observation group was given desloratadine citrate disodium tablets.Both two groups were treated for 14 days.The clinical efficacy, adverse reactions and changes of LTB4, IL-4, IL-10, INF-γ levels before and after treatment were compared between the two groups. Results The total effective rate of the observation group was 94.5%, which was significantly higher than 80.0% of the control group(χ2=6.310, P 0.05). After 2 weeks of treatment, the levels of LTB4, IL-4, IL-10 and INF-γ in the observation group were (67.74±10.15)ng/L, (52.37±5.12)μg/L, (81.26±11.78)μg/L, (94.47±7.87)μg/L, respectively, which in the control group were (80.32±9.97)ng/L, (62.95±5.45)μg/L, (96.32±11.57)μg/L, (86.74±7.63) μg/L, respectively, there were statistically significant differences between the two groups(t=7.124, 5.262, 4.654, 3.718, all P<0.05). Conclusion Both desloratadine citrate disodium tablets and loratadine dispersible tablets can effectively treat patients with allergic rhinitis, improve the symptoms and physical signs, reduce the levels of LTB4, IL-4 and IL-10, increase the level of INF-γ, and the adverse reactions are less and slight, but the efficacy of desloratadine citrate disodium tablets is better than loratadine dispersible tablets.
