Abstract
Current medications to treat allergic rhinitis (AR) include antihistamines, corticosteroids, and anti-leukotrienes. In the present study, we investigated the effects of combination therapy; using these drugs, and evaluates the AR-related markers and parameters in an animal model.
After inducing BALB/c mice AR models, the animals were treated with either pranlukast, loratadine, fluticasone, loratadine + fluticasone, loratadine + pranlukast, fluticasone + pranlukast, or loratadine + fluticasone + pranlukast. Clinical symptoms, Immunoglobulin (Ig)G1, ovalbumin (OVA)-specific and total IgE, leukotriene (LT)B4, LTC4, histamine, thymic stromal lymphopoietin (TSLP) serum levels, and interleukin 4 levels in the nasal lavage fluid were determined. The expressions of HRH1, CysLT1R, NLR3, Caspase-1, and MUC5a were studied.
Allergic symptoms (nasal rubbing and sneezing), serum Igs (IgG1, total and OVA-specific IgE), eicosanoids (LTB4 and LTC4), histamine, TSLP, and IL-4 as well as gene expressions of MUC5a, Caspase-1, NLR3, HRH1, and CysLT1R were reduced in the animals receiving each of the therapeutic regimens; however, more pronounced effects were seen in the group treated with the triple combined protocol (loratadine + fluticasone + pranlukast).
The combination of the loratadine, fluticasone, and pranlukast can effectively control the symptoms of AR probably via modulating several related mechanisms at the early and late phases of allergic responses.
