A reduced influx of mediator cells may explain some of the effects of INCS on rhinitis symptoms, but it cannot explain all of the effects because INCS also reduce the early-phase sneezing and rhinorrhea after an allergen challenge outside the pollen season.

These concerns persist for INSs despite significant or marked clinical differences between them and systemic corticosteroids in systemic absorption and among the INSs in bioavailability, mechanism of action, and lipophilicity, which may contribute to differences in AEs.

INCS may combine with the corticosteroid receptors in epithelial cells, which are then expelled into the airway lumen together with the dead epithelial cells or migrating inflammatory cells. Mechanistically, the glucocorticoid (GC) binds to the glucocorticoid receptor (GR) complex (with several heat shock proteins, and other proteins), located within the cytoplasm of the target cell (Adcock and Caramori 2001). It is not known whether INCS penetrate the nasal mucosa or act on target cells; however, their low systemic activity supports the concept of local action on nasal mucosa. It is not known whether INCS penetrate the nasal mucosa or act on target cells; however, their low systemic activity supports the concept of local action on nasal mucosa. Corticosteroid-induced inhibition of immunoglobulin E–dependent release of histamine is a possible but unproven mode of action. For example, the systemic bioavailability of the INSs as a percentage of the administered drug is less than … Objective: Clinical data and recent guidelines support the positive effects of intranasal corticosteroids on allergic rhinitis-associated ocular symptoms. 2017 Apr;72(4):636-644. doi: 10.1111/all.13056. doi: 10.1002/14651858.CD008268.pub3.Kumpitsch C, Koskinen K, Schöpf V, Moissl-Eichinger C.BMC Biol.
While INCS tended to improve asthma symptoms and forced expiratory volume in one second, the results did not reach significance.

Epithelial cells are an important target for corticosteroids, and INCS concentration is high at the epithelial surface.
