ABSTRACT
Background: Intranasal corticosteroids (INCS) are the cornerstone of treatment for chronic rhinosinusitis. Although INCS are generally considered safe and effective, there is a concern that chronic use may lead to ocular adverse effects. Objective: To assess ocular safety of the exhalation delivery system with fluticasone propionate (EDS-FLU) in patients with chronic rhinosinusitis with nasal polyps. Methods: Ocular safety data were collected during two randomized, double-blind, placebo controlled studies with open-label extensions. Ophthalmologists performed tonometry, slit-lamp, and visual acuity examinations to assess intraocular pressure (IOP) and the presence of cataracts. Ocular examinations were conducted before double-blind treatment, at the end of the 16-week double-blind phase, and at the end of the 8-week open-label phase. The results of pooled data from patients who received EDS-FLU 186 µg (n = 160), EDS-FLU 372 µg (n = 161), and EDS-placebo (n = 161) twice daily are reported here. Results: At the end of the double-blind phase, six patients developed elevated average IOP > 21 mm Hg: two patients (1.2%) in the EDS-placebo group, three patients (1.9%) in the EDS-FLU 186 µg group, and one patient (0.6%) in the EDS-FLU 372 µg group. In addition, 6 of 482 patients developed cataracts: 3 patients in the EDS-placebo group, 2 patients in the EDS-FLU 186 µg group, and 1 patient in the EDS-FLU 372 µg group. At the end of the open-label phase, two additional patients showed IOP > 21 mm Hg and two additional patients developed cataracts. Conclusion: No increased risk of elevated IOP was detected with EDS-FLU; the rate of cataract development was similar to EDS-placebo and to that reported with other INCS.Clinical trials NCT01622569 and NCT01624662,

Inhaled corticosteroids (ICS) are the guideline-preferred preventative therapy for persistent asthma of all severity levels and for all ages, including children. While these drugs are unquestionably efficacious, concerns of adverse systemic effects limit patient compliance with treatment regimens and thus the attainable benefits. Suppression of bone growth, bone density, and HPA axis function, in addition to cataract formation and elevated intraocular pressure/glaucoma, have been associated with ICS use. This review will focus on recent developments in the safety and efficacy of ICS as compared to oral CS corticosteroids and the achievement of a balance between risk and benefit in optimizing ICS therapy.

Inhaled corticosteroids (ICSs) are the preferred first-line preventative therapy for asthma of all severity levels. Although these drugs have been proven efficacious, concerns of adverse systemic affects due to both long- and short-term use continue to limit patient compliance with dosing regimens. Deficits in bone growth, bone density, and hypothalamic-pituitary-adrenal axis function, in addition to cataract formation and elevated intraocular pressure/glaucoma, have been associated with ICS use in some studies. Although some of these studies were flawed, featured drugs that are less commonly prescribed today, or both, adverse effects from chronic ICSs use are still a cause of concern today. Current therapies are designed to be efficacious at minimal doses, limiting potential side effects, increasing adherence, and improving asthma control.
