Major research findings

Ciclesonide nasal spray is a corticosteroid under development for the treatment of allergic rhinitis. 4 This medication is converted to its active metabolite, desisobutyryl-ciclesonide (des-CIC), in the upper and lower airways. 4 Studies have shown that des-CIC has a long-lasting anti-inflammatory effect in human nasal and bronchial epithelial cells. 4 Ciclesonide nasal spray is delivered as a hypotonic spray via a metered-dose pump. 3 After intranasal administration, the systemic exposure to ciclesonide and des-CIC is low. 3 This is further reduced by high protein binding and rapid first-pass clearance. 3 Studies have demonstrated that ciclesonide nasal spray is effective in reducing nasal symptoms in adolescents and adults with moderate to severe seasonal allergic rhinitis. 3 It has also been shown to be effective in individuals with perennial allergic rhinitis. 3 Notably, ciclesonide nasal spray has been formulated without benzylalkonium chloride or phenyl ethyl alcohol, excipients known to hinder mucociliary transport and cause discomfort. 2 The hypotonic suspension used in the formulation optimizes intranasal absorption. 2 Ciclesonide nasal spray has a lower spray volume compared to other intranasal corticosteroids. 2 Additionally, it has not been observed to cause cortisol suppression or have additive effects on the hypothalamic-pituitary-adrenal axis when used alone or in combination with inhaled corticosteroids. 2 The efficacy of ciclesonide nasal spray has been established in pediatric, adolescent, and adult patients with allergic rhinitis. 2 The onset of action can be as early as one hour after administration. 2 A study involving allergen provocation in individuals with allergic rhinitis revealed that ciclesonide nasal spray significantly improved nasal airflow, obstruction, itching, and rhinorrhea. 1 Importantly, ciclesonide nasal spray has demonstrated a favorable safety profile, even in patients as young as two years old. 2

Benefits and risks

Benefits summary

Ciclesonide nasal spray has been shown to effectively reduce nasal symptoms associated with allergic rhinitis, including nasal congestion, sneezing, and runny nose. 3 It has been found to be effective in both seasonal and perennial allergic rhinitis. 3 The medication has a rapid onset of action, with symptom improvement observed within one hour of administration. 2 Furthermore, ciclesonide nasal spray has been formulated to optimize absorption and minimize irritation. 2 It is generally well tolerated and does not appear to have significant adverse effects on adrenal function. 6 The low systemic exposure to the medication further contributes to its favorable safety profile. 3 Ciclesonide nasal spray is considered a viable treatment option for individuals with allergic rhinitis, including children as young as two years old. 2

Risks summary

While generally well tolerated, ciclesonide nasal spray can cause side effects such as nasal inflammation, nosebleeds, and altered taste. 3 The long-term effects of this medication are still under investigation. 2
