Patient satisfaction with beclomethasone dipropionate nasal aerosol device with integrated dose counter during daily use.

Some patients with allergic rhinitis (AR) may prefer a "dry" intranasal corticosteroid aerosol to avoid certain sensory perceptions such as the "wet feeling in the nose" and the "dripping down the throat" associated with aqueous nasal sprays. A nonaqueous hydrofluoroalkane-propelled beclomethasone dipropionate (BDP) nasal aerosol with an established efficacy and safety profile was approved to treat the nasal symptoms associated with AR in adult and adolescent patients. This study was designed to evaluate ease of use and patient satisfaction with the BDP nasal aerosol device in patients with perennial AR (PAR). In this phase 3, randomized, double-blind, parallel-group, placebo-controlled study, eligible patients (≥12 years of age) with PAR were randomly assigned to receive BDP nasal aerosol at 320 micrograms/day or placebo for 6 weeks. At the end of the treatment period, patients assessed device ease of use and satisfaction with the device using a questionnaire with a 5-point representative scale (not at all, not very, neither nor, somewhat, very [certain/easy/satisfactory]). Nearly all patients (89.7%) reported that the BDP nasal aerosol device with integrated dose counter was "very easy" or "somewhat easy" to use. The majority of patients (87.5%) also indicated that it was "very easy" or "somewhat easy" to tell when the device was empty, compared with only 42.3% who were "very certain" or "somewhat certain" of being able to tell when previously used aqueous nasal spray devices were empty. Overall, patient satisfaction with the BDP nasal aerosol device was high: 65.7% responded that they were "very satisfied" or "somewhat satisfied" and only 3.6% were "not satisfied at all" or "not very satisfied." These results indicate that the majority of patients considered the BDP nasal aerosol device easy to use and reported a high degree of satisfaction with the device compared with other nasal sprays they had used in the past.

Beclomethasone dipropionate nasal aerosol with an integrated dose counter: functionality and performance.

Consistent medication delivery is critical for disease control including symptom management of allergic rhinitis (AR). Available aqueous intranasal corticosteroid devices lack an accurate dose (actuation) counter, which may lead patients to prematurely discard a unit or use a unit beyond its labeled number of actuations, therefore impacting patient adherence. Beclomethasone dipropionate (BDP) nasal aerosol, a nonaqueous hydrofluoroalkane formulation in a device with a novel integrated dose counter and an established efficacy/safety profile, was approved to treat AR-associated nasal symptoms in adolescent and adult patients. This study was designed to evaluate performance of the BDP nasal aerosol device with an integrated dose counter in perennial AR (PAR) patients. In a 6-week, double-blind, placebo-controlled study in PAR patients (≥12 years), patients were randomized to receive once-daily BDP nasal aerosol at 320 micrograms or placebo. In addition to assessing the primary efficacy end point, patients evaluated the performance of the device and reliability, accuracy, and functionality of the dose counter. Concordance between daily patient-reported actuations and dose counter readings was assessed by classifying discrepancies into four categories: "fire not count," "count not fire," "count unknown fire," and "count up unknown fire." Analysis was performed for the total device completer population (n = 374), which included all randomized patients completing ≥80% of actuations during the last 4 weeks of treatment. Low discrepancy rates were shown for all discrepancy categories. Of 41,891 patient-reported actuations, only 159 discrepancies (diary versus counter) were noted, resulting in an overall discrepancy rate of 0.38 per 100 actuations. The medically important discrepancy rate of "fire not count" was low (0.09 per 100 actuations). Overall, 79.1% of patients reported zero discrepancies, 9.4% reported one discrepancy, and 6.4% reported two discrepancies. These results showed the functionality and reliability of the BDP nasal aerosol device with an integrated dose counter in a clinical setting. (ClinicalTrials.gov identifier: NCT01134705.).
