Evaluation of the Efficiency of Single-Inhaler Combination Therapy with Budesonide/Formoterol Fumarate in Patients with Bronchial Asthma in Daily Clinical Practice

Abstract

Introduction

The effectiveness of single-inhaler budesonide/formoterol fumarate combination therapy for asthma has been previously shown for the original product. The aim of this nonrandomized, open-label, postauthorization efficacy study (PAES) real-life clinical assessment was to evaluate the clinical effectiveness of a second product (Bufomix Easyhaler ^®) in the daily clinical practice of asthma therapy.

Methods

This multicenter PAES was conducted by 220 unselected allergologists and pulmonologists who enrolled 2200 adult outpatients (age 49.8 ± 17.9 years) with asthma treated with Bufomix Easyhaler ^® for at least 14 days before enrolment. Asthma control was assessed during three subsequent visits with 8–12-week intervals on the basis of the Asthma Control Test (ACT). Adherence was assessed with the Medication Adherence Questionnaire. In addition, patient satisfaction with Bufomix Easyhaler ^® was scored, and adverse drug reactions were recorded.

Results

The percentage of patients with well-controlled asthma or total control of asthma (ACT score 20-25 points) increased from 46.6% at the first visit to 90.8% at the third visit ( p < 0.001). In addition, the percentage of patients with poor control of asthma (ACT score less than 15 points) decreased from 14.9% to 1.2% ( p < 0.001). The adherence rate increased from 88% at the first visit to 95.3% at the third visit. Patient satisfaction with the use of this dry powder inhaler increased with the duration of its use. Only one adverse drug reaction was reported.

Conclusion

The results obtained confirm the effectiveness of Bufomix Easyhaler ^® in the treatment of asthma in outpatient adults in daily clinical practice.
